Wow ok - that’s great. Can’t wait to see all this info!
- there are 3 different models. All these 3 models have been posted on this thread;
- MK1 is the one with the radial subdial and the numbers go from 8000 to 32000;
- MK2 is the one with the cushion case and the numbers go from 58000 to 114500;
- MK3 shares the same case as MK2 but has small differences on the dial and caseback. The dial has "swiss" instead of "swiss made", the numbers are applied and the text of the logo is a bit smaller. The subdial has concentric circles, and I think it is not enamel (not sure). The numbers on the caseback are also smaller and inside the caseback we find a "2" in a box. The numbers go from 114500 to 116000;
- MK3 was also sold to the public with no numbers on the caseback, and there are some prototypes with a 7 digit number so they can be distinguished from the others;
- the gaps in the serial numbers are due to the fact that in between Perseo was responsible for some other series;
- so we have around 85000 watches made bt UG;
- with the table bellow we can date each model
Please pull out your wacthes and put all of this to the test
👍 And I'll have to translate more to see if there is something more interesting to add.
