More than just about any other watchmaker, Japan's Seiko has become known for offering not only multiple styles and complications in its product families, but also several different types of movements — from affordable quartz, to proprietary hybrid Spring Drive, to high-tech solar and radio-controlled, to classically traditional mechanical. However, one Holy Grail combo that has eluded Seiko and its fans until very recently is the rare GMT (aka dual-time) watch powered by a mechanical movement and priced at what most would consider entry-level for a budding collector. Fortunately, the past few years of R&D have yielded several all-new GMT-equipped, self-winding mechanical movements for the Japanese megabrand, which have found their way into several models in its modern collections. Here’s a guide to familiarize yourself with all the Seiko mechanical GMTs on the market now — and yes, all of them offer the enticing value proposition that has made Seiko a darling of enthusiasts at every level of economic means.
The Seiko 5 Sports series traces its roots all the way back to 1963 and the original Seiko Sportsmatic 5, a groundbreaking timepiece that ushered in the emblematic “five attributes” that define Seiko’s entry-level mechanical collection today. These include automatic movements, date or day/date displays in a single window, water resistance, a recessed crown at 4 o’clock, and a case and bracelet made of durable materials. Stylistically, the watches run the gamut from dress watches to field watches to divers, with all kinds of variations in between. Relaunched in 2019, Seiko 5 Sports watches still adhere to those five principles initially laid out more than half a century ago while still retaining the famously inexpensive price points that have made them so desirable — from under $100 to around $500 for the more exclusive editions.
Price: $475, Case Size: 42.5mm, Thickness: 13.4mm, Lug Width: 22mm, Crystal: Hardlex, Water Resistance: 100 meters, Movement: Automatic Seiko 4R34
Seiko introduced the first GMT complication to the Seiko 5 sports line in 2022, equipping the watches with the Japanese brand’s automatic Caliber 4R34, a recently introduced in-house movement that offers a daily accuracy between +45/-35 seconds per day and a power reserve of 41 hours. The initial three GMT models — in the classic SKX configuration paying homage to one of Seiko’s most fondly remembered, discontinued dive-watch series — come in three colorways for the dial and bezel: blue, black, and the orange version featured here, each with a central GMT hand in a contrasting color. The distinctively styled hour and minute hands keep the time on bubble-shaped indexes. The GMT hand, coated in Seiko’s proprietary LumiBrite material for nighttime legibility, is used in coordination with the bicolor, day/night 24-hour bezel, with a ring made of Hardlex glass like the crystal, to indicate a second time zone. Also evoking the much-beloved SKX series, the watches in the Sport 5 GMT family have five-link steel bracelets with polished middle rows.
Price: $435, Case Size: 39.4mm, Thickness: 13.6mm, Lug Width: 20mm, Crystal: Hardlex, Water Resistance: 100 meters, Movement: Automatic Seiko 4R34
With its dive watches well-established, the Seiko 5 collection branched out into military-flavored field watches in late 2023, installing the popular Caliber 4R34 into a new 39.4mm steel case (black PVD-coated in the Ref. SSK025 model) with a reduced but still robust water resistance of 100 meters. The dials differ from those of the SKX-influenced watches in their use of Arabic numerals and more conventional sword hands, as well as an inner 24-hour scale within the main 12-hour ring that is reminiscent of early field watches. As on the diving models, the central GMT hand is executed in a bright, contrasting color, and points to a second time zone on a 24-hour scale, this one etched into a simple steel bezel, sans bicolor sectors. The movement is on display behind a clear caseback, and the watches are mounted on either a five-link metal bracelet or, for a more military-authentic look, a pull-through leather NATO-style strap.
Seiko launched its first diver’s watch in 1965 (which was also the first diver’s watch made in Japan) and its pioneering spirit lives on in the modern Prospex collection — which today encompasses not only a wide variety of dive watches, many paying tribute to the brand’s milestone pieces from the 1960s and 1970s — but also other types of sports- and tool-oriented timepiece models for “land, sea, and air.” Prospex watches are built to be reliable in both toughness and timekeeping accuracy (Hence the umbrella term “Prospex” for the diverse collection, which stands for “Professional Specifications.”) and contain a variety of Seiko movements, from quartz to Spring Drive to mechanical, and even solar-powered, as in the Speedtimer chronograph models. It is within the “sea” and “land” sub-families that we find GMT watches with fully mechanical movements.
