The Certina 919-1 watch movement, introduced in 1962, is a chronometer with an integrated winding gear. This innovative design eliminated the need for manual winding. The movement also features a detached manual wind mechanism. Notably, the sweep second hand is smoothly controlled by a magnet in a bushing, replacing the traditional friction spring mechanism. The movement supports automatic winding, sweep second functionality, and a date function that can be set by changing the 22-24 hour period. Additionally, it includes a hack feature. The Certina 919-1 movement is dated back to 1962 and offers these distinct functions.
