The column wheel
The Panerai Chronograph movements feature a column wheel system, a sophisticated mechanism that guarantees the highest standards in terms of technology, quality and reliability.
The column wheel takes its name from the presence of a series of “columns” positioned perpendicularly above the wheel. Its function is to control (activate/deactivate) the chronograph levers according to the impulses received by the chrono push-piece.
These columns guide the movement of the chronograph levers which press against a column or fall into an empty space. The column wheel therefore permits two or more levers to be engaged simultaneously, which operate the chronograph functions with a single push.
This device therefore allows greater precision in the operational sequences of the chronograph. The column wheel ensures smoother operation of the chronograph and very precise operation of the chronograph functions.
The column wheel is visible on the back of the watch through the sapphire crystal window.
