Clad in mother of pearl front and back, the Jaquet Droz Grande Seconde Tourbillon Mother-of-Pearl is equipped with an unusual movement: a self-winding tourbillon calibre with a seven-day power reserve.

The 39mm red gold case is set with diamonds on the bezel and lugs, while the dial is white mother of pearl. It’s laid out in the figure-of-eight style that’s a signature of the Grande Seconde, with an 18k red gold ring outlining the sub-dial for the time and the tourbilllon at 12 o’clock.

Thanks to a clear sapphire bridge on the top, the tourbillon is entirely visible and resembles a flying tourbillon, though it is a conventional construction. And as is increasingly standard on Jaquet Droz watches, even the entry-level models, the movement has the hairspring and pallet fork in silicon, a material favoured for its non-magnetism and precision shape.

On the back the theme is continued with the 18k red gold rotor that is also inlaid with white mother of pearl.
