18ct yellow gold OMEGA Chronomètre wristwatch. Made 1947

This solid gold OMEGA dress watch holds the classic 30.10.RAPC Bumper automatic chronometre grade movement. A "bumper" is an early type of automatic movement. Unlike modern automatic movements, where the rotor completes a full 360-degree rotation, the rotor in a bumper moves back and forth in an arc of about 180 degrees, bouncing off springs positioned on opposite sides.
