Famed for their iconic collections and classical styling, French jeweller and watchmaker Cartier hold a vital position within the horology industry. However, one such collection that flies under the radar is the Ceinture, first launched in 1927 but reintroduced to Cartier's line-up in the early 1970s, around 1973. First offered in two case sizes, 25mm and 27mm, until a larger 31mm variant was introduced later, the Ceinture is a dynamic timepiece known for its unique twist on the Tank’s design. Powered by the manual wind cal. 78.1 movement, the model we have here is perhaps the variant that speaks to Cartier's jeweler-inspired ethos with a two-tone case that swaps the typical stainless steel and 18kt yellow gold combination for 18kt yellow gold and white gold case. Further speaking to Cartier's design language, it also boasts a bright white dial featuring black Roman numerals, a railroad minute track and blued steel hands. Of course, the Ceinture's most distinctive element is its unusual octagonal case. Somewhat reminiscent of a belt's buckle ('ceinture' means 'belt' in French afterall), the Ceinture resembles a square that has had its corners cut, which in turn allows the watch to wear more prominently on the wrist than one would assume judging solely on its dimensions. With its deep-stepped bezel design, the Ceinture is truly an interesting timepiece on the wrist. Feeding into this intrigue is the Ceinture's octagonal crown, which sits within its case and acts as an extension of the stepped bezel. Cartier also decided to forgo their signature sapphire cabochon crown so that the Ceinture's crown could sit within the bezel, a feature that Cartier calls "remontoir imperdable" (captive winding).

Blending Cartier's classical design language with a unique case shape, the Ceinture merges the Tank's elegant rectangular design with the Santos Dumont's angular construction in what is an abundantly clear expression of their renowned free-thinking creativity.
