The 76061 is an chronograph tourbillon movement with perpetual calendar produced by IWC based on the Valjoux 7750 from 1999 through 2004.


The Valjoux 7750 movement was extremely important to the resurgence of IWC and the basic design remains in use today. The company has used it for many important innovations since the 1980's, including a perpetual calendar, rattrapante, and grande complication. The 7750 ebauche was used for the 790 family of movements and the basic architecture is the basis for today's 69000 family of movements. In 1985, IWC surprised the world with the introduction of an innovative perpetual calendar movement, Cal. 7906. Designed by the legendary Kurt Klaus, this movement was much simpler to operate than previous perpetual calendars and was reliable and relatively affordable as well. In 1992, IWC created a tourbillon grande complication based on the 7750 and Klaus' perpetual calendar module.

In 1999, IWC created another 7750-based perpetual calendar tourbillon, the IWC Da Vinci Petpetual Calendar Tourbillon. This watch featured this Cal. 76061, which boasted all the features of the original Da Vinci Perpetual, with the tourbillon visible through the caseback. An unusual feature was that this movement was hand-winding. The watch, and Cal. 76061, was only produced for five years.
