Seiko Marinemaster Jamstec Limited Edition 1968 Heritage Reinterpretation 42mm Mens Watch Blue
A 42mm steel dive watch with a blue gradient dial inspired by Seiko's 1968 Marinemaster. This limited edition collaboration with JAMSTEC features a unidirectional rotating bezel with ceramic insert, 300 metres water resistance, and a crown positioned at 4 o'clock. The dial employs satin finishing and polished translucent paint to minimise light reflection underwater. A dual-curved sapphire crystal protects the dial, whilst Lumibrite hands and indices provide visibility in low-light conditions.
The watch houses an 8L45 calibre movement, hand-assembled at Seiko's Shizukuishi Watch Studio. This hi-beat automatic movement operates at 36,000 vibrations per hour and offers a 72-hour power reserve with accuracy of +10 to -5 seconds daily. The steel bracelet features a three-fold push-button safety clasp with micro-adjustment, and the case back carries the limited edition number and JAMSTEC designation. The case is coated with a super-hard finish to resist scratching.