Price: $1,500, Case Size: 42mm, Thickness: 12.9mm, Lug-to-Lug: 48.6mm, Lug Width: 20mm, Water Resistance: 200m, Crystal: Sapphire, Movement: Automatic Seiko 6R54
Believe it or not, even though Seiko’s Prospex line essentially started in 1965 (though the Prospex "X" logo didn’t appear on dials until much later), it wasn’t until 2023 that a Prospex GMT dive watch was outfitted with a mechanical self-winding movement; previous GMTs in the collection contained quartz or Spring Drive calibers. For this milestone, Seiko chose as its host model the modern-day version of one of its most historically popular dive watches, launched in 1968. The triumvirate comprising the initial wave of Prospex 1968 Diver’s Modern Reinterpretation GMT models includes the SPB381, with a green dial and bezel, the SPB383, with those elements in black; and the limited-edition SPB385, with an ice-blue dial, a dark blue bezel, and an added strap made of recycled plastic. The cases measure 42mm in steel and 48.6mm lug-to-lug (fairly understated in the arena of Seiko dive watches); the dials are sunray-finished, with large, luminous geometric hour markers and an arrow-tipped GMT hand. With the Prospex occupying a higher tier of pricing than the 5 Sports line, these models also offer upgraded details in terms of the crystal (made of sapphire) and, most notably, the movement, the self-winding Caliber 6R54, whose power reserve is a full three days, or 72 hours. The 200-meter water resistant cases feature solid, screwed casebacks and three-link steel bracelets with a high level of brushed and polished finishing.
Price: $1,150, Case Size: 39.5mm, Thickness: 13.6mm, Lug-to-Lug: 46.4mm, Lug Width: 20mm, Water Resistance: 200m, Crystal: Sapphire, Movement: Automatic Seiko 6R54
The Prospex “Land” family is centered around the so-called “Alpinist,” a model that traces its history all the way back to 1959 — several years before the dive watch that kicked off the Prospex collection. As its nickname implies, that vintage model, actually called the “Laurel Alpinist,” was targeted at outdoorsmen such as mountain climbers. The modern version, which joined the Prospex series in 2020, takes its cues from a more recent model, the now-classic SARB017 reference from 2006, known for its cathedral hands, wedge-shaped hour markers alternating with vintage-font Arabic numerals, and a mountaineer-specific inner rotating compass bezel operated by an additional crown at 4 o’clock. Seiko added a GMT to the Alpinist line in 2023, equipping it with the same automatic Caliber 6R54 that animates the “Sea'' models, which has been tested for a daily accuracy of -15/+25 seconds. The dials of the GMTs lack the gilt details and magnifying date lens of the original, non-GMT Ref. SPB121, but adds a steel 24-hour GMT bezel, an orange-arrow-tipped GMT hand, and a more understated date display in a small round window at 4:30. Both the SPB377 (blue) and SPB379 (black) come on leather straps that match their dials.
Price: $1,500, Case Size: 38.5mm, Thickness: 12.6mm, Lug-to-Lug: 45.2mm, Lug Width: 19mm, Water Resistance: 100m, Crystal: Sapphire, Movement: Automatic Seiko 6R54
The other “Land”-based GMT model veers from the Alpinist elements in favor of adopting the aesthetic of Seiko’s first GMT watch with a rotating bezel, which, like the main inspiration for the Prospex GMT divers, dropped in the seminal year of 1968. This contemporary reissue of the watch, called the “Navigator Timer” in its original incarnation, comes in at a very compact 38.5mm diameter in steel, with a dial that faithfully re-creates the vintage model’s details, including the Seiko logo that is lower on the dial than the modern versions. The rotating 24-hour bezel, in conjunction with the thin red GMT hand, allows the wearer to potentially view not just two but three time zones at once. The horseshoe-motif solid caseback protects the Caliber 6R54 movement inside, and the case is mounted on a retro-look five-link steel bracelet.
Seiko unveiled its Presage collection in 2016, framing it as the first product family in the Japanese brand’s vast portfolio to be composed entirely of watches with mechanical movements (at least up until 2019, when several Spring Drive models were introduced into the series). Serving as a more elegant alternative to the Prospex models, which received their modern re-branding around the same time, Presage watches utilize the full range of in-house Seiko mechanical calibers and feature 100-meter water resistant cases and sapphire crystals. It is in the Presage collection that Seiko often ventures into the artisanal territory more associated with the prestigious Grand Seiko models, now standing apart from the parent company within their own brand — such as using enamels and high-end, natural-world-inspired textured motifs on their dials. The GMT-equipped Presage models are generally found within the Sharp-Edged sub-family.

I have 2, 5 Sport and 3 Prospex mostly dive type watches. Love them all! Not sure if automatics are my thing……..sometimes I want to grab a watch and go. If it is an automatic and not used in 2 days, I need to set the day and time. I think I’m more of a quartz accuracy guy!
