Object description

Case and Gem-Setting

The watch is constructed with an 18k white gold case measuring 40.5mm in diameter. The exterior of the timepiece is set with 99 baguette-cut Top Wesselton diamonds, which provide significant coverage across the bezel, the lugs, the case band, and the crown. The total weight of these diamonds is estimated at approximately 11 carats.

The case back features an exhibition aperture, allowing visibility of the rear of the skeletonized movement, with the reference number and serial number engraved onto the metal rim.

Movement and Dial

This watch is powered by the manual-winding Calibre 711. The movement is fully skeletonized and features comprehensive hand-engraving on the visible bridge components. A tourbillon carriage is mounted at the 6 o'clock position of the dial side.
