145TH ANNIVERSARY LIMITED EDITION OF 4,000 PIECES

Seiko Prospex 145th Anniversary Limited Edition

Limited to 4,000 Pieces Worldwide

Presented in exclusive commemoration of Seiko's 145th anniversary, the Seiko Prospex 145th Anniversary Limited Edition is a masterpiece of Japanese horological craftsmanship. This timepiece belongs to the second series of anniversary limited editions, each distinguished by refined blue accents inspired by the iconic Seiko Blue — a signature hue first established in the 1960s and meticulously perfected over six decades of watchmaking excellence.

The deep blue bezel insert and striking blue seconds hand pay homage to Seiko's enduring heritage, while the silver-white dial provides an elegant contrast that lends the watch a contemporary and sophisticated character. The case design draws direct inspiration from Japan's first-ever diver's watch, introduced in 1965 — a compact and iconic silhouette that continues to define the Prospex diving collection to this day.

With water resistance certified to 300 meters (1,000 feet), a 72-hour power reserve, and a curved sapphire crystal with anti-reflective coating, this watch is engineered for both the rigors of deep-sea exploration and the elegance of everyday wear. LumiBrite luminous coating on the hands, indices, and bezel ensures optimal legibility in any lighting condition.

Each piece features an exclusive LIMITED EDITION inscription on the case back, making it not only a precision instrument but a collectible testament to Seiko's 145-year legacy of innovation and artistry.
