This platinum hand-wound watch from Patek Philippe has 10 days autonomy, thanks to a complex mechanical movement with double barrel. It also incorporates a tourbillon rotating around its own axis in one minute behind the transparent back.
Jours means days in French. The mechanical manual-winding movement of this timepiece is composed of 231 parts, 72 of which are for the tourbillon.
Certified as a chronometer by COSC and bearing the Poinçon de Genève label, the caliber provides 10 days power reserve. Made of 950 platinum, the rectangular-shaped art deco style case features a waisted profile and flanks with triple fluting. The dial incorporates small seconds at 6 o’clock and the power reserve at 12 o’clock.
