Object description

Case and Dial

The watch case is crafted from stainless steel with a diameter of 40 millimeters. It features a rotating bezel fitted with a dark blue insert characterized by a fat-font typography and a 'Kissing 40' configuration, where the numeral four and zero appear in contact. The dial is identified as an MK1 version with white printing.

The indices and hands display a warm, natural patina, described in the provided text as 'pumpkin patina'. A cyclops magnifying lens is integrated into the crystal over the date aperture. According to the source, the pearl on the bezel is a replacement piece added at a later time.
