Seiko is a legendary watchmaking brand celebrated worldwide for its sophisticated yet accessible creations. Known for its diverse collections spanning mechanical, quartz, and solar watches, every Seiko model combines quality, functionality, and elegant design - often inspired by Japanese culture. Seiko watches are prized for their reliability, durability, and attention to detail, making them a go-to choice for enthusiasts and professionals alike. The brand continues to push the envelope with innovative technologies like Spring Drive and Kinetic, cementing its status as a global leader in watchmaking. From its Seiko 5 Sports collection, meet this stunning GMT SSK036K1 watch - sporty, vintage, and utterly compelling. It features a silver-toned case crafted in brushed stainless steel. Round in shape, it measures 42.50 mm in diameter and 13.55 mm in thickness - dimensions perfectly suited to men's wrists. Its grooved bezel features a GMT scale on its black insert. Unidirectional, it comes in gold tone with a grooved edge. The timepiece is fitted with a flat hardlex crystal to protect the dial from shocks. The grooved crown at 4 o'clock allows you to set the hands and date window, while the screwed and transparent case back ensures a water resistance of 10 ATM.
The dial of this watch is dressed in a striking black for heightened elegance. Against this backdrop, 11 geometric hour markers mark the hours. These markers - along with the hands that sweep over them - feature Lumibrite treatment for enhanced legibility in the dark. Timekeeping is completed by a minute track interspersed with 24-hour Arabic numerals dedicated to the GMT function, driven by an orange arrow hand at the center. Hours, minutes, and seconds are read via two bold hands and a slender gold sweep hand. Finally, a date window sits at 3 o'clock enhanced by a cyclops lens, and the brand name is displayed near 12 o'clock.
This model is powered by a Japanese-made automatic movement - specifically the Seiko caliber 4R34, which keeps your watch running with precision. It features 24 jewels and oscillates at 21,600 vibrations per hour. The mechanism includes a hacking seconds device and delivers a power reserve of 41 hours.
A vintage-inspired strap accompanies this outstanding men's watch. Easy to buckle up with a simple pin buckle in stainless steel, it works for any occasion. Crafted from bovine leather in a brown tone with beige topstitching, it completes the design beautifully. Its lug width is 22 mm.
With a water resistance of 100 meters - or 10 ATM in the language of watchmaking - this bold timepiece is equally at home at a gala or in the water. Feel free to keep it on in the shower, the bath, or even during an intense swim session. Just keep in mind: our team of watch experts wants you to know this model is not designed for scuba or freediving, nor for use with high-pressure washers. Rule of thumb: showers, baths, and swimming only - and never operate the crown or pushbuttons while submerged.
