The Alpina 753 watch movement, manufactured around 1950, features specific modifications by Wyler. It incorporates the Wyler-Incaflex shock protection system, which utilizes elastical spiral balance spokes. Additionally, it includes a disc-shaped lever bridge and nose at the train bridge to limit the spring travel of the balance. The crown wheel bearing is designed with three screws instead of one center screw. The movement offers manual winding functionality and displays a sub-second dial.
