* highly jeweled 8-day movement * the hours indicated by a star with a large brown diamond, attached to the revolving dial enameled translucent pink with spreading rays, the minutes indicated by an orbiting smaller diamond-set star operated by a hand concealed behind the dial * Roman numerals to the gold and white enamel chapter ring, bordered by rose-cut diamonds, three lacking, diamond-set florettes at the corners, rock crystal strut * movement signed Longines, hand-stamped reference numbers 383 to the winder * original presentation box signed Cartier

The movement is running, however it might require service soon. The dial appears to be in nice condition with no hairlines or damage. The brown diamond is approximately 1.05 carats, slightly orangey brown. There are three diamonds missing surrounding the enamel bezel. The rock crystal surround is generally in clean condition. There appears to be a natural defect in the rock crystal near the bottom right corner and there is a small chip to the back bottom left edge and an abrasion to the edge of the right back bottom. The red Cartier box is in nice condition, however the handle is slightly cracked and in danger of breaking. Overall this is a lovely clock.

The present lot is a variation on the famous Mystery clocks by Cartier, and can be compared with the Comet clocks, which operate on the same principle.

Longines confirms production of movement number 2978641 and its sale on 16 December, 1920 to Pérusset & Didisheim, their retailer with offices in Paris and Buenos Aires.

Our research has found that a similar 8-day movement, Longines' cal. 1941, was also fitted for another important Cartier clock sold at Christie's Geneva, 20 November 2008. Longines confirms production of that movement, number 2978627, and its sale 23 December 1920 to Pérusset, just one week following the sale of the movement in the present lot.
