The name "Montre Baignoire" translates to "bathtub watch" in French, referencing the watch's distinctive elongated oval shape, which somewhat resembles a bathtub.

The 1912 design of the watch that would later be christened the “Baignoire” demonstrated Cartier's prowess in crafting watchmaking forms. An elegant ellipse uniquely forged in a single line, the “Baignoire” watch is the essence of Cartier style: an unmatched marriage of purity and timeless chic.
