I heard, if you lean a mechanical watch against the crown it will accelerate the movement, the other way around it will slow it down.

in what range could the variation be?
And am i right, that it wouldn't have an effect on how the watch is running while on the wrist, or would it be possible to adjust a watch like this?

quite large there's a thread somewhere on this....
crystal up gains a few secs, crystal down losses etc etc... it can be quite a large variation
this is why high end watchers are 'adjusted in X positions' where X is anywhere from 2-5.... the positions are these positions we are talking about....
you move your wrist so it doesnt matter but this is what a toubllion is for!
just another quick question: up to how many seconds/day gain or loss would be tolerable for an A7750?
I would say anything under +20/day is acceptable... under +10 is exceptional.
Remember B&Rs gens only are regulated to +10/day

da urban myth
stiff loves debunking da urban myth:
If da watch is compliant to even COSC's minimal standards but da hairspring is not "fully" adjusted for dat particular installation by da master "springer" the rate "may" be affected by da position. But da better watches are going to exhibit similar rates in all positions - dat's why they are da better watches (dat and da cosmetic appointments and da complications).
However, if you got a watch dat ain't so good - da comparative positional rates will vary more.
Meanwhile, back to da crown. If da escapement on one watch is offset 90 degrees from da next and one of dem exhibited a particular lack of adjustment in a specific plane, wouldn't it follow dat all things being equal dat da same type of error would be offset by dat same 90 degrees in da second watch?
Now dat dat's all as clear as mud, here's da "take way":
You can take da cheaper movements and adjust da hairspring and tweak da escapement and alleviate much of da positonal error. stiff has done this on even da 2813 and eliminated much of da positional variation.
Just like people - you can't generalize very much about broad groups of uhren.
Dis is da stiff muckler!

yes, crown up/down face up/down thing is true. It is even part of the Rolex servicing papers you get every time you get your gen Rollie in for servicing.
I had my gen Omega timed on a vibrograph watch timer and each position the watch was in provided a different accuracy.
On my other gen Omega, I could place it down a certain way each day at the end of the day. After one month of continuous daily wearing, it was out by +2 seconds, all due to the way how I placed the watch overnight.
I thought this was common knowlege amongst watch affincionados. . .

It must take more effort to think how to write 'street' than it does to actually write properly...
Dis street chat iz doin me ed in bruv - speek lyk wot da queen duz, innit.
(Not to mention english is not the first language to what must be a large number of people on this board, so if you start writing in some incomprehensible drivel, no-one will understand what the **** you're going on about and soon stop reading your posts...)
I need more chav talk in my life, please ship some of them over to NYC
