The Seiko SFK001J Prospex Aqua Sumo GMT Diver presents a solar-powered timepiece boasting 200m water resistance. Its classic design features a blue dial housed within a stainless-steel case and bracelet. Seiko Prospex introduces its inaugural solar watch with a GMT hand, driven by the newly developed in-house caliber 5K62. Fondly dubbed 'Sumo' by enthusiasts for its robust size and distinctive 12 o’clock marker.

The 24-hour hand, coated in lumibrite, ensures visibility underwater, while the aqua-coloured dial adds vibrant accents to the intricately pressed pattern design. With a stainless-steel case and high-power generation efficiency, the watch guarantees resilience and performance. Powered by the Seiko in-house solar 5K65 movement, the SFK001J1 maintains an accuracy tolerance of approximately +15 /- 15 seconds per month. Encased in full stainless steel, it features lumibrite-coated hands and markers for nighttime visibility. With a case size of 45mm, thickness of 13.2mm, and lug width of 20mm, it boasts a lug-to-lug size consistent with classic Sumos at 51.8mm. Weighing approximately 190gm, this dive watch includes a screw lock crown, screw case back, and uni-directional rotating bezel. Additional functionalities comprise a date function and stop seconds hand function.

The SFK001J highlights Sapphire Crystal glass with anti-reflective coating on the inner surface and boasts a magnetic resistance of 4800 A/m. Its impeccable finish, captivating blue dial, and overall aesthetics make it a future Seiko cult classic. Crafted in Japan, this timepiece offers a solid feel and surpasses expectations - images fail to capture its true essence.
