Cartier Calibre de Cartier two-tone 18K rose gold and stainless steel automatic watch, reference 3389, featuring a silver Roman numeral dial with outer minute track, small seconds subdial at 6 o'clock, date display, 27-jewel automatic movement with exhibition caseback, and two-tone integrated bracelet. 42mm case.

Complete with original box and papers.

The Calibre de Cartier's most immediately striking design element is its bold circular architecture — the large 42mm case is dominated by a prominent round brushed rose gold bezel that frames the dial like a porthole, creating a strong, masculine silhouette that positions this watch firmly in the luxury sports-dress category. The silver dial balances the bold outer form with a classically restrained layout — Roman numerals, fine outer minute track with Arabic five-minute markings, a small seconds subdial at 6 o'clock that adds complication interest without visual clutter, and a date display integrated at 3 o'clock. The two-tone integrated bracelet — stainless steel outer links with rose gold center links — mirrors the case's two-material construction and gives the watch a seamless, architectural continuity from lug to lug.

The Calibre de Cartier was introduced as Cartier's statement piece in the men's luxury sports watch category — a category historically dominated by Rolex and Patek Philippe — and immediately established itself as a credible and aesthetically distinctive alternative with its bold round bezel architecture and in-house automatic movement. Cartier, founded in Paris in 1847 and known primarily for jewelry and dress watches, demonstrated with the Calibre that it could compete at the highest level of mechanical watchmaking, producing a movement of 27 jewels with small seconds complication that was entirely developed and manufactured in-house. The reference 3389 in two-tone rose gold and steel represents the most wearable and versatile configuration of the Calibre — the rose gold bezel provides precious metal prestige while the steel bracelet ensures the watch transitions effortlessly between business and casual contexts. Complete with original box and papers, this watch represents exceptional documented provenance and full collectibility.
