Does anyone have any thoughts regarding this CK 2907-1 with "SEEMASTER" on the caseback? My friend that sold it to me is a longtime and very knowledgeable vintage Omega guy said that this is a rare engraving mistake and that he acquired the watch from the family of an Omega dealer who was the original and sole owner, and that he has seen a couple of other similar examples over the years. Also, any thoughts about the present value of the watch? Haven't seen too many for sale. Comments welcome. Thanks all.
