FC-270SW4P26 Business Timer Review: How to Set It & Price
If you have been searching for a Swiss dress watch that does more than tell the time, the Frederique Constant Classics Index Business Timer FC-270SW4P26 probably landed on your shortlist fast. It shows the day, the date, the week number and the moon phase on a clean silver dial, it measures a wrist-friendly 40 mm, and it runs on a Swiss quartz movement with a battery rated for roughly five years. It is also one of the most misunderstood watches in its price range. Online, buyers keep asking the same things: How do you set the moonphase? Does the long red-tipped hand show the month or the week? Is a quartz moonphase worth $1,495? And why do prices for "the same watch" range so widely across the internet?
This guide answers every one of those questions in plain English. You will learn how to read each part of the dial, how to set the watch step by step without fighting the pushers, what the specifications mean in daily life, how the FC-270SW4P26 compares with its sister references, and why buying from an authorized Frederique Constant dealer like Lexor Miami matters more than most shoppers realize. Whether you live in Miami, shop online from anywhere in the contiguous United States, or are simply comparing Swiss moonphase watches under $1,500, you will finish this article knowing exactly whether the Business Timer is the right watch for you.

The Quick Answer: What Is the Frederique Constant FC-270SW4P26?
The Frederique Constant FC-270SW4P26 is a men's Swiss quartz dress watch from the Classics Index Business Timer collection. It has a 40 mm polished stainless steel case that is 9.94 mm thick, an anti-reflective sapphire crystal, 60 m (6 ATM) water resistance and a black calf leather strap with a crocodile-pattern finish. Its silver dial displays hours, minutes, the day of the week, the date, the calendar week number and the moon phase. It is powered by the FC-270 caliber, based on the Swiss Ronda 706.B, with a battery life of approximately 60 months. At Lexor Miami, an authorized Frederique Constant dealer, it sells for $1,495 with a 2-year manufacturer warranty, free shipping and free returns.
That is the short version. The rest of this guide explains why those details matter, and how to get the most out of the watch from the day it arrives.
Who Is Frederique Constant, and Where Does the Business Timer Fit?
Frederique Constant is a Geneva-based Swiss watchmaker founded on a simple mission: make genuine Swiss luxury watches accessible to more people. The brand is known for in-house mechanical calibers such as the Heart Beat and the Manufacture Worldtimer, but it also builds a carefully curated line of quartz watches for buyers who want Swiss design and finishing without the daily winding or service schedule of a mechanical movement. If you are new to the brand, our overview Why Frederique Constant Watches Are a Smart Luxury Choice in 2026 covers the brand story in depth.
The Business Timer sits inside the Classics family, Frederique Constant's most traditional collection. Its purpose is right there in the name: it was designed for professionals who plan their lives around calendars, deadlines and week numbers. In much of Europe, week numbers are a standard way of scheduling projects, shipments and meetings ("let's deliver in week 46"). In the United States, they are increasingly common in corporate planning, logistics, manufacturing, retail and finance. The Business Timer puts that information on your wrist, wrapped in a classic dress-watch design that works with a suit just as well as with a weekend shirt.
There are two design directions in the Business Timer line. The older "Persuasion" style uses large Roman numerals and guilloché sub-dials. The newer Index style, which includes the FC-270SW4P26, uses slim applied indexes, a matte dial and a quieter layout. The result reads more modern and more minimal, which is exactly why the Index version has become the more popular choice for everyday wear.
How to Read the Business Timer Dial (Day, Date, Week, Month and Moonphase)
The single most common question about this watch is "what am I looking at?" The dial packs five indications into 40 mm, yet it stays legible once you understand where each one lives. Here is the full breakdown.
Hours and minutes
The two central dauphine-style hands show the hours and minutes against applied steel indexes. There is no running seconds hand cluttering the dial, which keeps the look calm and businesslike.
Day of the week sub-dial (9 o'clock)
The sub-dial on the left shows the day of the week. Its small hand advances automatically each night around midnight.
