Chrono 4 is the first chronograph in the history of watchmaking whose counters are arranged in a row.
It is a real innovation both aesthetically and functionally, and it is a real revolution also from a technical point of view. Never before had a dial with counters (minutes, hours, 24 hours and small seconds) placed on the same horizontal line. A graphically cleaner and more logical layout.
In addition, the mechanism of this chronograph "works" with 53 jewels. Chrono 4 is a self-winding mechanical chronograph, with a steel or rose gold case resistant to water up to 50 meters, has a curved sapphire crystal, screw-down crown and caseback closed by 8 screws.
