For years, the world of watch collecting has held a special place for the GMT complication—a feature once reserved for high-end luxury timepieces designed for pilots and world travelers. The ability to track a second time zone is not just practical; it’s a romantic nod to a world of adventure. Seiko has now shattered the price barrier with the Seiko 5 Sports GMT SSK001, an automatic GMT that delivers incredible style, function, and heritage without breaking the bank. Get an in-depth, hands-on look at the Seiko 5 GMT SSK001 to see if it’s the perfect, stylish travel watch for your collection.
First Impressions: Unboxing the Seiko 5 Sports GMT SSK001
There’s a palpable excitement surrounding the Seiko SSK001, and for good reason. It represents the alluring intersection of affordability and desirable functionality. For many enthusiasts, this is the first opportunity to own a robust, automatic GMT from a legendary watchmaker. Drawing its design language directly from the iconic and much-loved SKX dive watch series, the SSK001 feels instantly familiar yet refreshingly new. It is perfectly positioned as the ultimate travel watch for new collectors and a worthy addition for seasoned aficionados looking for a reliable and stylish daily companion.
The Iconic SKX-Style Case and Dimensions
The first thing you’ll notice is that familiar 42.5mm stainless steel case. It carries the same comfortable, fluid lines that made the SKX a legend. The combination of brushed surfaces on the top of the lugs and polished sides gives it a dynamic look that plays beautifully with light. At 13.6mm thick, it has a substantial presence on the wrist without feeling overly bulky, wearing slightly smaller than its dimensions might suggest thanks to the compact lug-to-lug measurement. It’s a masterclass in ergonomic design that feels right at home on a variety of wrist sizes.
Dial, Hands, and Lume: Classic Legibility
Seiko’s reputation for creating highly legible dials is on full display here. The deep, inky black dial of the SSK001 serves as the perfect canvas, allowing the applied indices and bold hands to pop with exceptional clarity. The real star, of course, is the bright red GMT hand, shaped like a broad arrow, which is instantly readable at a glance. As expected from Seiko, the hands and markers are generously coated with their proprietary LumiBrite, providing a powerful and long-lasting glow that makes reading the time in low-light conditions effortless.
The Two-Tone 24-Hour Bezel
Framing the dial is a striking bi-directional bezel with a two-tone 24-hour insert. The black and grey sections cleverly distinguish between night and day hours, a fundamental aspect of any GMT watch. Instead of aluminum or ceramic, the insert is protected by a layer of Seiko’s own Hardlex crystal, giving it a glossy, almost liquid-like appearance and providing excellent durability. The friction-based rotation is smooth and firm, allowing you to easily track a third time zone if needed.
The Engine: A Closer Look at the Caliber 4R34 Movement
At the heart of the SSK001 is Seiko’s in-house Caliber 4R34. This movement is a true workhorse, part of a lineage known for its incredible reliability and robustness. It brings modern features to this accessible price point, including the ability to hand-wind the movement and a hacking function that stops the second hand for precise time-setting. With a power reserve of approximately 41 hours, you can take it off for a day without worrying about it stopping. The GMT functionality is a “caller” or “office” style, meaning the 24-hour hand is independently adjustable, making it incredibly easy to track a second time zone.
How to Use the GMT Function
Using the GMT function is delightfully straightforward. With the crown pulled out to the first position, you can independently set the red GMT hand to your “home” time by turning it clockwise. Your main hour and minute hands are then set to the “local” time of your current destination. This allows frequent travelers to quickly adjust their local time upon arrival while always keeping track of the time back home. For professionals, it’s perfect for coordinating with colleagues in different parts of the world.
It’s the ideal companion for an international adventure, especially to Seiko’s home country of Japan. If a trip there is on your horizon, you can find tickets for concerts, sports, and other live events through Jasumo Tickets.
