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

The Cartier MONTRE BAIGNOIRE 1920 watch pays homage to Cartier's design heritage, especially their Art Deco and Art Nouveau influences from the early 20th century. The 1920s was a period of significant artistic innovation, and Cartier's designs from that era are characterized by geometric shapes, bold lines, and a strong sense of elegance and luxury.
