This is very useful thread, so thanks for posting it up.
The only thing ‘missing’ is the length of ownership (which would obviously add a huge layer of complexity to collating the data and probably isn’t practical to capture here).
The only reason I say that is that I’ve noticed a few guys saying they have no issues on a watch that’s only a couple of months old, which is obviously great news, but mine was also incredibly accurate for a full 18 months before it started losing time. That seems like the common observation. If the issue IS adverse wear on the seconds wheel pinion, that will only come with time as (as we know) Rolex regulates their watches from the factory, so you’d expect great accuracy to start with.
Either way, I think this is an important thread and the more contributors we get the better.
