I purchased a nice old Longines square faced Ladies manual wristwatch via an estate auction Just yesterday. I know nothing about it. Searched and searched but saw nothing even similar. On the face there is a number under Longines - 215. On the lower face says shock resistant. The back indicates stainless F-2. I opened the watch and it has the number 511 P swiss. further down it says Wotania LTD M6. Between the watch and where the band attaches, are four black gemstones on each side. The base area measures 1/2" top to bottom and 3/4" from stem across. Beginning where the bands attach on each side the total length of the watch is 1 1/2". I greatly appreciate any Info and or value you can give.
Value is typically the scrap value of the gold & diamonds + something like $25-50. So guessing, something like $150-175 if you can get it. There is very little demand for this style of watch right now.
