1942 Gruen Doctors Watch 20mm 500-290 10k Yellow Gold

This 1942 Gruen Doctor's Watch reference 500-290 features a 17-jewel Gruen movement housed in a 10k yellow gold-filled case measuring 40 x 20mm. The rectangular case shape was specifically designed for medical professionals who needed to take pulse readings, with dimensions that made timing easier while examining patients.

An ivory dial provides clear contrast for quick time checks in various lighting conditions. Gold-filled construction consists of a thick layer of gold bonded to a base metal, offering the appearance and wear resistance of solid gold at a lower cost while maintaining durability for daily use. The watch comes with a new leather calfskin strap that provides comfortable wear on the wrist. The 40 x 20mm dimensions create an elongated profile that sits horizontally across the wrist rather than the typical square orientation of most watches.

This vintage timepiece from the 1940s represents American watchmaking during an era when Gruen was known for producing reliable mechanical movements.
