Rolex rotor question

[timuS]

Hi everyone!
A lot has been said about how the jeweled pivot perpetual rotor on the 31XX family of movements is its primary weakness. Moderately heavy shocks and not adhering to the service intervals strictly, can result in a damaged rotor axel that can be bad for the movement. My question is this - If the 31XX movements are prone to such problems, how come so many of these movements have proven their mettle in extreme situations without the need for much maintenance?

It all depends how soon you discover the damage and repair before the real damage happens. If that calibre on any other auto is hit at just the right angle with the right power the axle will break or bend enough to do damage to the plates. The metal on metal will dust up the movement and wear out gears and so forth. 3135's are very stout excellently made movements which if maintained will surely last a lifetime and then some. Rik
