The Pasha de Cartier is a stunning design
I love that watch and many of its different variations.
And in fact I have mine more than 30 years now, not the one in the picture and it is a timeless design.
The Pasha watch was designed, with help from Gerald Genta, in 1985.
The Pasha of Marrakesh lived in 1933.
Cartier may have designed a watch for him to swim with,
but that was not the big 38mm watch as we know it,
But probably a small square watch, like most of Cartiers watches were at that time.
