Object description

Case and Crowns

The watch is constructed with an 18K yellow gold case measuring 37mm, a size described by the vendor as oversized for its period of origin. The case surfaces retain their original factory markings on the back and display indications of previous light polishing. The lugs are noted to remain full and even, despite exhibiting light signs of wear consistent with use.

Both crowns are fluted and integrated into the side of the case. The top crown operates the alarm function, while the bottom crown handles time-setting and winding duties.

Evidence for this section
  • “The beautiful 18k yellow gold case appears to have been very lightly polished in the past and retains full and even lugs”
  • “It retains its twin fluted gold crowns.”
  • “The top crown sets the alarm complication of the timepiece.”

Dial and Hands

The silver-toned dial exhibits vintage characteristics with signs of aging. It features applied hour indices with black central inserts and a date window positioned at three o'clock. An inner rotating disc, used for setting the alarm, is marked with a central triangle index.

The tritium lume plots located on the inner minute track have developed a dark patina. Inspection under ultraviolet light reveals that some of these plots have degraded. Additionally, the original hands exhibit a loss of the majority of their tritium material.

Evidence for this section
  • “The original silver dial remains in beautiful vintage condition with wear appropriate for its age.”
  • “The tritium lume plots on the inner minute track have taken on a dark patina”
  • “The original hands are missing most of their tritium when inspected under U.V. light.”

The watch is sold without accessories, supplied solely on a handmade leather strap. The vendor indicates that the service history is unknown, and the current functional status is reported based on the vendor's observations.

Evidence for this section

  • “The watch comes supplied on a 2pc handmade leather strap.”
