Post subject:  My watch looses time!

Hi,

I am a proud owner of a Panerai 305 and I am wondering how much an automatic watch, such as the 305 (or any one with the p.9000 movements) normally gain/looses time? Right know it seems to loose about 10 seconds every 24 hour.

Thanks!

I'm not sure about the accuracy of the P9000 movement in your 305, but I have been getting COSC specs on my 9001 movement, even though not COSC.

So, what are the COSC specs? How much is normal for the 9001?

Check the +- timings in the Booklet, page 12 I think. My 312 averages out if I leave it in the crown up position overnight. So mine gains in the day and looses in the night.

10 Seconds is too much ! Everything between 2 and 4 seconds is fine but I assume in your case, the watch needs a little service to be modulated.
