• Solar GMT Movement (Caliber 5K65): This is the core innovation of the SFK003J1. It's powered by any light source. The GMT (Greenwich Mean Time) function allows for tracking a second time zone via a dedicated 24-hour hand, which is often an eye-catching orange. It also features a date display.
• ISO Certified Diver's Watch: The SFK003J1 is a true dive watch, meeting ISO 6425 standards with a robust 200-meter (20 ATM) water resistance. This makes it suitable for recreational and professional scuba diving. It features a screw-down crown for enhanced water integrity.
• "Sumo" Case Design: It inherits the iconic and substantial "Sumo" case shape, characterized by its flowing lines and blend of brushed and polished finishes. The case diameter is a generous 45mm, with a thickness of around 13.2mm and a lug-to-lug distance of approximately 51.8mm. Despite its size, many reviewers find it wears comfortably due to the curved lugs.
• Unidirectional Rotating Bezel: Essential for a dive watch, the bezel is a unidirectional (one-way) rotating bezel with a green insert, allowing divers to track elapsed time. The bezel action is typically firm and precise.
• LumiBrite Illumination: Seiko's proprietary Lumibrite luminous material is applied generously to the hands, hour markers, and bezel, providing excellent and long-lasting glow in low-light and underwater conditions.
