Chronograph
- 31/08/2011
A Chronograph not only shows the time of day but also includes a stop-watch facility for measuring a time interval and displaying it with a dedicated seconds hand, together with elapsed minutes and hours often shown on sub dials.
The Breitling Navitimer World pictured has a push button at 2 O’ Clock for starting and stopping the stop watch and a push button at 4 O’ Clock for resetting the stop watch hands and sub dials.
