This is the earliest OMEGA SEAMASTER I’ve ever found. This watch dates to 1948 and has the earliest automatic bumper winding movement ever produced by OMEGA; being the Caliber 28.10 Ra Sc Pc with fine Regulator and 17 Jewels. This dial and Dauphine handset are both completely original and have the original raised gold toned Arabic numerals, arrow markers and lovely patina. The stainless steel 34mm. 2491-1 case measures 34mm. with teardrop lugs extending to 44mm. Notice the large sub-seconds. This is the first time I’ve ever found one of these after 30 years collecting! This is an important OMEGA… for the collector.
