I'd like to enquire about this JLC 2-register chronograph that's for sale. It's in steel, and said to be 37mm without crown. I have only a little bit of experience in vintage watches, and not enough expertise, so I'd like to seek your help.
I consulted Zaf's book (pages 74-77) and as far as I can tell about this watch for sale:
1. It has a UG calibre 285 , which is consistent as far as I know
2. The dial resembles the one on the top of page 76, and it looks quite patina-ed and faded, so it's not a recent redial, and I think it's not refinished (but I could be wrong!)
3. Movement looks a bit dirty? Probably needs servicing.
4. The serial dates it to around 1957/1958?
Could I ask:
1. Did these 2-register chronos ever come in SS in that 37mm size? Or is this chromed nickel? Or worse, is this a franken?
2. Does the movement look OK?
3. Are there any other "red flags" or warning signs about the watch?
Thanks in advance for your help!
