Tiffany & Co 14K Solid Yellow Gold Men’s Vintage Automatic Watch. I could not open the back without scratching the case anymore to show photos of the movement. The minute and hour hands move when you turn the crown. If the movement is not salvageable, another movement can be put in. The watch weighs exactly 26.6 grams (17.1 pennyweight). The diameter of the round portion of the watch is apx 35mm. Lug end to lug end is apx 40mm. Between lugs apx 18mm. As shown in one photo, there is an engraving on the back dated 1963.
