Seiko 5 Sports SSK036K1 Automatic GMT Men’s Watch – 42.5mm Black Dial, Brown Leather

Retro Sophistication Meets Global Utility

Designed for the modern traveler and mechanical watch enthusiast, the Seiko 5 Sports SSK036K1 is a standout piece within the “Specialist Style” series. This GMT timepiece is defined by its warm, retro-inspired “Mocha” aesthetic. The highly legible black dial serves as a clean backdrop for luminous gold-tone hands and applied markers, all framed by a functional bi-color 24-hour bezel in black and dark brown. A bold GMT hand ensures that calculating multiple time zones can be done effortlessly at a glance.

Advanced Caliber 4R34 Engineering

At the core of this timepiece is Seiko’s highly acclaimed Caliber 4R34 automatic GMT movement. Beating at 21,600 vibrations per hour, this mechanical powerhouse is driven entirely by the kinetic energy of your wrist. It features 24 jewels, manual winding capability, and a stop-seconds function for highly precise time setting, delivering a robust 41-hour power reserve when fully wound. The intricate mechanics of the automatic engine can be openly admired through the watch’s see-through case back.

Built for the Journey

Housed in the legendary 42.5mm SKX-style stainless steel case, the SSK036K1 is engineered to handle the physical demands of international travel and daily wear alike. The dial is safeguarded by Seiko’s proprietary scratch-resistant Hardlex crystal, which features a magnified “cyclops” lens over the 3 o’clock date window for maximum legibility. Secured by a rich brown calf leather strap and boasting a 100-meter water resistance rating, this watch bridges the gap between active sports gear and refined executive style.
