Depending on your levels of fluency in both French and fashion, baignoire either means bathtub or one seriously covetable accessory. The Cartier Baignoire watch — curved, elegant, defiantly unflashy — is currently having un moment. With the first iteration appearing in 1912, getting its name in 1973 and seen on the chicest of wrists in the intervening decades, the timepiece exemplifies Cartier’s dual heritage as a jeweller and watchmaker. Fast-forward to now and (as well as storming vintage demand) it’s making a splash as part of an expanded collection, with tweaked proportions and a ridiculously sleek bangle version.
