Product Overview
The SEIKO SRPE27 Automatic Dive Watch is a precision-engineered timepiece built for men who value performance, durability, and authentic dive heritage. As part of the acclaimed Prospex collection, this model stands out as a PADI Special Edition—officially licensed by the Professional Association of Diving Instructors, the world’s leading diver training organization. Designed to meet the demands of underwater exploration, the SRPE27 combines professional-grade functionality with everyday versatility. Its automatic self-winding movement eliminates battery dependency, while a 200-meter water resistance rating ensures reliable operation during recreational scuba dives, snorkeling, and other water-based activities. The inclusion of LumiBrite technology on the hands and markers guarantees excellent legibility in low-light conditions, whether you’re exploring a deep reef at night or navigating murky waters. Crafted with Seiko’s signature attention to detail, this watch delivers both technical excellence and timeless design.
Key Features
- Automatic Self-Winding Movement: Powered by the 4R36 caliber, this mechanical movement harnesses the natural motion of your wrist to stay wound. If worn regularly, it maintains accurate time without intervention. For added convenience, manual winding is also possible, allowing you to start or adjust the watch even after periods of inactivity.
- 200M Water Resistance: Engineered to ISO standards for diving, this watch is fully capable of handling the pressures encountered during recreational scuba diving. The robust case construction and secure screw-down crown ensure integrity at depth, making it a dependable companion beneath the surface.
- LumiBrite Hands and Markers: Unlike traditional luminescent materials, LumiBrite absorbs light quickly—whether from sunlight or artificial sources—and emits a bright, long-lasting glow in the dark. This feature is essential for safe timekeeping during night dives or in low-visibility underwater environments.
- Elapsed Timing Bezel: The unidirectional rotating bezel is a critical tool for divers, allowing precise tracking of elapsed time underwater. It turns only counterclockwise to prevent accidental movement that could lead to dangerous miscalculations of remaining air supply or decompression limits.
- PADI Special Edition Design: This model features official PADI branding and distinctive color accents—including a black dial with blue and red bezel markings—that honor the legacy of professional diving education. It’s a meaningful choice for certified divers, instructors, and ocean conservation advocates.
- Durable Hardlex Crystal: The watch face is protected by Seiko’s proprietary Hardlex mineral crystal, offering excellent scratch resistance and optical clarity. While not as hard as sapphire, it provides superior impact resistance and maintains its appearance through daily wear.
- Stainless Steel Case and Bracelet: The matte black stainless steel case and matching bracelet are resistant to corrosion from saltwater and humidity. The bracelet includes a secure three-fold clasp with a safety lock, ensuring the watch stays in place during active use.

Important Notes
This watch includes one lithium metal battery, primarily for initial activation or as a backup power source. However, the 4R36 automatic movement is designed to run continuously through wrist motion, eliminating the need for regular battery replacements. To maintain water resistance and movement accuracy, periodic maintenance by a qualified technician is recommended. After any significant impact or before deep dives, have the watch pressure-tested to ensure seal integrity. The stainless steel bracelet should be cleaned regularly with fresh water, especially after exposure to saltwater or sand, to prevent buildup and corrosion. For warranty details, service information, and care instructions, refer to the manufacturer’s official support channels or the documentation included with your purchase.
