Thank you for viewing. I am offering a vintage pocket watch from the renowned Swiss luxury watch brand, Ulysse Nardin. The case is stamped "PURE P.M" (pure platinum), confirming that the material is platinum. 【Product Overview】 Brand: Ulysse Nardin Type: Pocket Watch (Manual Winding) Case Material: Platinum (Stamped: PURE P.M) Weight: Approximately 40.6g (body only) Case Diameter: Approximately 50mm (excluding crown) Accessories: Original box (aged) Origin: Switzerland (Locle & Geneva markings) Serial Number: Engraved on the movement (90527) 【Condition】 The watch was confirmed to be working when the mainspring was wound, but the accuracy of the timekeeping cannot be guaranteed. The dial is in relatively good condition, and the case has scratches and minor imperfections. Slight dent on the back cover (see photos) The movement and the main plate are marked with "ULYSSE NARDIN LOCLE & GENÈVE". The inside of the case is stamped with "PURE P.M" and "15131" (platinum purity marking). The back cover has come off due to age-related deterioration at the joint between the back cover and the hinge. 【Additional Information】 This is a very rare model, possessing both antique and precious metal value. It is an item for luxury antique watch and precious metal collectors. Simple operation has been confirmed, but it is being sold as junk due to unknown overhaul history. 【Notes】 Due to the platinum material and age, returns are not accepted to prevent substitution. Please purchase only if you understand the deterioration and scratches due to aging. As it is a precision instrument, it will be carefully packaged for shipping. Please feel free to contact us if you have any questions.
