Watch was recently serviced and keeps good time.  Manual wind. Clearly marked "Tiffany & Co  New York" on the dial. Should fit a 7 inch wrist. Case and band are 18k yellow gold. There are approx 2.88 carats (total weight) of BEAUTIFUL diamonds....after all, it IS Tiffanys!  I am not positive how to measure the watch, so photos are attached which show the FACE to be about 17.3mm and the CASE to be about 23.33mm.  Weighs approx 35 grams.  AS ALWAYS....if you have any questions or want more photos..... JUST ASK !!!!!!!!!!!!
