Timex Deepwater Meridian 200 Automatic GMT Takes On Seiko’s 5 Sports GMT WatchRider

Timex Deepwater Meridian 200 Automatic GMT Takes On Seiko’s 5 Sports GMT

Timex has given the Deepwater Meridian 200 a new job. The 42mm diver-style watch is now an automatic GMT, with a fourth hand and a bidirectional 24-hour ceramic bezel instead of a conventional elapsed-time scale. The colour references are black TW2Y63900, blue TW2Y64000 and green TW2Y64100. Black is the most restrained choice, blue has a cooler nautical character, and green brings the most personality without turning the watch into a novelty. Each version pairs its dial with a coordinating bezel, so the colour feels deliberate rather than decorative. Announced on 31 July 2026, this is genuinely new rather than a model that has quietly lived on retailers’ shelves for months. The personality is familiar, but the specification changes are enough to make this more than a new colourway. Black TW2Y63900. Image: Timex. Blue TW2Y64000. Image: Timex. Green TW2Y64100. Image: Timex. A diver for someone who avoids deep water I am afraid of deep water but rather fond of diver-style watches, which is a little like loving hiking while avoiding cliffs. I like their neat engineering, their tough appearance, and the fact that I can admire a 200-metre rating without personally testing it anywhere below the shallow end. Timex specifies 200 metres of water resistance, a screw-down crown, screw-on case back and a sapphire crystal with anti-reflective coating. The black dial has luminous hands and markers, a magnified date, and a red GMT hand. The steel case is 42mm across, 14.5mm thick and 48...

A History and Guide to GMT Watches

The GMT watch is a bonafide product of the jet age. Though examples of dual-time watches go back to the 19th century, it was the advent of jet-powered commercial aircraft in the 1950s that drove the introduction of this icon of modern watchmaking. Perhaps the best-known example is the Rolex GMT Master, the watch that gave the genre its name. Introduced in 1955 in collaboration with the “World’s Most Experienced Airline,” Rolex designed the watch for Pan-American World Airways pilots that would allow them to have a reference for Greenwich Mean Time (also referred to as UTC or Zulu Time) while maintaining the ability to track local time. This collaboration also resulted in the most recognizable colorway for dual-time watches, Pan-Am’s blue and red colorway.   The GMT watch is a bonafide product of the jet age.

Hands-On: Seiko's Best GMT Just Got More Colorful

The Seiko SSK GMT line has slowly taken the watch world by storm, and Seiko took the SKX-style format this year and updated it with a trio of new dial formats. Earlier this year, I wrote a story on what – at the time – was every single existing SKX-style Seiko SSK GMT on the market, but that story is officially out of date. Before I get any further into this, it makes sense to establish a few things about these watches. First, they were released in 2022, creating a new wave of GMT affordability in the watch world. Why do I keep calling them SKX-style watches? Well, because the case profile is nearly identical to that of the now-discontinued icon, the Seiko SKX. The Seiko SSK001 and 003 models (the blue- and black-dial versions) are watches that I often suggest to anyone looking for a true "everyday" attainable watch. I even chose it in a video I did with Teddy where we both were tasked with building a collection under $7,000 ( let me know if you think I won). But enough lede-burying. Let’s get to the newness. In total there were three new variations released: The SSK033 with a blue and black bezel, the SSK035 with a green dial and bezel format, and the SSK036, which brings a black/brown aesthetic to the mix with a leather strap (the other two come on Jubilee-style bracelets). So let’s start with the SSK033. As an owner of the Rolex GMT-Master II with the blue-and-black bezel, I immediately zeroed in on this one. But where this clearly differs from the Rolex in term...

