Seiko Prospex Automatic Diver's Watch SPB315 | Authorized Seiko Luxe Dealer | Lexor Miami
The Seiko Prospex Automatic Diver's Watch SPB315 combines professional dive performance with refined everyday versatility, featuring the thinnest case ever created for a Seiko automatic diver's watch.
The Legacy of Seiko Prospex
Seiko's Prospex line carries one of the most respected names in professional dive watches, tracing its roots back to Seiko's earliest 62MAS diver of 1965 — a design so influential it continues to shape the brand's diver collection today. Prospex watches are built to perform under real diving conditions while remaining refined enough for everyday wear.
The SPB315 continues that legacy as a modern reinterpretation of one of Seiko's most iconic diver designs, engineered with the thinnest case ever created for a Seiko automatic diver's watch.
Introducing the Prospex SPB315
The Seiko Prospex Automatic Diver's Watch SPB315 delivers exceptional comfort without compromising durability or functionality. Crafted from stainless steel with a super-hard coating, it showcases a sleek black dial accented by elegant gold-tone details, creating a sophisticated yet sporty aesthetic suited for both underwater adventures and daily wear.
LumiBrite hands and markers ensure outstanding visibility in low-light conditions, while the black unidirectional rotating bezel and recessed screw-down crown reinforce its professional diving heritage.
Reliable 24-Jewel Automatic Movement
Powered by a reliable 24-jewel automatic movement, the SPB315 offers manual winding capability, a frequency of 21,600 vibrations per hour, and an impressive 70-hour power reserve — enough to keep running through an entire weekend off the wrist without needing to be reset.
A curved sapphire crystal with anti-reflective coating enhances clarity at every angle, protecting the dial while maintaining the slim, refined profile that defines this generation of Prospex divers.
Built for Real Dive Performance
Designed for underwater adventures and daily wear alike, the SPB315 delivers 200 meters of water resistance, making it a dependable companion wherever your journey takes you. The five-row stainless steel bracelet with a secure clasp and diver's extender provides exceptional comfort and functionality, whether worn over a wetsuit or a dress shirt.
Every detail — from the recessed screw-down crown to the unidirectional rotating bezel — reflects Seiko's decades of professional dive watch engineering.
Designed for the Modern Diver and Everyday Wear
The SPB315 is built for divers, watch enthusiasts, and anyone who values genuine dive-watch engineering with a refined finish. Its slim case profile — the thinnest ever built for a Seiko automatic diver — means it wears comfortably under a shirt cuff during the week and stands up to real dive conditions on the weekend.
The black dial with gold-tone accents gives the SPB315 a more elevated, dressier presence than a typical tool watch, making it equally at home in the boardroom or underwater.

I recently visited LEXOR MIAMI to buy a RADO watch, and I must say, the experience was exceptional. The sales executive who assisted us was truly amazing. She made us feel completely comfortable throughout the entire process, patiently answered all our questions, and helped us find the perfect watch without any pressure. Her professionalism, knowledge, and warm attitude made a big difference. It felt more like being helped by a friend than a salesperson Derya
