I know from bitter experience that hand winding an ETA 2824 movement regularly will cause major problems with the reverser wheels jamming prematurely. I've had several of these movements and each one died in approx just under one year after hand winding daily (I rotate my collection and don't use a winder). My 3035 and 3135 equipped Rolex have endured several years of regular hand winding with no user-visible adverse effects so far.
How resilient is the Patek wig-wag setup to hand winding? I've tried in vain to get either an exploded diagram or more detailed explanation of exactly how it works and I'd love to know more about the finer points of this mechanism. It's the unseen things like this that really set apart the different calibres by high-end manufactures.
Many thanks
John
