Design
- Case and Bezel
- The timepiece features a stainless steel case measuring 36mm in diameter. The housing shows evidence of previous light polishing, while the lugs are described as being full and symmetrical with signs of wear. The bezel, also constructed from stainless steel, maintains its original black enamel fill and includes its luminous pearl component. The case back of the watch remains in place and features factory-applied engravings. The auction description reports that these markings are currently light due to wear but are present on the exterior of the case. The watch is supplied on a 2-piece handmade leather strap rather than a metal bracelet.
- Dial and Hands
- The watch face consists of a matte black dial. The surface displays minor speckling and spots consistent with age. The hour markers feature luminous material, described in the source as strontium, which has transitioned to a dark grey or green appearance. The dial contains a date window positioned at the 3 o'clock marker. The luminous hands are original to the piece and coordinate with the hour markers. According to an ultraviolet light inspection, the hour hand has received a small stabilizing repair to its luminous content. The minute hand is reported to show no signs of degradation or damage.
