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 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 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 Cal. 3752 family.
