Ok guys. I returned a Pam 252 a few months ago for two issues which I posted on here before. One was the W for the west designation fell off the bezel the second was a strange loss of time every half hour. I was given a replacement watch and figured I would test it out today. So I set the watch gave it a few winds until it was functioning and then slapped it on the wrist. I checked the second hand accuracy against a stop watch and it was dead on. I set the time and everything seemed fine. It has been on my wrist since 0600 hrs this morning. It was keeping perfect time or close to it all day. Now suddenly it is approximate 8 minutes slow. I don't get it. This seems to be the same problem the last one had. The movement is an A-7750. I don't understand how it can be keeping accurate time for three hours then suddenly drop 8 minutes all while being on the wrist. Any help? Should I send it somewhere? It was already tested prior to shipping out.

A little update...I took off the watch and the movement has stopped all together after about 30minutes. Could the movement not be storing any reserve power?
Any one?

This sucks...I just got it yesterday. I thought it was gonna go just fine but it doesn't seem to store any reserve power.

Just let it run dead and picked it up. Started giving it a little shake for about a minute and the second hand starts up. So that would lead me to believe that somehow it does not keep stored energy.

You have 2 options:

- pay to ship the watch back
- use that money to get the watch checked, and hopefully repaired by a watchsmith.

Where are you from?

Katt and G. are in the US and could take care of your watch.

It's up to you, either sending it back or get it fixed locally. Both options are valid if you ask me.

whoa whoa...hold on! don't send it back yet.

So I set the watch gave it a few winds until it was functioning and then slapped it on the wrist................... I don't understand how it can be keeping accurate time for three hours then suddenly drop 8 minutes all while being on the wrist. Any help?

Give that bad boy about 50 good rotations of the crown. That will give your mainspring a good reserve. Wearing your watch for the day, especially 7750 as the rotor only winds the barrel in one direction, will just keep the power reserve up, not wind to the max.

Sounds to me like a simple missunderstanding. Let us know what happened. :)

Don't know about the asian version, but it's usually not recommened to hand wind a swiss 7750.

Good point Wiz. It's usually not recommended cause some people treat ultra miniature gears like a semi-truck transmission! :) Just do it really slowly and carefully......... Or buy a watch winder and leave it on there over night.

Yup, I've always been told to be really carefull hand winding a 7750. A few turns, and only if that's absolutely necessary.

Yeah I go really slow. I probably turned it approx 20-30 times now. It seems to lose any where from 7-10 minutes every hour. Could it just be running slow and need to be adjusted?

Ok taking Frigpig suggestion I put 50 spins on it slowly. I set it at 6:30 pm which is what my phone says time wise. I'll up date ya in and hour to see were we are. Thanks everyone. This is the second north pole that's done this to me. And yes I have numerous 7750s so I'm not that clueless.

No Owen...I live near LBI. I just got this one from Lay at replicamake. This is my second one. Ok the time on my phone says 7:30 an the Pam reads 7:28 so that is a significant improvement but still seems slow.
