This is a mid-size (smaller) ROLEX OYSTERDATE dating to 1966 having an original Champagne dial. The stainless steel case measures 30mm. and is actually a men’s watch-but perfect for a lady as well. The fine (just cleaned) ROLEX manual winding movement is highly reliable; having fewer moving parts than the automatics, with less repair issues. The ROLEX winding crown is unscrewed in my pictures…sorry. it screws down perfectly. If you enjoy the look of a subtle watch. this ROLEX is perfect for you.
