But before you do, let’s dive deep into what makes the Khaki Navy Scuba Automatic GMT a standout in Hamilton’s lineup.

A Nautical Design with Global Appeal

The Hamilton Khaki Navy Scuba Automatic GMT isn’t just about functionality — it’s about style that speaks of journeys, both above and below sea level.

Case & Dial: Built for the Elements

At 43 mm in diameter and 13.9 mm thick, the stainless steel case strikes a balance between presence and wearability. The brushed and polished finishes transition effortlessly, catching light in a way that feels both rugged and refined.

The dial is a crisp white with a subtle grained texture, offering a clean backdrop for the applied hour markers. Coated in light green Super-LumiNova, those markers glow brightly in low-light environments — an essential feature whether you’re on a night dive or catching a red-eye flight.

The red-tipped GMT hand stands out against the white dial, instantly drawing your eye to the second time zone. It’s a pop of color that’s functional and stylish.

Bezel & Crystal: Form Meets Function

The bidirectional ceramic bezel is more than just a pretty face. Its 24-hour scale allows you to read a second time zone quickly and clearly. The black ceramic insert resists scratches and fading, ensuring your watch keeps its fresh-from-the-box look for years.

Protecting the dial is a sapphire crystal with anti-reflective coating, so whether you’re in bright tropical sunlight or dimly lit ship cabins, the time remains perfectly legible.

Mechanical Excellence Beneath the Surface

Hamilton equips the Khaki Navy Scuba Automatic GMT with the H-14 automatic calibre — a movement based on the Swatch Group’s renowned Powermatic 80.

H-14 Automatic Movement

This engine delivers:

• 80-hour power reserve — nearly double the industry standard, letting you set it down Friday and pick it up Monday without losing time.
  

• 3 Hz beat rate — a balance between smooth sweep and long power reserve.
  

• Nivachron anti-magnetic balance spring — reducing the impact of magnetic fields from electronics, so your watch stays accurate whether you’re navigating a cockpit or carrying your laptop bag.

True GMT Functionality

Unlike “office GMT” watches, the Khaki Navy Scuba GMT is a true traveler’s GMT. This means the local hour hand is independently adjustable in one-hour increments without stopping the movement, so you can change time zones without disrupting your watch’s accuracy.

The red GMT hand points to the 24-hour scale on the bezel, letting you track a second time zone — perfect for keeping an eye on your home port while you’re abroad.

Ready for the Deep Blue

This is not a “desk diver.” The Khaki Navy Scuba Automatic GMT is rated for 30 bar (300 m) of water resistance, making it suitable for serious diving.

Key dive-ready features include:

• Screw-down crown and caseback for enhanced sealing.
  

• Robust gaskets to handle pressure at depth.
  

• Highly legible lume to read the time even in pitch-black waters.
  

With these specifications, you could take this watch on a wreck dive in Key Largo one day and a business trip to London the next.

Wearing Comfort & Versatility

Hamilton pairs this model with a three-link stainless steel bracelet. The solid links add reassuring weight, while the folding clasp with push-button release ensures a secure fit.

The bracelet tapers from 22 mm at the lugs to a narrower width at the clasp, providing both visual balance and ergonomic comfort.

Variants for Every Style

While the H82555150 is the stainless steel, white-dial version, Hamilton also offers:

• A bronze-cased model with black dial and NATO strap — developing a unique patina over time.
  

• A blue-dial variant for those who want a bolder nautical look.

Value That’s Hard to Beat

In a market where Swiss-made GMT divers often climb into the several-thousand-dollar range, the Khaki Navy Scuba Automatic GMT stands out. At around $1,395 USD for the steel model, it offers:

• Genuine Swiss construction.
  

• True GMT movement.
  

• 300 m water resistance.
  

• Ceramic bezel and sapphire crystal.
  
  

This combination is rare at this price point — making it a savvy choice for both seasoned collectors and first-time luxury watch buyers.

Caring for Your Hamilton Khaki Navy Scuba GMT

A fine watch deserves proper care. Here are some tips to keep your timepiece at its best:

After Saltwater Use

Rinse the watch in fresh water to prevent salt build-up, then gently dry it with a soft cloth.

Regular Servicing

Have your watch serviced every 4–5 years by an authorized Hamilton service center to ensure water resistance and movement health.

Avoid Extreme Temperatures

While the Nivachron spring resists magnetism, extreme heat or cold can still affect performance. Avoid leaving your watch in a hot car or freezing environment for extended periods.

Hamilton’s Nautical Legacy

Hamilton’s history stretches back to 1892, but the Khaki Navy line reflects the brand’s more adventurous side. Drawing inspiration from military marine chronometers and professional dive watches, Hamilton’s Navy collection marries technical precision with aesthetic appeal.

The Automatic GMT variant adds a new layer — appealing not just to divers, but also to global travelers who need a reliable second time zone.
