Key Features
- Automatic Movement (Caliber 4R35): Powered by natural wrist motion, this self-winding mechanism ensures consistent accuracy without batteries. The 24-jewel construction reduces friction and enhances durability for long-term reliability.
- 200m Water Resistance: Engineered for serious water sports, this watch is suitable for recreational diving, snorkeling, and swimming. The screw-down crown and screwed case back provide a secure seal against water intrusion.
- Unidirectional Rotating Bezel: Essential for divers, the bezel allows for precise tracking of elapsed time underwater. Its one-way rotation prevents accidental overestimation of dive time, enhancing safety.
- Luminous Hands and Markers: Equipped with Seiko’s proprietary luminescent material, the hands and hour markers glow brightly in low-light conditions, ensuring clear readability during night dives or dim environments.
- Hardlex Crystal: The mineral crystal offers excellent scratch resistance and clarity, protecting the black dial while maintaining a crisp, unobstructed view of the time.
- Silicone Strap with Buckle Clasp: The flexible, hypoallergenic silicone strap provides a secure and comfortable fit, even during prolonged wear or in wet conditions. The buckle clasp ensures the watch stays firmly in place.
- Date Display: A practical date window at the 3 o’clock position adds everyday functionality without compromising the watch’s clean, symmetrical design.

Important Notes
While this watch is designed for water resistance up to 200 meters, it should not be used for high-pressure water activities such as scuba diving beyond recreational limits or professional saturation diving. Avoid pressing buttons or operating the crown while submerged. The automatic movement may require manual winding if not worn regularly for extended periods. For warranty details, customers should refer to the manufacturer’s official policy via the provided link. The watch comes in original packaging measuring 5.63 x 3.66 x 3.5 inches and weighs 5.29 ounces. As an automatic timepiece, it does not rely on a traditional battery, though the product listing notes one unknown battery may be required—likely related to internal components or packaging materials. Regular maintenance and professional servicing are recommended to preserve performance and longevity.
