Seiko Prospex 1968 Heritage GMT Diver SPB519J1 – Automatic, 300 m

The SPB519J1 is a modern interpretation of a true Seiko classic. Inspired by the legendary 1968 diver, this Prospex GMT Diver combines historical design with contemporary technology. The result is a professional dive watch that not only excels underwater but also impresses with its functionality and presence in everyday life.

Inside, the automatic 6R54 movement with integrated GMT function keeps time. The additional 24-hour hand allows you to read a second time zone – ideal for frequent travelers or anyone who travels between different locations and time zones. With a power reserve of up to 72 hours , the watch will keep running reliably even after several days.

With a water resistance of 300 meters, the SPB519J1 is a true professional diver's watch. The unidirectional rotating ceramic bezel is exceptionally scratch-resistant and underscores the watch's robust character. Generously sized hands and indices with LumiBrite ensure excellent legibility – day, night, and underwater.

Visually, the watch remains close to the historical model, but interprets it in a contemporary way: clear lines, functional design and a confident appearance that consistently continues Seiko's diving watch tradition.
