Asian 7750- winding

[Paneriwc321]

Hi all,

To start off, im not quite sure if this post belongs in this subforum...please bear with me,

I know this topic has been chewed through quite thoroughly, but it always feels better and is more of a relief when one's own question is answered directly.

I have a A7750 chrono (standard; secs @ 9) for around 2 months now, don't wear it all day/everyday. Whilst on a day i dont wear it, and the time is still running, i tend to hand wind it 10-20 rounds at night, just to keep it going and not have to worry about when i can set the date/time if it stops, you know, the whole 9 yards. When i Notice that it has stopped, i hand-wind it approx. 50 rounds (never feel any resistance). I wouldnt say that i wind it aggressively, but not quite slow either.

On days i wear the watch, which is 2-3 times a week, i do not wind, since i rely on the rotor to do its job.

Now i have read a few articles/posts, saying that fast and aggrssive winding can cause "teeth" of a certain wheel inside the movement to grind down, or even break off. Source: http://www.rwg.bz/board/index.php?showtopic=1613

So, what do the movement experts say? 2 months of the aforementioned use- have I already damaged the movement? If so, how do i notice it, without having to open the caseback (since i dont have the necessary tools for that )? And what is the runtime of a fully wound 7750?

Feel free to call me paranoid- at least then i know that all is well

Much appreciation for any comments/help/ideas!
