«The update [in 32xx] was a change in ball bearings for the rotor and a change in text engraving on the bridges and rotor. It has nothing to do with the issue that people are experiencing.
Even the 31×× got updated last year, every mainspring now has to be a complete barrel change during service, the new barrel has an extra 2 hours of power reserve.
Daytona 4130 barrel also changed, no seperate mainsprings available anymore, same goes for 22××, all of these movements now get the barrel from the 2236 with more power reserve when you get a service.
Parts for movements get updated all the time, even in older movements. In recent years the 15×× (yes an over 50 year old movement) received a 'quiet update' where the escape wheel anti-shock got updated to Kif anti-shock, which is easier for the watchmakers to work with than the old spring (which was an absolute pain in the..)
There's many more of these updates, and aside from watchmakers like me most people will never know of them.»