Date sub-dial (3 o'clock)
The sub-dial on the right shows the date from 1 to 31 with a small pointer hand. Like the day, it jumps forward at midnight.
Moonphase (6 o'clock)
The aperture at the bottom shows the current phase of the moon. A printed moon disc rotates slowly behind the window, tracking the roughly 29.5-day lunar cycle from new moon to full moon and back. It is the most romantic complication on the watch and the one that turns a business tool into a conversation piece.
The long central hand: week number and month
This is where most buyers get confused, and where even some retailers describe the watch inconsistently. The long, slender central hand with the colored tip is the calendar week indicator, sometimes called a "semainier." It points to a scale of week numbers (1 to 52) printed around the outer edge of the dial. Around that same perimeter, Frederique Constant also prints the months of the year, abbreviated to a single initial on the Index version. Because each week falls inside a month, the same hand tells you both the week number and, roughly, the month you are in. So when you read that the hand "points to the month," and elsewhere that it "shows the week," both are describing the same hand: the precise reading is the week number, and the month initials give you context at a glance.
Once you know this, the dial clicks into place: left for the day, right for the date, bottom for the moon, the outer ring for the week and month, and the center for the time.
How to Set the Frederique Constant Business Timer: Step-by-Step Guide
The FC-270 caliber is based on the Swiss Ronda 706.B, and its calendar must be set in a specific order. Owners who skip the order are the ones who end up with a moon that does not match the sky or a date that changes at noon. The good news: you only need to do the full setup once. After that, everything advances automatically, in sync, for years.
The watch has a crown and two small correctors (recessed pushers) on the side of the case. On Ronda 706.B-based watches, one corrector advances the date and the other advances the calendar week; typically the lower one is the date and the upper one is the week. Use the tip of a wooden toothpick or the plastic stylus supplied with many calendar watches, never a metal pin that could scratch the case. Always confirm the corrector positions in the instruction booklet that comes with your watch.
Before you start: find the date of the last full moon
The moonphase is set using a real full moon as a reference. Look up the most recent full moon before today's date. For your convenience, here are the remaining full moons of 2026 (U.S. Eastern Time):
| Full moon | Date (2026) | Day of the week |
|---|---|---|
| Harvest Moon | September 26, 2026 | Saturday |
| Hunter's Moon | October 26, 2026 | Monday |
| Beaver Moon | November 24, 2026 | Tuesday |
| Cold Moon | December 23, 2026 | Wednesday |
For dates in 2027 and beyond, any reliable moon calendar, such as the Old Farmer's Almanac, will give you the most recent full moon for your time zone.
Step 1: Set the moonphase to full moon
Pull the crown out to the time-setting position. Turn the hands forward. Each time the hands pass midnight, the moon disc advances a little. Keep turning until the moon disc is perfectly centered in the window as a full moon. This is the most tedious part of the process because it can take many rotations, but you only do it once.
Step 2: Set the day of the week of the last full moon
With the crown still out, move the hands back and forth across midnight (for example, between about 10 PM and 1 AM). On many 706.B-based watches this lets you step the day of the week without disturbing the moon you just set. Stop when the day sub-dial shows the weekday of the most recent full moon. For example, if the last full moon was Monday, October 26, 2026, set the day hand to Monday.
Step 3: Set the date of the last full moon
Turn the hands to around 6:00 AM so you are outside the restricted window (see the warning below). Now press the date corrector repeatedly until the date sub-dial shows the date of that full moon, in this example the 26th.
Step 4: Advance to today's date
Using the crown, turn the hands forward through each midnight until the date sub-dial reaches today's date. As you do, the day of the week and the moonphase advance together with it, so all three stay perfectly synchronized.
Step 5: Set the time
Set the correct time, paying attention to AM versus PM. If the date changed when you passed 12, you are in the morning; if not, keep turning. Push the crown back in.
