Key Features
- Automatic Movement with 41-Hour Power Reserve: The watch is powered by Seiko’s reliable automatic caliber, which winds itself through natural wrist movement. Even if you take it off for a day and a half, it will keep running thanks to the 41-hour power reserve, ensuring consistent timekeeping without daily attention.
- Day/Date Calendar Display: Conveniently positioned at the 3 o’clock mark, the day and date window offers quick readability for scheduling and planning. This dual display helps you stay organized throughout your week without needing to check your phone or calendar.
- LumiBrite Hands and Markers: The watch features Seiko’s proprietary LumiBrite technology on the hour markers and hands, providing bright, long-lasting glow in low-light conditions. Unlike traditional luminous materials, LumiBrite charges quickly under any light source and remains visible for hours after dark.
- Rotating Bezel: The unidirectional rotating bezel adds sporty functionality, ideal for tracking elapsed time during activities like swimming, diving, or workouts. Its precise 60-minute graduations allow for accurate measurement of intervals.
- See-Through Caseback: A transparent caseback reveals the intricate automatic movement at work, offering a glimpse into the mechanical craftsmanship that powers the watch. This detail appeals to enthusiasts who appreciate the artistry of traditional watchmaking.
- 100m Water Resistance: Rated for water resistance up to 100 meters (330 feet), this watch can withstand splashes, rain, showering, and swimming. It’s suitable for surface water sports but not recommended for scuba diving or high-impact water activities.
- Stainless Steel Case and Bracelet: Constructed with a durable stainless steel case and matching bracelet, the watch resists daily wear and corrosion. The bracelet offers a secure, comfortable fit with a fold-over clasp for added safety.
- Blue Sunray Dial: The striking blue sunray finish on the dial catches light beautifully, adding depth and dimension. Combined with polished hands and markers, it ensures excellent legibility while enhancing the watch’s modern, athletic look.
