A truly special offering, this Piaget Ref. 15958 is an exceptional example of the brand’s mechanical ingenuity and refined casework. Housed in a solid yellow gold case, this annual calendar model remains completely original and unpolished, showcasing a warm natural patina and subtle oxidation that speaks to its careful preservation over the decades. The standout feature is its rare white nipple dial—a configuration seldom seen on this reference, as most were produced with standard indices. The dial remains in pristine condition, with sharply defined text and applied markers that catch the light beautifully. Paired with matching hands and a balanced triple-calendar layout, it offers a striking presentation. Inside, the movement was fully serviced in July 2025 and continues to run smoothly with all calendar functions operating as intended. This example is offered on a classic black 18/16mm alligator strap and retains its original yellow gold Piaget-signed pin buckle—an increasingly hard-to-find detail that completes the piece. A rare chance to acquire one of Piaget’s most collectible and mechanically interesting vintage models in original condition. **Reference:** 15958 **Size:** 33mm 🏞️ [Album](https://imgur.com/a/7BSk4vH) ☑️ [Timestamp](https://imgur.com/a/XKKeBRk) 📜 Includes: Custom [travel pouch](https://bogossia.com/products/travel-carrying-case) ($50+ value) 💵 Price: $7,275 + FREE overnight shipping with FedEx fully insured. 🔥 Follow us on [Instagram](https://www.instagram.com/bogossiajewelers) 📍 Location: New York 🔒 Authenticity: 100% guaranteed, buy with confidence.
