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

===== Details =====
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 [[IWC 7900|790 family of movements]] and the basic architecture is the basis for today's [[IWC 69000|69000 family of movements]]. In [[1985]], IWC surprised the world with the introduction of an innovative [[perpetual calendar]] movement, [[IWC 7906|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 Perpetual 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.
