p.9000 running fast

Could you give me a link to the one you got (assuming you are happy with it)?

My rotor does not turn that freely...it is what I would call jerky in it's movements and it makes a pretty loud sound when it turns (like a small ratcheting sound)

It's because the watch is wound. That's the sound of the P.9000 !

UPDATE: So, after gaining 2 minutes over the weekend and doing it in a fairly erratic fashion (ie 5 seconds in 15 minutes), I decided that I would bring the watch back to the store to send back to PASC. However, before I did that I thought I'd check and see if the RSC (which is in the same building) would mind checking if the watch was magnetized. They said no problem at all, checked and came right back and told me it was completely magnetized, demagnetized it, and then confirmed that in the HH position (horizontal dial up) it was running ~1 second fast per day :-)

Very cool... Although surprising RSC would do that.

I just had a watch go through a complete service there and I've taken my watches to them many times over the years. I told the watchmaker who came out to help me that they'd previously demagnetized my GMT IIc (which I was wearing) and asked if they would mind doing the same for my 305. He said it wasn't a problem at all (and I think he was sort of curious to check out the in-house movement). Anyway, it was above and beyond and I really do appreciate them having done it. As always, RSC San Francisco remains a class act.

Sounds like you may need to trade in your 305 for the 389 Anitmagnetic and your GMTIIc for a Milgauss.

I really like the 389...I could live with that trade --but I have never liked the Milgauss...that's one watch from Rolex that does not speak to me at all. My GMT keeps amazing time. It didn't lose a second during the second and third years that I owned it. I literally didn't have to touch it aside from daylight savings time for 24 months. Even now it's variance is less than a second a day and it passed the pressure test RSC did for it (for free) while I was waiting for the Panerai.

It was so obvious.
You should have try to demagnetized the watch in the first place to save yourself from all that fuss.
Imagine if the RSC have said that we can't touch a watch from another brand. Then you would send the watch back to PASC for another month or so just for a simple demagnetization.

I wore the watch Mon, Tue, and have it on again today and the watch has gained just 17 seconds total in that time for a daily rate of +5.6 seconds which is perfectly acceptable to me (and within spec). Since the watch is still being broken in, I hope that it will get even more accurate :-)

I have heard horror stories about PASC, but in this case they seem to have done a good job and their turnaround time was reasonable as well (especially since it was delayed because Shreve forgot to send the warranty book when they sent the watch).

HI, resurrecting an Aug 2013 thread. How did your 305 fair, did it stabilize at a reasonably accuracy over time? I just got a 305 and seems to be having similar experience you had.

I ended up selling the watch but after it came back from the service it kept good time worn in rotation with my other watches. How is your watch behaving?

I sent you a private message, but when I went to my sent folder there was none, so I'm not sure if it went through. Did it?

So here was my reply, typing it again.

I got the watch on 5 April. Wound it about 25 times and have been wearing it everyday without fail since then. In the first week it was 1-2 secs slow per day. I thought, "wow, I got an accurate watch". I thought that was it and didn't think to measure again until the end of week 3. When I did measure it I was shocked to find that instead of running slow it was 1 minute fast. If I average it out over 3 weeks, it was still very good...about 2+ secs per day. However I know it was slow the 1st week, so that meant it must have sped up a lot in weeks 2 and 3.

Curious at the sudden turn from slow to fast I monitored it more closely. When worn during the day, it runs like 12 to 15 secs fast per day. However when I laid it down to rest (measured last night with dial up) it was fast only like 2.5 secs, so thats about 6 secs over a day, which is good.

So seems like the watch runs fast when worn eh? I recall I read a similar story elsewhere. The theory behind could be that our hand movements don't tally with the oscillations of the balance wheel/hair spring so it doesn't go full amplitude before releasing the escapement, and the watch runs fast. But that's just theory, I'm sure there are many more factors involved.

If the watch can run an average of 6 secs per day, say, by running fast when worn and slowing down when at rest at night I can live with that. Otherwise I would be sending it in for regulation. Only concern being the risks associated with opening the watch up.

Your thoughts? Or input from others?

I'd wear it every day for a week and see where the watch was at the end of the seven days (as well as checking every day at the same time for daily variance). Keep in mind, the 305 is not COSC. It's accurate to Panerai's own standard which is more like +/-8 seconds a day. I think as long as it was not varying by more than 10 seconds a day I'd let it go...but maybe that's just me. As for my own 305, my pattern of wear was usually every third day so I don't think I'd have seen this issue if mine had it but there are lots of 305 owners here. Maybe start a new thread asking others if they've seen this. FWIW, I'd tend to think that an automatic that speeds up on the wrist is a rough barrel...but I am sure there are a million things it could be.
