Seiko Prospex Automatic Diver's Turtle PADI 60th Anniversary watch blue dial steel bracelet, 45 mm

An anniversary collaboration at the heart of underwater exploration

On the occasion of PADI’s 60th anniversary, Seiko strengthens its long-standing connection with the world of diving through a special Prospex Diver's Turtle HBB002 edition limited to 8 000 pieces. This collaboration celebrates a shared vision: making diving safer, more accessible, and better structured, while honoring the professional standards that have shaped the discipline for six decades. This anniversary edition continues the Prospex dive watch legacy, designed to accompany both everyday explorers and technical divers.

A deep-sea inspired dial and a functional bezel

The Prospex HBB002 stands out with a dial crafted in a deep blue tone, evoking the shifting light beneath the ocean’s surface. Its textures and reflections mirror the movement of water at depth, reinforcing its identity as a PADI anniversary dive watch. The generously applied LumiBrite indices and hands ensure optimal legibility, even in the darkest underwater environments. The unidirectional rotating bezel allows precise measurement of dive time and ensures maximum safety by preventing accidental adjustment.

A proven and robust automatic movement

At the heart of the watch, Seiko’s in-house 4R36 automatic calibre ensures reliable and consistent performance. This mechanical movement, featuring both automatic and manual winding, operates at 21,600 vibrations per hour and offers an approximate 41-hour power reserve, along with hacking seconds and day/date functionality. Built for durability, it reflects Seiko’s pragmatic approach: a reliable, precise movement designed for demanding environments.
