It's time I added my watches to my home owner's insurance and they have some questions about a used Chronomat I bought a couple of months ago. Specifically I am trying to figure out which model of Chronomat it is and approxiamately how old it is. The reference number is B13050.1 which shows for Vitesse and GT, but I don't think it is either of these. There are no date codes on the lugs or on the bracelet.
The bracelet is engraved "CHRONO/DUOGR near the lug where I find the model number on my Colt's and Navitimer's bracelets. It is also engrave 13696 on a link on each side which does not match the date code explanation I found in the FAQs.
Here's some pictures. (I know, it needs a good polishing. It's going to BUSA in the spring.)
Thanks for the help.