Step 6: Set the calendar week
Press the week corrector until the long central hand points to the current calendar week number on the outer scale. Your Business Timer is now fully set.
Important: when NOT to press the correctors
Like most quartz calendar movements, the Ronda 706.B has "blocked" periods while the calendar mechanism is switching over. Pressing a corrector during those windows can misalign the display or strain the mechanism. As a rule of thumb for this caliber family:
- Date corrector: avoid using it between about 11:30 PM and 5:30 AM.
- Week corrector: avoid using it during the weekend week-changeover, from late Saturday night into the start of the new week.
The simplest habit: set the time to mid-morning before you touch either corrector, and always check the instruction booklet for the exact windows for your watch.
Quick corrections after the initial setup
Once the watch is set, you will rarely need to touch it. In months with fewer than 31 days, advance the date with the date corrector on the 1st of the following month. At the start of a new year, check that the week hand is back to week 1. When the battery is eventually replaced, the calendar may need a quick reset, which is another reason to have the battery changed by a professional who can verify everything before returning the watch.

What these specs mean on the wrist
40 mm diameter: This is the sweet spot for a modern dress watch. It is large enough to keep a five-indication dial readable, yet small enough to sit comfortably on wrists from roughly 6.25 to 7.75 inches. It does not overwhelm a slimmer wrist and does not look undersized on a larger one.
9.94 mm thickness: Under 10 mm means the Business Timer slides beneath a dress-shirt cuff without catching. For a watch with this many calendar functions, that is impressively slim.
22 mm lug width: This is a very common strap size, so finding a replacement or a second strap is easy. A brown leather strap gives the watch a warmer, more casual look; a navy or grey strap makes it feel fresher for summer in South Florida.
Sapphire crystal: Sapphire is highly scratch resistant, which matters on a watch you will wear daily, and the anti-reflective treatment keeps the sub-dials legible under bright light.
60 m water resistance: Rain, hand washing and accidental splashes are no problem. Brief swimming is possible when the seals are in good condition, but this is a dress watch on a leather strap, not a dive watch. Water, chlorine and salt shorten the life of any leather strap, so most owners simply take it off before the pool or the beach.
60-month battery: Roughly five years between battery changes is excellent. When the time comes, have the battery replaced by an authorized dealer or a qualified watchmaker who can also check the gaskets and reset the calendar.
Quartz Moonphase vs Automatic Moonphase: Is the Business Timer Worth It?
This is the debate you will find in every watch forum: should a moonphase watch be mechanical? Purists love automatic movements for their craftsmanship and the sweep of a mechanical seconds hand. That appeal is real, and if it speaks to you, Frederique Constant makes beautiful automatic moonphase watches, such as the Heart Beat Moonphase Date we cover in What Makes the Frederique Constant Classics Heart Beat Moonphase Date FC-335MC4P5 a Timeless Luxury Watch?
But for a complicated calendar watch, quartz has a practical advantage that many buyers overlook. An automatic watch stops when you leave it in a drawer for a few days. When it stops, the day, date and moonphase stop too, and you have to reset the calendar every time you pick it up again. With a watch that has four calendar indications, that becomes a chore quickly. A quartz Business Timer, on the other hand, keeps running whether you wear it daily or once a month. You set it once, and it stays correct. That is precisely why many reviewers consider a quartz moonphase the sensible choice for most people who want this complication.
The Business Timer is right for you if...
- You want a Swiss dress watch with real, useful calendar functions.
- You rotate between several watches and do not want to reset a calendar every time.
- You work with week numbers, deadlines or project schedules.
- You want a moonphase without paying mechanical-moonphase prices.
- You value accuracy and low maintenance over the ritual of winding.
Consider a different watch if...
- You specifically want to see a mechanical movement through a display case back.
- You need a sports or dive watch for regular swimming and water activities.
- You prefer a sweeping seconds hand on the dial.
