Unusual Omega model from ca 1972. Movement number 35737841, f300hz, caliber 1250 with case reference 198.0035. The stainless steel case manufacturer has the signature CB. It is driven by a Bulova patented electric tuning fork movement 93 Y2 (also ESA 9162) with 12 jewels. So this one needs a battery now and then. Dimensions of the case is 37,5x42mm. The dial, hands and indexes are all quite perfect. The original crystal and crown are present, and the attractive De Ville logo on the back cover adds flavour to this prominent timepiece. This watch is in very good condition.
