@Peemacgee this has been awesome. Great to learn so much...fun how a watch sparks this dialogue.
Anyone have a clue as to what size this might be?
If the movement is a cal. 12.68Z, and it likely is, the size should be 32-33 mm.
If the movement is a cal. 12.68Z, and it likely is, the size should be 32-33 mm.
Mine was a 23m, a little smaller movement than the 12.68z. My gut tells me it is a 33mm variety based on the scale of the crown to the case, but I could be 100% wrong on that one, as pics can be confusing.
There seem to be two case variations for these watches. The first has straight lugs like your example and the one I posed above. The second (below) are more classically curved. Is that just a difference from the time frame produced?
If it's the same movement as the one in the OP, you can guess at the size from the distance to the seconds hand center. It seems to be quite a bit smaller.
Exactly what I did. I know the actual distance from the center wheel pivot to the fourth wheel pivot on a cal. 12.68Z. So, I measure the apparent distance on my computer screen using a ruler. Then I measure the apparent diameter of the case and use cross multiplication to solve for the actual diameter of the case. I got ~32 mm.
