Power Reserve on Patrimony Traditionelle with calibre 4400

I bought the patrimony traditionelle in february of this year. This calibre is supposed to have approx 65 hours power reserve when fully wound, and I am sure it has given close to that. I hardly wear this watch, and take great care of it. It stays in its box and approx once a week I take it out to wind it. Recently I have noticed that it is giving me only 48 hours power reserve? A) why is this? Could something be wrong or broken? It has not been accidently dropped? B) could this be natural wear and tear? C) could it be lack of me wearing it? Any thoughts from loungers would be appreciated.
I can see two issues. either something is broken or you are not

winding to full capacity. I know that fully winding the 4400 is a long process and needs over 100 turns of the crown!!!

Thanks for your response.  Two questions:

a) If something were broken, would the movement still give near accurate time and have a power reserve oof 48 hours?

b) How does one know when to stop winding? I stop winding when I feel a lot of resistance, and honestly am scared to wind more because it gets to "tight". But, I don't think I did 100 turns.

something in the winding mechanism could be broken and this

has no impact on accuracy.

Maybe you can take it for inspection

Thanks.

If something broke, I wonder how? I have not dropped it.

I will try winding it 100 turns. I hope that is the problem.

How do you know when to stop winding?

you stop winding when you feel a strong resistance

Thanks.

Will try again and let you know.

just got a mail from a Lounger who has 2 Patrimony Traditionnelles who

says that he knows his watches are fully wound when the component the red arrow points to stop moving when winding the crown

KK, this happens to all self winding watches,

with power reserve.

Either you put them on a watch winder or wind them up by hand,

they never get fully wind up!

Believe me, I have several and of different brands...

among them I still have this one, even if the name is misspelled on the dial,blush

but I'm very proud of the pic smiley.

It's the same with several VC's I have or have had.

They only get full winded if you wear them constantly, for a week at least!

Good Luck yes

Thanks for both your recent posts.

- Alex, I will wind my watch tonight with a careful eye on the component at the back, and let you know.

- Doc, thanks for your insight. My watch is manual wind (same movement as 1921), and I feel it is giving me 48 hours power reserve, when it should give close to 65. Also, it is brand new. 

Doc/Alex - I have a question for you -
07/19/2011 - 12:02

- Doc's explanation is for Self-Winding watches, essentially a movement with a rotor, which gets it energy from the movement of human wrist.

- Does Doc's logic also apply to manual wind watches? In other words, when a manual wind watch is would up, does it make a difference to the

watch/movement whether it is worn or not?

I know I have wavering a bit from my original post, but this question has intrigued me a bit.

on a manual watch the fact that you wear it or not has no

effect on the power reserve

Thanks kk! Please,

read my post above.

Wear your watch 1 or 2 weeks constantly and you see it will have 65 hours power reserve.

I also noticed on nearly all new power reserve watches, that they gets a memory,

and that's why you only get 48 hours, because you have not let it wind up fully, time and time again.

This Girard-Perregaus Gyromatic, coording to Peter CDE, the Gury of GP's,

it's one of the first, keeps a quite good power reserve, if I use it for a week, which I only done one or two times.

Otherwise it soon dies. Keeps time as a new!

From 1949

Cheers
