Ever since its debut in 1985, the Pasha de Cartier watch has moved with the times, returning in multiple guises. It owes its success as much to its unique design as to its precision mechanics. Appearances first: a square inside a circle, in this instance accentuated by the second circle of the Tourbillon. The "chained" crown – a removable crown cover attached to a chain-link – is another signature element of the design. Then the movement: this Pasha in pink gold is powered by an in-house manually-wound calibre, the 9466 MC Tourbillon Skeleton, that provides a comfortable 50 hours of power reserve. Last and by no means least, the QuickSwitch system means straps can be swapped out in one simple move and without special tools.
