Seiko Boutique Limited Edition

A special design in black and gold

Based on the 1968 Heritage Diver’s GMT watch and available exclusively at select Seiko Boutiques. This unique watch features a sleek black ceramic bezel accented with shimmering gold tones.

Endowed with updated functionality

The 1968 Heritage Diver’s GMT Watch is powered by the Calibre 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.
