When you think of Cartier, their longstanding history in Jewelry probably comes to mind. But, they also have a renowned reputation for making timeless and elegant timepieces for just over 100 years. 

The Tank Louis is without question their most well-known model, but the story doesn't end there. Beyond their Tank line are numerous executions - many produced in very limited quantities - that are quite literally some of the most beautiful timepieces ever made.

This particular example, a Tonneau model, dates to circa 1990s and features a 27 x 46mm 18k yellow gold tonneau case with a wildly cool, curved crystal, a lovely white guilloche '"Paris" signed dial with printed 'Roman' indices, a matching blued-steel 'sword' handset, and Cartiers ubiquitous sapphire cabochon crown.

This piece is powered by a hand-cranking movement and comes fitted to a signed navy blue alligator leather strap with a matching yellow gold deployant clasp.

As effortlessly comfortable as it is elegant, this piece is appropriate for virtually any wrist.

A Tank is always a winning pick — but choosing something slightly off the beaten path like this Tonneau, with its stunning curved design, signals a particularly refined level of taste.
