This is the first combination of drum roller and analog movement into one piece module.
The analog crown has replaced to button, simplie to adjust time.
Both roller and analog are work independent, you can pre set two different region time and watch the both timing together.
As the first drum roller movement with the chrono function.
We redesign the movement program and success to use the roller to count the time.
