Given enough time to regulate, about +3/-0 is possible for mechanical
I base that on comments from Grand Seiko’s legendary master watchmaker, instructor, and magician AKIRA OHIRA. This is for a good normal movement - no complications.

Not sure if a Grand Seiko/Credor spring drive movement is allowed to compete
as that has an accuracy of half a second a day. If disqualified then how about a Patek Philippe Tourbillon which is accurate to -2 +1 daily.,
The precision of the figures are provided
are based on the watches leaving the factory after being tried and tested. I would expect the watches to offer the same accuracy after each service at the manufacturer. Parts would only need to be replaced if deemed necessary to maintain the originality, ...
Many manufacturers like Seiko for example
have watches that perform better than the tolerances they quote. The watch would normally be tested in at least five positions and in some instances more. Arguably some watches are likely to be more robust than others. I would expect a Rolex for example t...

"was" my 50 Fathoms Bathyscaphe. On my watchmakers timing machine it was perfection in every position! He couldn't believe it. Unfortunately it had a quality control issue that I missed when I purchased it. It was nearly impossible to find the crown's win...
