Piaget Annual Calendar Yellow Gold Rare Nipple Dial (Unpolished/Serviced)

Piaget Ref. 15958 Annual Calendar – Rare Yellow Gold “Nipple Dial”

Founded in 1874 in La Côte-aux-Fées, Switzerland, Piaget began as a movement manufacturer before evolving into one of the premier houses of Swiss fine watchmaking and jewelry. Known for ultra-thin calibers, precious metal craftsmanship, and daring design, Piaget consistently merges technical mastery with refined aesthetics. While the brand is often associated with high jewelry watches, it also has a legacy of mechanical innovation, especially during the 1970s and 1980s.

The Piaget Annual Calendar Ref. 15958 is a rarely seen complication from a period when Piaget experimented with complex mechanical calendars in elegant, slim gold cases. Crafted in yellow gold, this reference reflects the maison’s ability to pair mechanical sophistication with luxurious execution. The standout “nipple dial” variant—a highly uncommon feature on this reference—adds depth and collectability, as most examples were produced with standard markers. The combination of an annual calendar complication, a rarely seen dial, and full original condition makes this watch a distinctive entry in the vintage Piaget canon.

It represents a period when Piaget sought to compete with more traditionally “serious” watchmaking maisons by creating complicated watches that remained true to the brand’s aesthetic DNA: thin, gold, and distinctively styled.

Key Details To Consider

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.
