The Elgin 288 watch movement is a manual wind movement with sub second functionality. It was used during the period of 1936-1944. Some notable features of this movement include a Breguet hairspring and short edges that can be straight or curved. Additionally, there is an option for an optional cover plate and raised hands for strongly curved dials. The movement is partially derived from the ETA 735, although the differences between the 7AN and 7AP variants are not specified.
