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.


Beginning in 1950, IWC produced automatic watch movements featuring their patented Pellaton winding system. This series of movements, starting with 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 Cal. 854.

IWC then turned to other companies to supply movements. High-end watches were fitted with the refined and thin Jaeger-LeCoultre movement Cal. 889, now known as IWC Cal. 3254. The remainder of IWC's automatic watches used 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 Cal. 30110. This family replaced the 2892-2 movements within a decade.
