Omega Speedmaster automatic winding: represented by the 9300/9900 automatic winding chronograph movement Speedmaster on sale. The 9300/9900 automatic chronograph movement is Omega’s mainstream automatic chronograph movement and one of the best automatic chronograph movements among mainstream Swiss watches.
The 9300/9900 movement uses Omega’s unique coaxial escapement, equipped with a silicon hairspring, and employs a combination of cylindrical wheel and vertical clutch technology (a standard configuration in modern chronographs of famous watches). The most prominent external feature is the integration of the 12-hour timer and 60-minute timer into the chronograph counter at 3 o’clock.
Building upon the original 9300/9900, the latest SUPER RACING model using the 9920 chronograph movement has been developed. The introduction of the first Spirate silicon hairspring precision adjustment device has elevated the accuracy standard of mechanical watches to an unprecedented 0/+2 seconds per day, aiming to become a global leader.
