Glossary

A complication that allows for the measurement and recording of two events simultaneously but with different durations. When the chronograph seconds parts are activated, both chronograph seconds hands start moving together. By utilizing an additional mechanism, typically controlled by a pusher (button), one of the hands can be stopped while the other continues its motion. This enables the measurement of a separate time interval while the main hand continues to track the overall elapsed time. Once the secondary timing is complete, the stopped hand can be synchronized with the main hand to resume tracking together.
