Observed from submitted photos
The wristwatch is identified as a Hamilton Medallist, as noted by the clearly visible branding in the images. The case is labeled '10K RGP Bezel' and 'Stainless Steel Back,' indicating the use of rolled gold and stainless steel, which are typical materials for watches from this period. The condition and style, including the design of the band and the watch face, suggest mid-20th century origins.
