I am not an authority on Rolexes but I think this is the 3/4 sized model! All stainless steel !Markings: Rolex Oyster Perpetual, Date Superlative Chronometer Officially Certified. Non-quick set date. Watch and band is in great condition , links are not solid! Keeps great time and no issues!fits my medium sized wrist. I had this for a long time and wore sparingly! Photos to come later but can can send photos if asked. I would say this is in about 90% but no promise! Asking $2,250.00 but would ask for comments from any knowledgeable collector! Payment to be discussed! Serious inquiries only, please! Thanks!
