every immersion in sea water. It is also advisable to have the water-resistance
of your watch checked every two years. To guarantee service in compliance with
brand requirements, any work on your watch must be carried out by the Bell &
Ross repair centre or a Bell & Ross-approved watchmaker. You should present
the Bell & Ross warranty card, duly dated and signed by the retailer when the
watch was purchased, for any work within the warranty period.
