On very rare occasions, it may happen that the analog hands go out of sync with the digital readouts.
This can be, for instance, the result of a shock on the watch.
The problem can occur to the seconds' hand only, but may also apply to the other two hands.
Fortunately, the B-1 offers its owner the ability to easily correct this kind of discrepancy.
This method is the same for all other models equipped with the B68 and B78 calibers, like the
Chronospace (2010) and
Re-syncing the time
If the hands are not in sync while showing the time,
please follow these steps to get the hands ticking back in unison with the LCDs:
First, make sure that the LCD time is properly set.
Indeed, the hands' time has to follow the LCD time, not the other way around.
To do this, go to the “TIME” mode, and set the time according to the usual routine.
Put your watch in the “blank” mode
(between “TON/L” and “TIME”, recognizable with both blank LCDs).
Pull out the crown.
The sweep second's hand should now go straight to the top (at the 60 seconds mark, if properly set) and stay there, while the number of seconds is also 00 in the LCDs.
The top LCD displays “R” and time has stopped in the bottom LCD, so that you can set the synchronism quietly.
The hours are blinking in the bottom LCD.
If you need to set the hours' synchronism, twist the crown accordingly until the analog hour hand matches the LCD readout.
Press the bottom pusher to go on to setting the minutes' synchronism.
Do likewise until the minutes' hand matches the LCD minutes.
Please note that this hand can be set in half-minute increments.
Finally, press the bottom pusher to go on to setting the seconds' synchronism.
Do likewise until the seconds' hand matches the LCD seconds.
(Please note that the seconds' hand can only turn clockwise,
so you will have to complete a full revolution if you go past the correct position.)
If you are unsatisfied with your settings, you can press the bottom pusher once more to go back to setting the hours.
Push the crown back in place.
Once the crown is pushed, the watch will go to the “TIME” mode, and will display the current time
(i.e. it will “jump forward” to the time it is now, not the time which was displayed in the LCDs while you were setting the analog-digital synchronism).
Re-syncing the chronograph
A separate procedure exists if the seconds' hand does not reset properly at the 60 seconds mark in chronograph mode (“CHR”).
In this case, simply pull the crown and set the hand to the correct position.
