Patek Philippe 10 Day tourbillon

This masterpiece from the workshops of Patek Philippe Geneva is the first watch that combines two complications which are very difficult to accommodate in such a small space: two mainspring barrels connected in tandem for 10 days' power reserve and a tourbillon which rotates about its own axis once a minute and can be viewed through the sapphire crystal caseback.

Patek’s Ref. 5101P has a double-barrel movement that ensures a 10 day power reserve for the Tourbillon. It is a manual-wind movement, Caliber 28-20/222 with COSC certification and the Geneva Hallmark.
