Seiko Prospex 1968 Heritage Diver's GMT 42mm SPB519J1 Watch

This model is a reinterpretation of Seiko 's classic 1968 diving watch, a high-end marine sports GMT diving watch.

On this watch, the GMT hand can be set independently in one-hour increments, and a second time zone can be displayed at a glance.

The case is made of stainless steel with super-hard coating, with a diameter of 42mm and a thickness of 12.9mm.

The crystal is sapphire with anti-reflective coating, with a screw-down crown and case back.

The bezel is made of stainless steel with a ceramic plate to protect from scratches and increase durability.

The hands and 12 markers feature Lumibrite for legibility, standing out alongside red accents on a white dial.

The bracelet is made of steel with three links that allow it to fit snugly to the wrist. It features a new three-fold clasp with a secure locking mechanism. This new clasp can be adjusted in six steps, each approximately 2.5 mm. It offers a comfortable fit at all times, adapting to changes in wrist size during diving and everyday life.

The movement is automatic with manual winding capacity caliber 6R54 with an alternation of 21,600 per hour (6 seconds), 24 jewels and a power reserve of 72 hours.

Second hand stop function

It is water resistant up to 300m.
