Chronograph watch

Chronograph watch

Commonly known as "three needles and three eyes", there are also three crowns. 1. Most of the chronographs currently use the two-button type. The two buttons are usually at 2 and 4 points respectively. The 2-point button controls the “Start and Stop” function, and the 4-point button controls the “Return to Zero” function. 2. The operation method used is usually "start---stop----return to zero" or "start----stop----start---stop---return to zero". The stopwatch function must be stopped before pressing the zero button. 3. The one-button stopwatch is relatively simple, and the function of “Start---Stop----Return to Zero” is controlled by a button. Please note that each time you press the button, you must wait for the button to reset before you can press the second time.
