Hello everyone
I've had this pocket watch in my collection for years and haven't found much information on it.
Also first time posting on this site, still trying to figure it out. Thanks, k

Nice watch! Is there a serial number visible on the movement? The adjustment/jewel stamps could be either 1909-1913 or after 1922. I am almost certain yours is from the earlier period from the stamps order and from a similar watch in the 1913 ad from the thread below (in the google results Jim shared)


There's some history on the thread. Here's a bit more. The firm of J. (Js.) Calome-Robert ended in 1892, splitting into Hanhart & Cie and Sandoz & Breitmeyer (both "succ. de Js. Calome-Robert"). In 1902, George-Jules Sandoz and Jules Breitmeyer split up into separate firms, again each taking "succ. de Js. Calome-Robert." Marks and movements were split between them, with Breitmeyer filing JCB variants of some original JCR marks.

The previous thread questions the quality of his movements, but his work will speak for itself. He achieved many top-grade chronometer bulletins at the Neuchatel Observatory and many bulletins from the Chaux-de-Fonds bureau. Yours is a good piece, even with 2 adjustments.
