The Breitling Watch Source Forums

This watch was given to me by my grandfather. He purchased it while stationed in Paris sometime between late 1944 and early 1946. It seems to be rather unique, as I haven't seen another Breitling from that area with a similar design. It still keeps remarkably good time, giving up about a minute every 48 hours. Any help or guidance that you can give would be greatly appreciated. I know value is arbitrary, but I would like to at least make sure it's insured for an appropriate amount.
