Sartory Billard SB04-E TANTOSTER marks a groundbreaking collaboration between Oster Jewelers and Sartory Billard, produced in an exclusive 10-piece edition that celebrates the artistry of fine watchmaking. For the first time in a production series, tantalum meets the intricate craft of guilloché, resulting in a mesmerizing dial adorned with the traditional "grand panier" basket-weave motif, a pattern deeply rooted in horological history. Every glance reveals a dynamic interplay of light across its surface, with tones shifting and textures evolving as the watch moves on the wrist, creating a sense of depth and vitality rarely seen in modern timepieces.

Ref. SB04-E TANTOSTER
Encircled by a tantalum bezel featuring a fumé sunburst finish, the dial showcases stunning detail, from its sapphire disk with diamond-polished chamfered edges to its luminous Super-LumiNova® BGW9 accents. Even-numbered diamond-cut markers contrast elegantly with the signature Y-shaped indices inspired by the Eiffel Tower, a nod to Sartory Billard’s Parisian heritage. Crafted for true connoisseurs, this rare creation stands as the world’s first tantalum guilloché watch series, a fusion of technical mastery, material innovation, and refined elegance available exclusively through Oster Jewelers.
