How to regulate P.9000 decorated A-7750

[jrs335 0]

Anyone know how to adjust the fine tune regulation on the P.9000 decorated A-7750? The adjustment lever appears to be under the decorations, hope I don't have to remove the rotor and plates.

P9000? sounds like a gun from battlefield 2..

you dont fine tune regulate unless you want to take off the bridgework...regulate via the balance assembly, just move a cunt hair whichever way you need to adjust for

I'm confusticated here. Surely that photo shows the balance wheel with clear access to regulate time and beat.

[Cynikal.Mindset 1]

the movement pictured has access screws the 2 blue ones on the balance assembly which you would remove to gain access to the fine regulator, some other variations of the decorated 7750/p9000 have a solid plate that covers the whole balance like so

So can't it be regulated by the arms visible in the gap?

[Cynikal.Mindset 1]

yes, that would be what is considered coarse regulation

...if it's 7750 based, use these pics as a guide...but be aware, only move it a midge's dick at a time, wear it, observe any improvement and adjust further as necessary...

 

 

...if memory serves it's this way to increase,

I have a timegrapher but that coarse adjuster moves the setting too much in either direction. I need to get to the fine adjuster lever but it is covered.

is yours a version with solid plate over balance or 2 piece plate with the 2 screws?

the 2 blue screws on the balance decorative cover once removed should gain access to the fine regulator (if they left it in place during the modification)

I will try that later but it looks like the whole piece might be one plate (polished w/2 blue screws and brushed plate beneath it) I tried removing some screws and they appear glued down!.

[Cynikal.Mindset 1]

it very well may be a solid plate with a polished section and it wouldn't surprise me if they used an adhesive of some variety either...how much is it off a day?

It's off about -8 seconds/day

[sconehead 5]

-8 seconds...I'd leave it be mate...if you take it off at night, put the watch face up and you might regain a second or three...

I know, but it wouldn't regulate the movement.

[jrs335 0]

I think I'll leave it alone until someone else tries it. I love this watch too much to mess it up!

Bring it to a friendly watchmaker, he wil do it.

don't say that... soft to hard would be the perfect micro-adjust.

 

Scones pics show exactly how to adjust the movement, though -8 is pretty damn good. It's a bit of a fools errand trying to adjust out 8 sec on an unserviced A7750, but if I was going to do it, I'd do it via the balance area-
