Rolex. A very rare and unusual 18K gold and diamond-set automatic sweep-centre seconds calendar wristwatch with bracelet and petrified fossil hard stone dial

Among the very many different variations of the Day-Date model, the present one certainly deserves a special mention. One of the rarest iterations in the series, this timepiece sports a dial realized with a rock including fossilized specimens, clearly visible to the naked eye. Beyond the rarity of the timepiece, one has to appreciate the craftsmanship of the artisan who carved the thin slice of brittle material, and then set the diamond-set numerals onto it.
Icing on the cake is the uncanny feeling the wearer experiments when he or she realizes that they are reading time on a canvas which took millions of years to develop.
