One of the Best Affordable GMT Watches Just Transformed into a Travel-Ready Titanium Diver

The Strat-o-timer established Jack Mason’s reputation as a serious watch brand by combining impressive specs with a crowd-pleasing, vintage-inspired look.

Since debuting in 2022, the GMT dive watch has received a series of color treatments, including multiple collaborations with popular soda companies. However, it has just received its most substantial update yet, featuring a new titanium case and bracelet, along with a new dive bezel and some dial tweaks to sweeten the deal.

Jack Mason wisely stuck to the Strat-o-timer blueprint for the new titanium case and bracelet. It features the same elliptical case shape with a light brushing, measuring 40mm in width and 13.2mm in height.

The new Strat-o-timer Titanium Diver GMT comes on a titanium bracelet that matches the familiar seven-link design from the fan-favorite collection.

While the three-row bracelet offered on the steel models isn’t available, the new reference does come with an additional black FKM rubber tropical pin-buckle strap.

The Strat-o-timer’s metallurgical enhancement is accompanied by a set of minor adjustments to what was a damn-near perfect dial design. Some changes may rub fans the wrong way, but at arm’s length, it maintains the collection’s mid-century tool watch aesthetic.

Familiar, but different

Jack Mason’s most noticeable update to the dial and bezel affects how the alternate time zone is read. While it remains ceramic, the bezel insert has been switched from a 24-hour scale to a 60-minute dive scale.

This brings up the first detail fans might lament: the dual-color bezel insert. The Start-o-timer has featured solid colored bezel inserts before, but the two-tone options have become a signature detail.

With the 60-minute scale on the bezel, the 24-hour GMT track is now shuffled in with the unchanged applied baton hour markers as printed odd hours. Which brings us to the only new detail that I find to be a detraction, the semi-skeletonized GMT hand.

The Strat-o-timer’s arrow GMT hand is one of its strongest visual features and a clear nod to the Rolex GMT Master II. This replacement looks more like a traffic cone.

The other three hands are unchanged, most notably the brand’s signature tricolor counterbalance on the lollipop seconds hand. The hands, hour markers and bezel markings are still filled with blue-glowing Super-LumiNova.

One additional change is that the date window is now a circle with no frame, which clears out room for the new 24-hour track.

A “flyer” diver

When it launched the Strat-o-timer GMT, Jack Mason was an early adopter of Miyota’s caliber 9075 movement, which made “flyer,” or “true,” automatic GMTs affordable for boutique brands to produce.

It was the feature that won over the watch enthusiast community, and it continues to power the entire Strat-o-timer collection, including this new titanium reference.

It beats at 4Hz, has a 42-hour power reserve and — crucially — the hour hand is set independently with the crown at the first position.

Even more impressively, Jack Mason regulates the Miyota movement in-house to an accuracy of within +/- 5 seconds per day.

Availability and price

The most pleasantly surprising detail of the new Strat-o-timer Titanium Diver GMT is that it costs only $250 more than its steel predecessor. Even with all other specs being functionally the same, that is an excellent deal for an upgrade from steel to titanium.

Preorders are now open for the Strat-o-timer Titanium Diver GMT from Jack Mason for $1,399, with orders shipping out at the end of November.

The watch is debuting with one color option, Cobalt Blue. However, given the brand’s history, many fun and lively color varieties are likely to follow … possibly even some soft drink-related options.
