SEIKO SRPH75 Automatic Dive Watch for Men – Prospex Special
Product Overview
The SEIKO SRPH75 Automatic Dive Watch is a purpose-built timepiece from the renowned Prospex Special Edition series, designed for men who demand precision, durability, and professional-grade performance. Engineered for underwater exploration, this dive watch combines Seiko’s legacy of reliable automatic movement with essential features for serious diving and everyday wear. With a 200-meter water resistance rating, it meets ISO standards for diving watches, making it suitable for recreational diving, snorkeling, and water sports. The watch features a self-winding mechanical movement that harnesses energy from wrist motion, eliminating the need for battery replacements. Its bold black dial with high-visibility LumiBrite markers ensures readability in low-light conditions, while the unidirectional rotating bezel allows divers to track elapsed time safely. Built for both function and style, the SRPH75 delivers the rugged dependability expected from a Prospex Special Edition, whether you’re exploring ocean depths or navigating city streets.
Key Features
- Automatic Self-Winding Movement: Powered by Seiko’s reliable 4R36 caliber, this movement operates without batteries by converting the natural motion of your wrist into energy. It also features manual winding capability and a 41-hour power reserve, ensuring consistent performance even when not worn daily.
- LumiBrite Hands and Markers: The watch uses Seiko’s proprietary LumiBrite technology on the hour markers and hands, providing exceptional brightness and long-lasting glow in dark or underwater environments. Unlike traditional luminous materials, LumiBrite charges quickly under any light source and remains visible for hours.
- Unidirectional Rotating Elapsed Timing Bezel: The black bezel rotates in one direction only, a critical safety feature for divers to prevent accidental overestimation of dive time. It allows precise tracking of elapsed time underwater, essential for safe ascents and decompression planning.
- 200M Water Resistance: Rated for depths up to 200 meters (660 feet), this watch is suitable for recreational scuba diving, swimming, and surface water sports. It meets ISO 6425 standards for dive watches, ensuring reliability under pressure.
- Hardlex Crystal with Anti-Reflective Coating: The dial is protected by durable Hardlex mineral crystal, offering scratch resistance and clarity. The anti-reflective coating enhances visibility by reducing glare from sunlight or artificial light.
- Matte Black Stainless Steel Case: The 45mm case is crafted from corrosion-resistant stainless steel with a matte black finish, providing a sleek, tactical appearance that resists wear and maintains its look over time.
- Black Silicone Bracelet: The flexible, water-resistant silicone strap ensures a secure and comfortable fit, even when wet. It’s designed to withstand saltwater, UV exposure, and prolonged wear, making it ideal for active use.
