After similar one-off pieces dedicated to the Wat Arun temple in Bangkok, and the Grand Prix de Monaco (both 2016), Ateliers deMonaco have presented the Tourbillon Casino de Monte-Carlo. A single piece depicting the Montecarlo casino on the dial, powered by the brand’s tourbillon movement XP1. I had imagined that this sort of watch was made to order but apparently not: at the time of writing, the watch is still for sale.

The dial, also in white gold, comprises three plates at slightly different heights to enhance the three-dimensional effect, one at the bottom with the opening for the tourbillon and also showing the Casino steps and palms, the next for the building, and the third for the sky. Hour markers are applied to the dial, and their lozenge shape reflects both the company logo and the Monaco coat of arms.
