I Want To See Your Movements!

So here's the back of my Panerai Pam 00510 with the in house movement P.5000. A rather modest presentation of this movement with a big back plate obscuring most of the view. Still fairly pretty though and well presented in my opinion. But the 8 day movement is very impressive letting you wind it once a week.

I'm sorry because I am sure this is a really stupid question (if it helps imagine me typing it with a head wand).

When winding for a weeks worth of power are you having to wind it 4-5 times as much as you would a standard 40ish hour watch or is it geared so that you still wind the same amount and it just multiplies the power per wind?

Not a stupid question at all! I wondered the same thing when considering it. This happens to be my first hand wound watch! So I have nothing to compare it to, It doesn't take that much winding though, nothing unusually long I would say. But having no traditional hand winder to compare it to I cannot answer with any scientific accuracy. 

Hope that answers your query.......ish.

Longines Cal. 10L

The 27mm Weems was built to US military specification 27834 and I read somewhere that these watches could be regulated to (better than) chronometer precision - note this is an import to the USA hence 'unadjusted' on the bridge - cased and timed in America to avoid the taxes otherwise.

The R.A.F. specified the larger 34mm version, which used a Longines Cal. 12.68N,  and to Building Specification G.535 they were required to achieve +/_ 15 seconds

Still really don't know what a Gruen 731CA is doing in a Talis watch that was probably sold from a catalogue.

Think I accidentally deleted the photo.

Citizen Crystron cal 8550 from 1977, currently away having its circuits rejuvenated, at huge and probably unjustified expense. :laugh:

My 1940 Longines Weems with Cal. 12.8N. Serial number dates movement to 1939. A true WW2 watch.
34mm case & I wouldn’t have wanted to ask a Lancaster bomber navigator why he was wearing a girl’s watch!
