UNIMATIC’s Modello Tre is a mecha-quartz chronograph, offering a 300-meter water resistance. All chronograph operations, though, should not be performed when underwater. To use your watch’s chronograph function, unscrew the two pushers by rotating them downwards until they are all the way out; press the top pusher, in order to start the stopwatch, the second hand will start moving across the dial and the left minutes subdial will move accordingly. Pressing the top pusher again will stop the chronograph and pressing it a third time, when the chronograph is stopped, will start it once again. If you wish to reset your chronograph back to zero, simply press the bottom pusher, and the hands will immediately return to the starting position.
It is very important to remember to always screw down the pushers whenever you are not using the chronograph function, in order to help to maintain the proved water resistance. Please be aware that the second hand is dedicated to the chronograph function, it will not move if the chronograph function is not engaged.
