This classic diver’s watch reflects Seiko’s diving heritage, dating back to Japan’s first diver’s watch in 1965. Beneath scratch-resistant sapphire crystal is a navy dial with bold Lumibrite-coated indices, ensuring high visibility for underwater and daily use. The red and blue unidirectional bezel adds a striking touch. The reconfigured case highlights its refined finish, while the solar-powered calibre enables a slim 11.3mm design. Rechargeable in natural and artificial light, it offers +/- 15 seconds per month accuracy and a 10-month power reserve. Seiko Prospex watches are built for durability, adventure, and performance in extreme environments.
