Thank you for this update! At present, I have a couple of questions. Firstly, a reference number of "6231" is higher than normal for a 1941 invoice. Secondly, why is the order number not stamped on the case-back? I do recall another reference where something similar occured. I will try to find it.
Thanks for sharing! What is your theory behind it? I don't have enough experience to draw definitive conclusions, but it is interesting that the serial number matches the reference number in the archive.
I got this offered but not sure about the dial
Here's another example called ref. 6231. The size is also 37mm and the case looks similar but the movement dates around 1950. And the dial looks like late 1930s, early 1940s.

Unfortunately, the dial in this example has been swapped from another case/reference. See photos below.
Has this watch been discussed before? If not, good eye and memory!
