Seiko Prospex SFK001J1 Solar GMT Diver's Watch
The Seiko Prospex SFK001J1 is a robust and versatile Solar GMT Diver's Watch, combining Seiko's renowned dive-watch expertise with the convenience of solar-powered technology and a second-time-zone function. Part of the Prospex collection, this model features a striking blue dial with a textured pattern, complemented by a vibrant orange GMT hand for easy second-time-zone reading. The design is inspired by Seiko's popular "Sumo" dive-watch style.
Powered by Seiko's Calibre 5K65 solar movement, the SFK001J1 converts light into energy and provides approximately 9 months of power reserve when fully charged. The GMT function uses a dedicated 24-hour hand to display a second time zone, making this an excellent choice for frequent travellers as well as diving and outdoor enthusiasts. It also features a practical date display, quick-start function and overcharge prevention.
Built for serious underwater use, the 45mm stainless steel case is fitted with a scratch-resistant sapphire crystal with anti-reflective coating, a unidirectional rotating bezel and screw-down crown. With 200 metres of diver's water resistance, LumiBrite on the hands, indexes and bezel, and a stainless steel bracelet with diver's extender, the SFK001J1 is designed to perform in demanding environments while remaining stylish enough for everyday wear.
