Seiko - Prospex SPB519

A refreshing combination of blue and white

Inspired by a lifestyle steeped in marine sports, the watch has a blue ceramic bezel and silvery white dial to create a fresh and clean appearance.

Endowed with updated functionality

The 1968 Heritage Diver’s GMT Watch is powered by the Caliber 6R54, which features a GMT function that allows it to display the time in two different time zones. The watch’s specifications have been enhanced to offer 300-meter water resistance.

A new clasp designed for comfort and operability

The new clasp can be adjusted in six steps, each measuring about 2.5mm, for a total range of approximately 15mm. This marks the first time that this clasp has been adopted in a non-limited-edition model. It allows for a comfortable fit at all times, accommodating changes in wrist size during diving and daily life.

This preowned Seiko is in near mint condition with very few signs of wear. Comes with full kit, all the links for the bracelet, box and papers. Original warranty dated from 10/10/2025

Robust, clean, sexy and stylish. And containing my favourite complication .. the GMT. 300 meters water resistance and a solid case that gives a lot of confidence that this watch will last. Don't wait to get your hands on this fantastic travel/companion watch.
