Seiko 5 Sport GMT SSK023K1 Watch

The Watch

Founded in 1881, Seiko is a cornerstone of the watchmaking world. Defined by unmatched craftsmanship and a relentless pursuit of excellence, the manufacture delivers cutting-edge timepieces with refined aesthetics designed to meet every need and desire. It now presents the new 5 Sport GMT SSK023K1 watch, a sporty model drawing on dive watch codes. It comes with a round case measuring 39.40 mm in diameter and 13.60 mm in thickness, sitting comfortably on the wrist. Crafted in stainless steel with a sleek satin finish in harmony with its silver tone, the case features a clean smooth bezel marked by a GMT scale in black. This surrounds a domed hardlex crystal that gives the timepiece a classic feel. The grooved crown sits at 3 o'clock for easy hand and date adjustment. Below it, a screw-down caseback with a transparent window offers a pleasing view of the movement and ensures a water resistance of 10 ATM.

The Dial

The dial of this watch is impeccably crafted, with a classic look and timeless charm. Its deep black background creates a striking contrast with all the components. The outer edge features a minute track paired with square indexes treated with Lumibrite for clear readability in the dark. The hours are marked by bold white Arabic numerals complemented by military hours displayed in a ring at the center of the dial. A date window at 3 o'clock with a silver frame and black background adds practical value. The 4 central hands are each distinct in function, shape, and color: the hour and minute hands are large silver batons filled with Lumibrite, the seconds hand is red with an oversized tip also treated with luminescence, and the final hand points to GMT hours. The design is completed by the brand's signature at 12 o'clock with its logo, while at 6 o'clock the inscriptions "Automatic" and "GMT" appear in red.

The Movement

This model is powered by a Japanese-made automatic movement. The Seiko 4R34 caliber features 24 jewels and beats at a frequency of 21,600 vibrations per hour, delivering a power reserve of 41 hours. This movement drives all central functions with outstanding efficiency.

The Bracelet

This watch is fitted with an elegant bracelet that highlights its refined, timeless construction. Crafted in stainless steel, it features 5 rows of satin-finished links that sit comfortably on the wrist. It measures 20 mm in width at the lug and closes with a deployment clasp with pushers.

Water Resistance

This model offers a water resistance of 10 atmospheres, or 100 meters - a truly water-resistant timepiece. Ready to dive into aquatic adventures with you, from puddles to the pool, this watch handles swimming without a complaint. Showering, bathing, and sport swimming are no problem. That said, Ocarat's watchmaking experts note that while water-resistant, this model is not suited for diving (professional or recreational) and should be kept away from high-pressure cleaning equipment. We also recommend not operating the crown or pushers while submerged.
