PAM 390 Help

[Boominferno]

Hi Guys,

I just received my Pam 390 Noob Version with the 6497-2 manual movement. I was wondering if anyone here knows what the power reserve life is on such a movement when it is fully wound?

Also, could someone tell me how am I to know when I have fully wound the watch? Is it when I am trying to wind it and the crown bounces back a little after I wind it forward?

I ask cause I wound like lightly for about 10-15 rounds once I got it delivered and the power died just after 10 hours. Did I not wind it enough?

Lastly, is it just me or is the movement pretty loud, a lot louder than the 7750 auto movement.

The crown bouncing back is perfectly normal. You'd have to wind the watch until you feel resistance in a sense that it doesn't want to wind or click anymore. You'll know it when you get to that point and that's when you should stop winding.

Thanks for the feedback. Does that mean you still wind it even when you feel the crown bouncing back but stop only when you start getting heavy resistance?

i would like to suggest dont wind till it wind no more,

Here i show u my own research over winding and power reserve
http://forum.replica-watch.info/vb/showthread.php?t=141315

for that thing that bounce back when u winding it, its normal
just keep wind, until u satisfy. but again, IMO dont wind until u fighting over the resistance.
for my 6497-2, i usually wind it about 24 x 360° in 1 day = 22-25hr power reserve

analyze ur own watch, and determine how many winding does it need

Thanks for the info. Your thread really helped. I wound it for 10-15 times (fully rounds) and it lasted for only 10+ hours. I wasn't sure if this was normal but based on what you are saying I guess it is. Perhaps I'll have to wind it 25 times each time I want to use the watch. Much appreciated.

See, its easy since u know
enjoy ur toy and oh yeah pics please

Hah. Let me try and get one up when I get home. =D

One completely good wind would last 72hours but you could run the risk of overwinding it and damaging the crown.

I can easily get about 50 half-turns on my 390. About then you start feeling it getting a little firmer so you should stop. In excess of 50 hours is easily averaged...

Great. I will probably have to trial and error with the watch and see how long it lasts. Good to have a few starting points.

Anyone feel that the movement makes relatively louder noise compared to an auto 7750 movement?

No. The gen movement is rated only for 56 hours. You would not expect the rep movement to exceed that. And to the second statement, probably no as well. When you overwind a watch, you will break the main spring. Then you will feel no resistance when you wind the crown. That is probably what you call damaging the crown, but the crown isn't the damaged part, the main spring is.

So a manual pam with full wind can only last for more or less 24h ? Tomorrow have to rewind again?

Boom, Where do you think the noise comes from? From what I knew, noise from 7750 comes from the rotating rotor, since manual does not have rotor, what could possibly make noise out of it ?

FWIW, I've constantly wound every 6497-based movement I've ever owned - ETA, A6497, gen Panerai movements - until you physically couldn't wind it anymore and never experienced any ill effects.

You should absolutely get 2+ days out of a full wind of any decent A6497, most folks see around 60hrs of PR. ETA 6497-1 movements have a slightly lower power reserve, but should still be near 48hrs, IIRC.

60 -70 half turns for me and then you're going for more than one day...

Well from what I read here, looks like there are two different opinions on PR of 6497. One is arguing around 24hrs, another is arguing around 2days+.
That is certainly a lot of difference.

Always beeen ~2days PR for me.

I am not too sure myself but it sure is loud. Perhaps someone with more knowledge can share some light?


btw, I gave mine around 50 turns on the 2nd day and it lasted about 30 hours. Perhaps 50 turns isn't the max it can take.

Nope. If you read the comments about 24 hours, they specify the number of turns (48 half turns (24x360) and 60-70). I've wound my manual winds (PAM318, PAM372 non-SC, PAM360) until the crown stops (I don't count) and they've all given me 48-56 hours PR.

Exactly.

I agree with mysterio
