Below are pics of my latest acquisition, a Pierre Durand watch that is supposedly circa 1680. Loomes lists one from that time period, one circa 1617, and also one in the later 18th century. It looks like it is circa 1680 to me, but I was hoping some of you more knowledgeable people might be able to give me some information on some of the other markings, to wit: 1. Inside inner case - a crown with "IIB" beneath it. 2. Inside outer case - an "F" with a feather beneath it. 3. Watch paper - Rand & Todd, Frontgate, Glascow. Any information would be appreciated.
