Great thread. This one has a 30.6mm case, caliber 26.5 SOB and is signed RATTRAY & CO, DUNDEE on the dial. I once ordered a very expensive balance to finish the project but somehow it was thrown away in its envelope by mistake.
And also at 30.6mm is this nice Omega CS (I) with lots of tabacco build up on the dial, and once again in non-working condition.
A gift from a good friend and forum member and worn by our eldest daughter and I should ad that although she wears an I Watch daily this is the watch whenever she dresses up 👍
Here's my "vintage" 1988 Seiko that seemed normal size to me when I bought it. 32mm by 38 by 5.5. Feels like a dime on my wrist now. Though most of the watches I currently wear are still in the 36-39mm range, but thicker.
From top to bottom:
LeRoy day/date 23.8mm
Feldenheimer (Oregon jeweler,1936) 26.4mm -- powered by Omega cal. 23.4SC
Longines (1941) 27.4mm
Bulova mono-pusher chronograph (1942) 28.4mm -- reported to be the smallest production chrono movement
