Notes

The Cartier Santos 100 Mystery WM502551 is an extremely rare and collectible timepiece. This exclusive watch featuresa squared case measuring 41mm x 41mm, crafted from 18K pink gold with diamond embellishments, weighing 171
grams.

At the heart of this exceptional timepiece beats the manual-wind Caliber 81003SC movement, which powers its distinctive «Mystery» feature – an eccentric mystery aperture on the silvered dial that creates a floating effect for certain elements.

This particular reference is highly sought after by collectors due to its extremely limited production of only 10 piecesworldwide, making it one of the rarest iterations of the famous Santos line. The watch comes complete with a Cartier fitted box and certificate.
