Seiko 6105 Automatic Diver, Cushion Case

The Seiko 6105 is a cornerstone of Japanese dive-watch history. Its sculpted cushion case, with a crown set at four o’clock and protected by the case flank, was designed for comfort and durability in demanding conditions.

A matte black dial with generous luminous markers and a rotating timing bezel deliver the legibility serious divers needed. Collectors love the 6105 for its tool-watch honesty and its distinctive presence on the wrist.

• Steel cushion case with rotating dive bezel

As with all vintage watches, we recommend keeping this piece away from water unless it has been recently pressure-tested. Details of lume aging and bezel condition are shown in the photographs.
