Seiko Prospex Automatic G.M.T Diver - 110th Anniversary

Since 1965, Seiko has continuously developed the Prospex diver's watch collection, introducing new technologies, functions, and designs. This has made them popular among professional and recreational divers worldwide. Over more than 50 years, Seiko has repeatedly set the standards for sports watches and especially diver's watches. Through continuous improvements in safety, reliability, legibility, and user-friendliness, Seiko has become a leading manufacturer of diver's watches.

New movement with GMT function

Seiko now presents a new movement from the proven 6R family, which includes a GMT function and an extended power reserve of 72 hours. The caliber 6R54 is used in three new Prospex creations, which are modern interpretations of a classic Seiko model from 1968.

The watches are water-resistant up to 200 meters and feature an independently adjustable GMT hand to read the time in a second time zone without affecting the main hour and minute hands. The hands and indices have LumiBrite coating, and the scratch-resistant, unidirectional rotating ceramic bezel is equipped with a luminous marker at 12 o'clock. The new stainless steel bracelet has a slim profile and offers a secure and comfortable fit on the wrist. In addition to the classically designed green and black models, there is also a limited edition celebrating the 110th anniversary of Seiko's and Japan's first wristwatch.
