Jaquet Droz's Tourbillon Skelet Sapphire features a water-resistant, all-sapphire case without a single screw, making the movement look as if it is suspended in mid-air. To add to this, immaculate hand-finishing makes the timepiece a delectable timepiece.

Furthermore, the manufacture presents customisation options for the hour markers, hour, minutes and seconds rings, hands, and the colour of the strap, movement screws, crown, logo, folding clasp, oscillating weight and engraving.

Now, Jaquet Droz is adding the ability to choose even the colour of the sapphire, with green, blue, or yellow, now added as an offering.

Each collector can also combine their selection with a variety of precious stone settings of their choice on the bridges and hour markers.
