To celebrate the 50th Anniversary of Seiko’s diver watches the Japanese watchmaker has created a limited edition of the Marinemaster (Ref. SBDX012).

The case is steel and measures 44.3 mm in diameter by 14.6 mm thick. It is powered by Seiko’s robust automatic 26 jewel movement, caliber 8L35. What is different from the standard model is the gold accents on the bezel, hands, hour makers and dial. And, in addition to the steel bracelet, there is a special rubber strap with a gold plated pin buckle.

It is available here, limited to 1,000 pieces (price is $2500).
