The **18680** is a [[tourbillon]] [[grande complication]] movement produced by [[IWC]] based on the [[Valjoux 7750]] [[ebauche]] from [[1993]] through [[2001]].

===== 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. The next major advancement for IWC was [[IWC 79091|Cal. 79091]], a [[grande complication]] movement combining Klaus' perpetual calendar with a [[minute repeater]], introduced at the [[Basel Fair]] in [[1990]]. In [[1991]], IWC released an innovative [[rattrapante]] chronograph, [[IWC 79030|Cal. 79030]], designed by [[Richard Habring]].

In [[1992]], IWC combined all of this with a [[tourbillon]] escapement, launching "[[IWC Il Destriero Scafusia|Il Destriero Scafusia]]". The watch was Ref. 1868 and the movement, **Cal. 18680**. It remains a signal achievement in watchmaking. "The Warhorse from Schaffhausen" has the following features 

  * [[Hand winding]] [[tourbillon]] operating at 28,800 A/h
  * [[Perpetual calendar]] with [[moon phase indicator]]
  * [[Rattrapante]] [[chronograph]]
  * [[Minute repeater]]

===== Applications =====
The only watch produced with Cal. 1868 was the "Destriero". Although only 125 examples were produced, they were listed for sale from [[1993]] through [[2001]].
