This is an oversize 38.5mmm. gold plated-steel back OMEGA manual winding watch dating to 1954. The caliber 266 manual winding movement was just cleaned and accurate. This waffle dial with great patina, original rose toned markers and hands is completely original. Oversize OMEGA watches are becoming hard to find. This is one of the largest of all the OMEGA dress watches from the era. This watch looks better in person than the photos.
