30T1 model identification

Hello,

I recently bought this one. I was a quick deal with someone I know so I did not research it before buying... I expected a 30t2 inside but it is a 30t1. I think it may be a CK2243 (33mm) from 1939, could someone confirm? I don't know much about these models...

Also, what is the s/n range for 30t1? I think there is overlap between t1 and t2.

The reference I found here on OF :





Interestingly, while taking he picture I discovered the "Fab. Suisse" stamp. I wondered why it was missing (bought it in France), it was just discolored and barely visible to the naked eye. Obviously, added later on top of the dial so it is not galvanic.

Nice pick-up, I love the dial.

@S.H.

I think you have identified it correctly - looks like the one illustrated in AJTT

The serial range is correct for a 30 T1

BTW nice cach 👍
