This 33.5x42mm.OMEGA SEAMASTER dates to 1961 and houses a very fine automatic winding caliber 562 24 jewel movement. The gold capped OMEGA case with steel sea monster case back has an OMEGA winding crown and sleek, flat extended lugs. There are a couple minor marks on the upper lugs, but it look great overall and marks are to be expected for a watch of this age. The case back retains the original owner’s inscription. This is a great looking OMEGA that can be worn daily.
