I have owned my S500 B/L since the end of May when I set it to the clock on Greenwichmeantime.com.

I have been checking it now & again with my phone & it has been within a few seconds, but tonight I went back to GMT.com & checked it, I cannot believe it has only lost 2 seconds in all that time

I know the COSC certificate was showing it as very accurate, but I am astounded by this, even my Sub gains a regular 2 secs a week.

So I am a really happy chappy about this as it means I can virtually leave it & never have to adjust it.

Does anybody know if Bremont fine tune the movement or is this just how they come & I have been very lucky?
