View source for IWC 3752

Calibre '''3752''' is an [[automatic]] watch movement from [[IWC]] produced from the 1980s through the 2000s 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 [[IWC 375|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 '''Cal. 3752''' family.

When ETA released the [[ETA 2892A2]] in [[1998]], IWC began adopting it, starting with [[IWC 30110|Cal. 30110]]. This family replaced the 2892-2 movements within a decade.