Value for money
At $1,495, the FC-270SW4P26 delivers Swiss manufacturing, a sapphire crystal, a slim 9.94 mm case and a four-indication calendar from a respected Geneva brand. Few Swiss watches combine a moonphase, a week indicator and a triple calendar at this price. It is not an investment piece in the way a limited mechanical watch might be, but as a daily-wear Swiss dress watch that stays useful for decades, it offers real value.
Business Timer Index vs Persuasion vs Blue Dial: Which Reference Should You Buy?
Frederique Constant has produced several Business Timer references over the years, and their codes look almost identical. That leads to a lot of confused searches, so here is how the most common ones differ.
| Reference | Style | Dial | Markers | Strap / bracelet |
|---|---|---|---|---|
| FC-270SW4P26 | Classics Index Business Timer | Matte silver | Slim applied indexes | Black leather, crocodile pattern |
| FC-270SW4P6 | Classics Business Timer (Persuasion style) | Silver with guilloché sub-dials | Roman numerals and indexes | Black leather |
| FC-270N4P6B | Classics Index Business Timer | Blue | Slim applied indexes | Stainless steel bracelet |
Choose the FC-270SW4P26 if you want the cleanest, most versatile version. The silver dial and black leather combination is the classic dress-watch formula: it works with charcoal, navy and black suits, with business casual, and with formal evening wear. The index markers make it feel more contemporary than the Roman-numeral version, which some buyers find a little old-fashioned.
Choose a Persuasion-style reference if you prefer a more traditional, ornate look with bold Roman numerals. Choose a bracelet version if you live in a hot, humid climate and want something more water and sweat tolerant than leather. Keep in mind that the FC-270SW4P26 has a 22 mm lug width, so you can always add a second strap later to change its personality.

How to Style the FC-270SW4P26
The Business Timer is built for the office, but it is far more versatile than its name suggests.
- Business and corporate: The silver dial complements white and light-blue shirts, and the slim case slips easily under a French cuff. Match the black strap with black shoes and belt for a polished, coordinated look.
- Formal events and weddings: A silver-dial watch on black leather is a timeless pairing with a tuxedo or dark suit. The moonphase adds a subtle touch of personality without breaking dress codes.
- Smart casual: Pair it with chinos, an oxford shirt or a fine knit sweater. Swap to a brown or suede strap on weekends for a relaxed feel.
- Miami lifestyle: For dinners in Brickell, gallery nights in Wynwood or business lunches downtown, the Business Timer reads elegant without being flashy, which is exactly what many South Florida professionals are looking for.
- Gifting: Graduations, promotions, milestone birthdays and anniversaries are all natural occasions for a Swiss watch. The moonphase gives the gift a sense of meaning and permanence.
Authorized Dealer vs Gray Market and Pre-Owned: Why Prices Vary Online
If you have shopped around, you have probably noticed that Business Timer prices online can vary dramatically, from bargain listings on auction sites to full retail at authorized jewelers. Here is what is really behind those differences.
Authorized dealers
Authorized dealers buy directly from Frederique Constant and are listed on the brand's official dealer locator. Every watch is brand new, comes with the original box and papers, and is backed by the official manufacturer warranty. Lexor Miami is an authorized Frederique Constant dealer, and the FC-270SW4P26 includes a 2-year manufacturer warranty.
Gray market sellers
Gray market sellers acquire watches through unofficial channels. The watches are often genuine, but they may not carry a valid manufacturer warranty in the United States, and if anything goes wrong you are relying solely on the seller's own coverage. Serial numbers may be removed, and the watch may have been sitting in inventory for years.
Pre-owned listings
Used Business Timers frequently sell well below retail. That can be appealing, but you rarely know the battery's age, whether the gaskets are still sealing, whether the calendar has been forced during a blocked window, or whether parts have been replaced. With a calendar movement and a leather strap, those unknowns add up.
Why buying from Lexor Miami makes sense
- 100% authentic: Authorized Frederique Constant dealer, brand-new watches only.
