So interesting. What were those few problems with the 3135? How serious were they, how long did it take for them to be resolved? And I'm wondering if Rolex acknowledged the issue or not.

The 3135 has clearly had a long and revered history of strong performance and reliability.

88/89 is the past. We are now in the present with the 31 movement proving strong, the 32 with some problems.

Timing apps, timegraphers etc are not Rolex toys. They are proven diagnostic tools.

My K series GMT II, while not as accurate as your Sub at -1 sec per day, has run consistently since I acquired it in 2006.

Love the 16600. My favorite reference. Beautiful!
