The new Seiko 5 SKX Sports Style GMT takes its inspiration from the classic (and now discontinued) SKX case shape. The smooth contours and lack of hard edges continue in the new series, and anyone who was a fan of the O.G. SKX will find plenty to like in the new models. The 316L stainless-steel case’s dimensions are largely the same, at 42.5mm in diameter with a lug-to-lug measurement of just 46mm, making for good wearability on a wide range of wrists. Seiko did a good job keeping the case height reasonable too, at 13.6mm, just 0.2 thicker than the time-only version, considering the added functionality of the GMT movement.

One notable difference from the original SKX is the lack of a screwdown crown, limiting the water resistance to 100 metres. But that’s perfectly serviceable for most people’s needs. The crown remains in its familiar spot at 4 o’clock. The bezel retains its grippy two-row texture, but there’s something new going on with the 24-hour insert. Available in three bicoloured versions to complement the dial choices, they come in a Rolex-adjacent black/blue, or black/grey, but notably, instead of being rendered in anodised aluminium, the inserts are made from Hardlex, the very material that Seiko uses in their proprietary crystals. It’s a durable choice, and an interesting alternative to the ceramic found on higher-priced watches.

About those colourways, you have three versions to select from: black/grey, a Batman-esque blue version, and a bold orange, evocative of many classic divers. The blue and orange versions get a nice sunray treatment, and the black goes for a no-nonsense flat finish. Dial text is similar to the time-only watch, with ‘Seiko’, the Seiko 5 logo, and ‘Automatic’ script all present, augmented by the ‘GMT’ signifier above 6. There’s an additional 24-hour track on the chapter ring, complementing the 24-hour scale on the bezel. Unlike the original printed markers on the SKX, the new watch sports applied indices filled with that legendary Seiko LumiBrite. Lume also lights up the traditional Seiko broad dive-style hands as well, and notably, the orange version’s hands are gold PVD as opposed to the silver of the other two.

The GMT hands stand out, courtesy of some high-visibility colour choices: Red for the black and blue versions, and black set against the orange dial. The crystal is Seiko’s Hardlex, a material more durable than mineral crystal or sapphire, but less scratch-resistant than sapphire (but still very good). One other thing to mention: The date window foregoes a day indicator as on most Seiko 5s, but adds a very Rolex-like cyclops. Whether you love it or hate it is a matter of taste, but it does add a bit of retro appeal to the overall package.

The GMT movement is based on Seiko’s Caliber 4R architecture, dubbed the 4R34, and should be as durable as any, given the company’s reputation for some of the most robust mass-market movements available. It has 24 jewels, a beat rate of 21,600 vph, and a 41-hour power reserve. Finishing is bare-bones, with a logo on the rotor, and…that’s about it. To be expected at this price point, but it’s nice for those new to the hobby just to be able to see the movement in action. As far as travel functionality, the 4R34 isn’t a true GMT, but what’s known as a caller movement, which adjusts the 24 hour hand by pulling the crown out to the first position. Again, at this price, it works just fine.

With its take on classic GMT style, added travel watch functionality, and rather good value, the new Seiko 5 SKX Sports Style GMT is as close to a sure thing as it gets. The case’s wearability recalls why we all loved the SKX, and the GMT movement makes it the perfect travel companion.
