How accurate is your in-house calibre?

[SmOcKxY]

Hey guys..for those of you with the inhouse P calibres..just wondering how accurate is your movement?

Today is the 1st day I've monitored my P9000 using the Greenwich Mean Time clock..after 24hrs I have gained about 3-4 secs..so I guess the test cert was right with 3.7s..anyone here is outside the -6/+8 range?

I also have a p9000, seems pretty accurate. As accurate as the handwind OP I and almost exactly the same as the Starhub box! ;p

I've been observing it for about a month, and it still stays accurate to the minute.

That's awesome!

Today is the 7th day since I synchronized the time and I gained 20secs..not too shabby for a relatively new and unproven movement..we'll see how it goes after a few months!

I have a Pam 312 since Mar and it gain less than a min each month.

my 305(P9000) gain around around 3~4sec per day