- 2-year manufacturer warranty included.
- Free shipping and free returns on the FC-270SW4P26 within the 48 contiguous United States.

Caring for Your Frederique Constant Business Timer
A quartz Business Timer is low maintenance, but a few simple habits will keep it looking and working like new for decades.
- Battery replacement: Plan on a new battery about every five years. Have it done by an authorized dealer or qualified watchmaker who can pressure-test the case and reset the calendar. Do not leave a dead battery inside the watch for long periods.
- Use the correctors correctly: Only press the date and week correctors outside the blocked windows described above, and use a soft wooden or plastic tool.
- Protect the leather strap: Keep the strap away from water, perfume, sunscreen and heavy sweat. In Miami's humidity, rotating between two straps lets each one dry out and lasts much longer.
- Clean gently: Wipe the case and crystal with a soft microfiber cloth. Avoid harsh chemicals and ultrasonic cleaners on a leather-strap watch.
- Avoid magnets and shocks: Quartz movements are robust, but strong magnets and hard impacts can still affect them. Store the watch away from speakers and phone chargers.
- Store it properly: Keep it in its box or a watch roll when you are not wearing it. Because it is quartz, it will keep running and keep its calendar perfectly in sync.

Why the Business Timer Earns Its Place in a Watch Collection
Many watches are bought for how they look. The Frederique Constant FC-270SW4P26 is one of the rare watches that earns its place on looks and usefulness. The silver dial and slim case give it genuine dress-watch elegance. The day, date and week number make it a real working tool for anyone who lives by a calendar. The moonphase adds a sense of craft and poetry that you simply do not get from a smartwatch. And because it is quartz, all of that information stays correct whether you wear the watch every day or keep it for important meetings and special occasions.
The Business Timer also has a smart place in a growing collection. If you already own a sports watch or a diver, the FC-270SW4P26 fills the dress-watch slot. If you own an automatic dress watch, the Business Timer becomes your "grab and go" calendar piece that is always ready. And if this is your first Swiss watch, it is a forgiving, practical introduction to the world of complications from a brand with real horological credibility.

Frequently Asked Questions About the Frederique Constant FC-270SW4P26
How do you set the moonphase on a Frederique Constant Business Timer?
Pull the crown out and turn the hands forward until a full moon is centered in the moonphase window. Then set the day of the week and the date of the most recent full moon, turn the hands forward through each midnight to today's date, set the time and finally set the calendar week with the week corrector. Avoid pressing the correctors at night or during the weekend week-changeover.
Does the long hand on the Business Timer show the month or the week?
It shows the calendar week number, from 1 to 52, on the outer scale of the dial. The months are also printed around the perimeter as single initials, so the same hand gives you the week number and the approximate month at a glance.
Is the Frederique Constant FC-270SW4P26 automatic or quartz?
It is quartz. It uses the Swiss FC-270 caliber, based on the Ronda 706.B, with a battery life of approximately 60 months. Because it is quartz, the day, date, week and moonphase keep running even when you do not wear the watch.
Can I swim with the Frederique Constant Business Timer?
The FC-270SW4P26 is water resistant to 60 m (6 ATM), so splashes, rain and hand washing are fine and brief swimming is possible with intact seals. However, it is a dress watch on a leather strap, and water damages leather, so it is best to remove it before swimming, showering or going to the beach.
What size is the Frederique Constant FC-270SW4P26?
The case is 40 mm in diameter and 9.94 mm thick, with a 22 mm lug width. It fits most wrists comfortably and sits easily under a shirt cuff.
Where can I buy the Frederique Constant FC-270SW4P26 in Miami?
You can buy it at Lexor Miami, an authorized Frederique Constant dealer, at 2371 NW 20th St, Miami, FL 33142, or online at lexormiami.com for $1,495 with a 2-year manufacturer warranty, free shipping and free returns within the 48 contiguous United States.
