Seiko Prospex Sea 145th Anniversary Limited Edition Automatic – HBC005

The Seiko Prospex Sea 145th Anniversary Limited Edition celebrates 145 years of Seiko's watchmaking heritage with a design that pays tribute to the brand's iconic Seiko Blue. Limited to just 400 pieces, this exceptional timepiece reimagines the legendary 1965 Japanese diver's watch with a refined 40 mm stainless steel case, creating a clean, modern silhouette that blends timeless style with professional-grade performance.

A silver-white dial is beautifully complemented by a vibrant blue unidirectional bezel and matching blue seconds hand, creating a striking contrast that reflects Seiko's enduring brand identity. LumiBrite-coated hands, markers, and bezel ensure outstanding legibility in low-light conditions, while a domed sapphire crystal with an anti-reflective coating provides exceptional clarity and scratch resistance.

Powering the watch is the Seiko Caliber 6R55 automatic movement, offering manual winding capability and an impressive 72-hour power reserve for dependable everyday performance. Built for serious diving, the watch features a screw-down crown, a screw-fastened caseback, and water resistance to 300 meters, meeting the demands of professional air diving.

Finished with a durable stainless steel bracelet featuring a diving extension clasp and an individually engraved limited-edition caseback, the Seiko Prospex Sea 145th Anniversary Limited Edition is a rare collector's piece that perfectly balances Seiko's rich diving heritage with contemporary craftsmanship.
