This morning I picked up this watch in reasonably good condition but I found little information while researching it. I'm confident that a forum member could enlighten me as to what this is. The case is 41mm with wire-lugs and hallmarked 0.935, it is a hinged case, it has a single pusher and the crown looks more appropriate on a pocket watch. The dial is porcelain with no cracks or hairlines and the hands show a bit of paint loss. It has both a 30min. and 60min. registers, Inside the case back it is marked RF inside a box with cut-corners, Montbrillant W.M Switzerland. 155313, 2, 0.935 in box. The movement is signed Montbrillant W.M, 15 Fifteen Jewels, 3 Three Adjmt's, C in a diamond box. The movement is not currently working but it looks to be complete. I haven't touched this watch yet but I thought I might wait for opinions as to the best course of action.
Thanks, Jim
