I honed in on this Gruen pocket watch from the 1920s for its lovely gold relief dial. It’s interesting to contrast the relatively simple finishing of the Swiss made movement in this watch with the relatively elaborate finishing on contemporary American-made pocket watch movements. The keyless works design on this watch is also very much in line with the Swiss designs that would come to dominate the wristwatch industry, in contrast to keyless works designs on American pocket watches, which were designed quite differently.
