Seiko Prospex Sea 145th Anniversary Limited Edition Automatic – HBB001

The Seiko Prospex Sea 145th Anniversary Limited Edition honors 145 years of Seiko's watchmaking excellence with a design inspired by the brand's iconic Seiko Blue. Limited to 9,999 pieces worldwide, this commemorative diver's watch combines modern styling with the trusted performance that has defined the Prospex collection for decades.

Its silver-white dial is paired with a striking two-tone blue bezel and matching blue seconds hand, creating a fresh, balanced aesthetic that celebrates a signature color deeply rooted in Seiko's heritage. LumiBrite-coated hands, markers, and bezel provide exceptional visibility in low-light conditions, while the angular 41.7 mm stainless steel case and finely finished bracelet deliver a bold yet refined presence on the wrist.

Powering the watch is the Seiko Caliber 4R35 automatic movement, offering reliable mechanical performance, manual winding capability, a date display, and an approximate 41-hour power reserve. Designed for demanding environments, the watch features a unidirectional rotating bezel, screw-down crown, screw-fastened caseback, and 200-meter water resistance suitable for air diving.

Completed with a 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 remarkable tribute to Seiko's enduring legacy of innovation, craftsmanship, and professional dive watch design.
