+ Cartier Vintage 1990s Baignoire 18-karat Gold Diamond Watch, Ref. 1920 (6.25'' Wrist)

Cartier’s 'Baignoire' timepiece traces back to a 1912 commission for Grand Duchess Maria Pavlovna, its elongated oval form breaking conventions with a case designed to follow the wrist’s natural curve. Sourced by Stephanie Windsor, this 1990s 'Place Vendôme 1920' model is crafted from 18-karat yellow gold with a pavé diamond-set bezel framing a white dial detailed by Roman numerals and blued hands. Powered by a hand-wound movement, it’s fitted with an articulated gold bracelet that reinforces its high jewelry appeal.