In-Depth: The Rolex Oyster Perpetual GMT-Master II, Materials and Mechanisms

Perhaps the most recognisable travel watch in history, the Rolex Oyster Perpetual GMT-Master was launched in 1955, just as the world was entering the Jet Age of intercontinental travel. The inaugural GMT-Master model was the ref. 6542 that sported a distinctive bezel colour-coded in red and blue to distinguish day- and night-time. The coloured bezel would go on to become a defining feature of the GMT-Master and iconic within the wider genre of travel watches. Originally made of fragile Plexiglas, the bezel evolved into a robust anodised aluminium insert in 1959, the same year the GMT-Master became the official watch of Pan American World Airways, better known as Pan Am, then the world’s biggest airline. Rolex advertising from the 1950s celebrating the first non-stop transatlantic flight by Pan Am where both pilots wore the GMT-Master The GMT-Master earned iconic status with its functionality and technical excellence, but equal credit goes to the notable personalities individuals wearing a GMT-Master who witnessed, or even made, history. Astronaut Edgar Mitchell wore one on the Apollo 14 mission that landed on the Moon in February 1971. Several United States Air Force pilots set speed records while wearing a GMT-Master, including William J. Knight in 1967. And Val Kilmer sported one while playing Iceman in Top Gun. US Air Force pilot William J. Knight set an all-time speed record of 7,272 km/h (Mach 6.7) on October 3, 1967 in an X-15 rocket plane, while wearing a GMT-Mast...

Hands-On: Greubel Forsey GMT Sport

Even within the rarefied realm of haute horlogerie, Greubel Forsey has taken watchmaking to a level of craft few others can match – not just in terms of finishing, but innovation in chronometry while also establishing its own inimitable, three-dimensional aesthetic. And now, the brand has combined all of that onto its first sports watch – the GMT Sport. While nearly identical to the existing GMT in terms of function, combining a world time with an inclined tourbillon, the GMT Sport looks nothing like any other Greubel Forsey. And its movement is mostly made of titanium, having been reconstructed to fit into the new ovoid case. Despite being strikingly different, the watch is tremendously impressive on many fronts, especially in its finishing and construction. The new look Depth rated to 100m, the GMT Sport is a large watch that is organic in shape, with no right angles, a handful of edges, and only few flat surfaces. But it has a mechanical-looking style, with lugs secured to the case by visible screws and prominent pushers. The construction is complex and masterful, with the most unusual feature being the crystal and bezel, which are curved on multiple planes. When viewed from the top, the case appears circular, but it is in fact, tonneau-shaped with an oval bezel that is curved vertically from 12 to six o’clock. To fit the curvature of the case, the crystal is also oval-shaped and curved, which further highlights the architectural depth of the movement. The circ...

Introducing: Bulgari's Unexpected Dual Time Octo Finissimo With Vianney Halter, Plus A "Dazzle" Camo Release

What We Know While I hate to repeat myself, I will yet again call something "the most surprising collaboration." I mean, it feels warranted, especially when I say that not only have the minds at Bulgari handed over the reins to collaborate with an independent watchmaker for the first time ever, but they've done so with a maximalist mind that contrasts with Bulgari's measured take on design. The Bulgari Octo Finissimo Dual x Vianney Halter. What a world. And not only that, but Bulgari allowed Halter to take an Octo Finissimo movement and work with the brand to create modules to complement the Jules Vernian steampunk design. The new movement, the BVF 200, is based on the BVL 138 and has an automatic microrotor winding system, but with modules to add a dual-time/GMT function, Day/Night indicator, and a large, rotating date. At the top right, you have the main time zone. Bottom left has another window for the GMT time (ostensibly set forward and backward with pushers on the left-hand case side, like a Patek travel time watch), a day/night indicator at the bottom right (capped by Vianney Halter's name), and a giant aperture with a date disc, highlighting the date with a small fork. All of these functions are in porthole-style apertures like those found on Halter's Antiqua. The movement runs at 3Hz and has a 60-hour power reserve. From the side, the Octo Finissimo Dual Time x Vianney Halter is noticeably thicker than previous models. That's not hard to do, since the Chronograph ...
