====== IWC 375 ======
Calibre **375** is an [[automatic]] watch movement from [[IWC]] produced from the 1970's through the 1980's and is based on the [[ETA 2892]].

===== History =====
Beginning in [[1950]], IWC produced automatic watch movements featuring their patented [[Pellaton]] winding system. This series of movements, starting with [[IWC 81|Cal. 81]], was well-respected and produced in large numbers. But like other companies, IWC was unable to invest in a new movement generation in the face of the [[quartz crisis]]. So IWC's Pellaton movements ended production around [[1975]] with the [[IWC 854|Cal. 854]].

IWC then turned to other companies to supply movements. High-end watches were fitted with the refined and thin [[Jaeger-LeCoultre]] movement [[JLC 889|Cal. 889]], now known as [[IWC 3254|IWC Cal. 3254]]. The remainder of IWC's automatic watches used this **Cal. 375**, which was based on the [[Eterna]]-designed [[ETA 2892]]. As the industry rebounded and ETA introduced the improved [[ETA 2892-2]], IWC followed with their [[IWC 3752|Cal. 3752 family]].
