LONGINES AVIGATION MONO-PUSHER CHRONOGRAPH TYPE A 7

LONGINES AVIGATION WATCH TYPE A 7 is a single-pusher chronograph, which uses only one button to start the chrono function, to stop it, and to reset it to the zero position.

An elegant black dial is enclosed in a case under the right shift in the 50-degree angle.

A classic chronograph, in contrast, has two push-buttons, one to trigger the function and the other for the reset.

Single-pusher chronographs are very rare, because they're mechanically more challenging, since a single button is co-axial with the winding crown.
