This may seem trivial, but too many watch owners tend to forget it. An automatic watch like the Rolex sky dweller should be serviced by a licensed professional on average every 3 to 5 years. Yes, a watch can run longer, sometimes up to 20 years or more, some will tell you, but the majority of manufacturers advise regular overhauls.

When sent for servicing, the watches are entrusted to professionals who take care of everything with the utmost care and attention to detail. Each brand offers its services and has its procedures and working methods. But overall, these are some of the main steps in a complete overhaul:

Mark. This is the case for the moving parts and those of the case and those of the bracelet. In addition to these replacements, all the parts that need them are lubricated. This limits the effects of friction and wear of parts, which are extremely thin and fragile.
