Product Overview

The Strat-o-timer Titanium Diver GMT was designed to be a tool watch, taking the brand's flagship model and placing it the dive watch category. The 40mm shaped case and 7-link bracelet remains as identifiers of the Strat-o-timer platform, but is given an alternative identity with its full Grade 2 titanium case and bracelet. The bezel is equipped with a circular brushed ceramic bezel with a traditional dive marking layout. Inside is the Miyota 9075 GMT movement that features an independently jumping local hour hand, regulated in-house to +/- 5 seconds per day. The bezel, dial, and handset feature Grade A BGW9 to ensure long lasting glow. With a vision of becoming a legacy brand in our home state of Texas, the Strat-o-timer is assembled, and the movement regulated, in the USA.

01.

Tracks Two Timezones

The self-winding Miyota 9075 movement is engineered to precisely track two different timezones at the same time via the orange GMT hand and the 24-hour scale printed on the dial. Every movement is regulated in-house by skilled watchmakers to maintain an accuracy tolerance of ±5 seconds per day.

02.

Made From Titanium

The case and bracelet are built from Grade 2 Titanium, a material made for gear that’s meant to be used, not babied. It’s naturally lightweight, corrosion resistant, and has been fortified with an extra hardness coating for even more resilience. The Strat-o-timer Titanium Diver GMT is engineered to take on the full force of salt, sand, and sea.

03.

Ceramic Dive Bezel

The 120-click unidirectional bezel is built from ceramic and engineered to perform in unforgiving conditions. The circular brushed finish gives it a raw, utilitarian edge that complements the titanium case, while every rotation delivers a solid, confident click that feels as dependable as it sounds. It’s a functional tool purposely built for precision timing.

04.

Legible In Low Light

Legibility is essential, not optional, so the Strat-o-timer is loaded with Swiss Super-LumiNova® where it matters most. Deep pools of BGW9 luminescent material fills the bezel markings, indices, and hands for maximum clarity. In darkness, it glows a sharp blue, cutting through the black, while daylight reveals its crisp white color.

05.

Titanium 7-Link Bracelet

The Diver GMT is equipped with a brand new 7-link bracelet built from Grade 2 Titanium. Its brushed finish complements the case perfectly, creating a unified, seamless look that feels as deliberate as it does durable. Lightweight yet incredibly strong, the bracelet sits comfortably on the wrist and delivers a wearing experience that keeps up with every expedition.

06.

Quick-Adjust Clasp

The bracelet features a concealed, tool-free system for on-the-go micro-adjustments. The clasp has been carefully engineered with 9 levels of fine-tuning to ensure the perfect fit, even over a wet suit. While being worn, all the clasp’s mechanics stay hidden out of view to preserve the bracelet’s refined and uniform look.

"I purchased this watch at the Intersect watch show in Los Angeles. I love the watch!"

Best Value On The Market!

"TRUE GMT in full titanium with a beautiful 7 link bracelet and awesome rubber strap included. . . so good! I have a Tudor BB 58 GMT in my collection and this watch legitimately stands up to the same quality standards. Mine is running +/- 2 seconds a day and is a dream to wear. If you are looking for a quality GMT and like the aesthetic of this watch, just buy it now."

First JM

"I have been following Jack Mason for some time and finally pulled the trigger on the Titanium. Really impressed with the watch. Packaging is superlative. It immediately stands next to my Submariner as my favorite every day piece. Definitely looking forward to visiting the showroom to see other models in person and to add another one to my collection."
