IMPORTANT

Magnetic fields. Magnetic fields can adversely affect the accuracy of your
watch. Also, we would recommend that you avoid placing your watch near
electronic devices that may generate large magnetic fields (radio, smart-
phone, television, computer, tablet, loudspeakers etc.).
Water resistance. Once the watch is set, to ensure perfect water resist-
ance, push the crown back to position 0. Never operate the crown under-
water.
Note: The 4 slotted screws (F) mount the bezel to the case and ensure the
water resistance of the watch. To benefit from the Bell & Ross warranty,
these screws must never be unscrewed.
MAINTENANCE
After being immersed in seawater, it is recommended to carefully rinse
off the watch and strap with fresh water. It is also recommended to have
the water resistance of your watch checked every two years. To ensure a
service that meets the brand's exacting standards, any servicing of your
watch must be carried out by the Bell & Ross service centre or a watch-
maker approved by Bell & Ross. Whenever repairs are made during the
warranty period, you must present the Bell & Ross warranty card, duly
dated and signed by the retailer at the time the watch was purchased.
We thank you for the confidence that you have shown in our
brand and we hope that your Bell & Ross watch meets with
your complete satisfaction.