The Jubilee-Style Bracelet: Comfort and Style
The SSK001 comes fitted with a five-row, Jubilee-style bracelet that is a perfect match for its vintage-inspired aesthetic. The bracelet drapes comfortably around the wrist, with smaller links that prevent hair-pulling and allow for excellent articulation. A tasteful mix of brushed outer links and polished inner links adds a touch of visual sophistication, elevating the watch beyond its tool-watch roots. It’s secured by a familiar three-fold clasp with a push-button release and a secure lock, ensuring it stays firmly in place throughout your day.
Living with the Seiko SSK001: A Week on the Wrist
After spending a week with the SSK001, its appeal becomes even clearer. This is a watch that effortlessly transitions between different scenarios. It’s rugged enough for a weekend adventure, stylish enough for the office, and functional enough for international travel. The movement’s accuracy remained well within Seiko’s specifications, and the 41-hour power reserve proved more than adequate for daily wear. Its remarkable versatility makes a strong case for it being a true “one-watch collection” for those just starting their journey in horology.
Pros: What We Love About the Seiko 5 GMT
- Incredible Value: Getting a mechanical GMT with an in-house movement from a brand like Seiko at this price is almost unheard of. You can find the Seiko SSK001 on Amazon for a truly exceptional price.
- Timeless Design: The SKX-inspired case is a beloved classic that looks good on everyone and will never go out of style.
- Superb Legibility: The combination of a clean dial, bold hands, and powerful LumiBrite makes it incredibly easy to read in any condition.
- Reliable Movement: The Caliber 4R34 is a robust and dependable engine that brings modern features like hacking and hand-winding.
Cons: Potential Drawbacks to Consider
- Hardlex Crystal: While durable, Hardlex is more prone to scratches than the sapphire crystal found on more expensive watches.
- Pressed Clasp: The bracelet’s clasp is pressed, not milled, which can feel less premium than the rest of the watch.
- Water Resistance: With 100 meters of water resistance, it’s perfectly fine for swimming and snorkeling, but it is not a true ISO-certified dive watch.
How the SSK001 Compares to Alternatives
One of the best parts of the Seiko 5 GMT series is that you have options. While the SSK001 is a fan favorite, its siblings offer a different flavor for every taste. It also stands tall against other affordable automatic watches on the market, often outshining them with its superior brand heritage and build quality.
SSK001 vs. SSK003 (Blue) vs. SSK005 (Orange)
The choice between the three main models comes down to personal style. The SSK001 with its black dial is the most classic and versatile, easily dressed up or down. The SSK003 offers a rich blue dial and a “Batman” style blue-and-black bezel for a sportier, nautical feel. For those who want to make a bold statement, the SSK005 features a vibrant orange dial that is pure, unadulterated fun.
Final Verdict: Is the Seiko SSK001 Worth Your Money?

Frequently Asked Questions
Is the Seiko SSK001 a ‘true’ GMT watch?
Yes, it is. While enthusiasts sometimes differentiate between “caller” and “flyer” GMTs, both are true GMTs. The SSK001 is a “caller” GMT, where the 24-hour hand is set independently. This is the most common and user-friendly type of GMT movement, especially at this price point.
Can you swim with the Seiko SSK001?
Yes. With a water resistance rating of 100 meters (10 bar), the SSK001 is perfectly suitable for swimming, snorkeling, and other surface water activities. However, it is not designed for scuba diving.
Is the bezel on the SSK001 ceramic?
No, the bezel insert is made of steel with a Hardlex crystal overlay. This gives it a durable, glossy finish that is distinct from the look of aluminum or ceramic.
What is the lug width of the Seiko SSK001?
The lug width is 22mm, which is a very common size. This makes it easy to find a wide variety of aftermarket straps if you want to change up the look of your watch.
Does the Seiko SSK001 have a sapphire crystal?
No, it uses Seiko’s proprietary Hardlex crystal. Hardlex is more shatter-resistant than sapphire but less scratch-resistant. It’s a common and durable choice for Seiko watches in this price range.
