====== IWC 852 ======
Calibre **IWC 852** is an [[automatic]] watch movement from [[IWC]] in the [[1950s]].

IWC advanced rapidly in automatic movement production, introducing their [[Pellaton]] winding system in [[1950]]'s [[IWC 81|Cal. 81]] and enhancing it in [[IWC 85|Cal. 85]] and again two years later in this Cal. 852. A similar model, **Cal. 8521**, added a date complication. It was replaced by [[IWC 853|Cal. 853]] after [[1958]].
