If a movement has a technical issue, e.g. too much friction at a specific place, then the amplitudes will decrease quicker than Rolex designed for. If you don't compensate this effect by frequent windings, then the amplitudes enter after some time into a critical region (approx. < 200 degrees) and the rates will become worse, i.e. rates get more and more negative (less accurate). This unwished friction continues with time and significant wear will further degrade parts of the movement, hence your watch gets more and more inaccurate.

So,the reported lack of lube on the bearing and second hand pinion friction and wear should be the explanation on the 3235s affected with low amplitudes and very slow running ?
Any other reasons in a movement that can cause the low amplitudes and time loss ?
