Key Features
- Automatic Movement: At the heart of this watch is Seiko’s self-winding automatic movement, which harnesses the natural motion of the wearer’s wrist to keep time. This eliminates the need for battery replacements and ensures consistent, reliable performance over time. Ideal for watch enthusiasts who appreciate mechanical craftsmanship, the movement requires only regular wear or occasional use of a watch winder if not worn daily.
- 200-Meter Water Resistance: Rated for depths up to 200 meters (660 feet), this watch is suitable for recreational scuba diving, snorkeling, swimming, and other water-based activities. It meets ISO standards for diving watches, ensuring safety and accuracy when tracking time underwater.
- Uni-Directional Rotating Bezel: A critical feature for divers, the bezel rotates only in one direction to prevent accidental overestimation of dive time. This safety mechanism helps avoid dangerous miscalculations during underwater excursions by ensuring elapsed time is always read correctly.
- Blue Dial with Luminous Markers: The deep blue dial offers high contrast and excellent legibility in various lighting conditions. Luminous hands and hour markers absorb light and glow in low-light or dark underwater environments, enhancing visibility when it matters most.
- Blue Silicone Strap with Tang Clasp: The flexible, durable silicone band is resistant to saltwater, sweat, and UV exposure, making it ideal for prolonged use in marine environments. The tang clasp provides a secure, adjustable fit that stays comfortably in place during active use.
- Silver-Tone Stainless Steel Case: Constructed from corrosion-resistant stainless steel, the case protects the internal movement while maintaining a sleek, polished finish. Its 43.2 mm diameter offers a substantial yet balanced presence on the wrist, suitable for medium to large wrist sizes.
