Rolex 3135/31XX caliber setting wheels: how big an Achilles Heel?

[Adam K.]

I'm interested to learn more about the setting wheels in the 3135/31XX family of Rolex movements, which are one of the few areas that receive criticism when modern Rolex calibers are discussed. When weaknesses in these generally very tough movements are talked about it usually comes down to either A) the rotor axle or B) the 2 small diameter setting wheels (compared to the 15XX and 30XX calibers) which are prone to damage over time...and can wreck havoc on the mainplate itself if things get bad enough, apparently.

Its been said that regular servicing within recommended schedules is the big variable as to how much wear these setting wheels in the 31XX movement experiences. But, are there any OTHER factors? That is, can certain types of use or operator influence affect how much damage these setting wheels experience over the course of a 5-10 year wearing interval?


Would love to learn more from the watchmaker technicians who have experience with servicing these movements. Aside from overhauls within a recommended 4-6 year interval (approx.) are there any other helpful tips to ensure that this area of the movement is kept in reasonably good shape over the long haul, assuming one wears his/her watch more or less on a day-to-day basis?


Thanks!
