WAtER RESIStAnCE
Your BRISTON watch is water-resistant to 20 bars. The water-
resistance of your watch is identifiable by the symbol 20 ATM
engraved on the back. This means that your timepiece has
been tested at an overpressure of 20 bars, corresponding to
an immersion pressure of 200 meters (1 bar = ~10 meters).
In order to guarantee the durability of the watch’s characteristics
over time and as the water-resistance may be affected by
certain activities, it is recommended for the user to:
> have the water-resistance of the watch checked by an
authorized BRISTON dealer, and in the event of any case
opening, it is recommended for the test to be carried out with
increased air pressure,
> check when purchasing the watch that the strap or bracelet
is suitable for the intended use,
> avoid subjecting the watch to excessively abrupt temperature
changes,
> protect the watch from being dropped or suffering other
shocks (please, have the watch checked after any violent
impact),
> avoid the use of the controls, time-setting crown while under
water or before the watch has dried after immersion,
> restore & screw-back the time-setting crown to its normal
position against the case after every manipulation,
> rinse the watch with fresh water after any use in seawater.
Please also note that leather straps are not suitable for aquatic
activities.
Furthermore, it is vital to have the water-resistance of your
watch checked by an authorised BRISton retailer at
least once every two years, and before any period during
which it is liable to undergo prolonged and/or regular
immersions.
