Hi everybody! :D
I recently got this interesting Exacta rectangular watch from the 30's. I know the more recent Exacta that sold Russian made watches etc. I was thinking that the seller misspelled Exact (German), Exacto (pre Rado) or similar but he did not. It may be related to an Exacto company from Neuchatel :)
Anyway, I couldn't identify the movement from seller's photos. So yesterday I wasn't lazy and I gently took off the dial to take photo of the setting-lever spring and/or setting bridge.
I searched Dr Ranfft's database several times, C. Lorenz's website online and without a real result. The setting part is quite different than ETA, AS, Tschudin, Durowe, PUW, etc. Just to name a few with similar look, shape and size.
The size of the movement is 19.8mm x 25mm, and the thickness is 4.3mm. That is, of course, if I measured it correctly. I'm sending the photos below in hope someone have a Flume or similar book to demystify this. :)
P.S.: I bought the watch because the dial reminds me a bit a JLC Reverso dial. :D
