The cleaned components are dried, after which the movement is entirely reassembled and lubricated.
The watchmaker makes the first adjustments to the precision of the movement according to the brand’s accuracy criteria.
After casing the movement, the watchmaker measures its chronometric precision once again and makes any final adjustments necessary for it to meet Rolex requirements.
The case back is then screwed down, and your watch undergoes another Rolex-specific test lasting at least 24 hours to verify the performance of the movement over time.
