About the IWC 76061

It takes the Valjoux 7750 architecture of the 79261, removes the rotor and adds a tourbillon at 6 o'clock beneath Klaus's calendar module, which shows the date, day, month, four-digit year and moon phase and sets from the crown alone. The result is 31 mm across with 35 jewels, a 44-hour reserve and a beat of 28,800 vph, and it is the movement of the ref 3752 and of the Quattro Stagioni set of four dial-language editions. The 7750 piece explains the base.

In the library it powers 32 Da Vinci references, in yellow, rose and white gold and platinum, and every one is a limited edition; 33 of the collection's tourbillons run it.

The 79251 is the split-seconds version of the same base without the tourbillon, and the glossary defines the tourbillon and the perpetual calendar.
