Uncommon Hamilton “Transcontinental A” men’s Retro Modern design time zone wristwatch in 10K yellow gold fill and stainless steel, circa 1955.

The “Transcontinental A” has a rotating disk in the center of the dial with a map of the United States and Great Britain divided into the appropriate time zones, with the local time zone marked with a gold hand and the others with gold arrows. Designed for the rapidly increasing use of telephones and air travel by businessmen in the 1950s, its purpose was to show the time in multiple locations across the United States and Europe. Priced at $95.00 in 1955, it was never a popular watch and is now somewhat uncommon. This example is in excellent condition with just a tiny amount brassing to the edges of the lugs. The stainless steel screw back is excellent and unengraved, with some light scratches. The case measures 40mm long and 33mm wide. Original dials are superb. Has new acrylic crystal. The watch is powered by its correct 17-jewel Hamilton grade 661 automatic wind movement, just serviced and running. I will set the hour hand to the buyer’s time zone prior to shipping.

Price $750.
