Seiko King Seiko Hi-Beat Ref.5626-7000 Cal.5626 36.5mm Sep 1970

Light moves across the silver sunburst dial and the architectural planes of the celebrated King Seiko case. The non-luminous display keeps the composition crisp, allowing its considered proportions to command attention without excess. Turn the watch over and a company employee’s commemorative engraving offers a discreet reminder of the life this timepiece has accompanied.

In addition, this timepiece comes freshly serviced with all parts laid out by our professional watchmaker for all to see in the images above. Little to no other dealers do this and it’s a testament to full transparency here at Montre D’or.
