I’ve never seen another watch quite like this one. I’m not positive it would be excellent for telling the time – it’s sort of difficult to read – but I think being aware of the time is not the primary reason one would wear a watch like this one.
What I find so remarkable is that the face of the dial is a cabochon emerald crystal rather than something colorless and traditional.
The the bracelet is set with circular- and single-cut diamonds, and is expandable. The dial, beneath that cabochon emerald crystal, is applied with Roman numerals. Outside the emerald, the dial is bezel millegrain-set with circular-cut diamonds. The dial of the watch is signed Cartier, and was made in 1920.
