a6497 Accuracy

[havequick]

Hi Guys,

I'm waiting on a PAM111 and have just received a timeographer result (which weirdly wasn't provided with the origninal QC Pics, I had to request that they send Timeographer results) and whilst everything else seems acceptable, the daily rate is at +13s/day. This seems pretty bad for a brand new a6497, right?

For reference these are the results:

Rate: +13s/day
Amp: 274
Beat Error: 0.2
Lift Angle: 52 Degrees

I believe the lift angle of 52 degrees is incorrect for the 6497, but if it was done at the correct angle (I believe it's 44 degrees) would this likely result in a better daily rate or worse?


The only other rep I've had with an a6497 was a really low end IWC rep, years ago, and on the wrist this was about +1-2/s day, which kind of of blew my mind. Do you think I'm being unreasonable in requesting another watch if this one is performing at +13/s?

I know in the scheme of things +13/s isn't that bad but this is generally pretty bad for a new 6497, right?

Yes even brand new eta 6497 sometimes require a service.

I’m not a movement guy but have had 13+ watches that has run for years without problems. However if you have the opportunity to reject pls do so.

This is completely your right, of course, the more accurate the better, besides everything can be serviced and corrected, but if I understand correctly, then +13 seconds is ~ 1.5 minutes per week.
I know, everyone looks at things differently, but on the dial without minute divisions, I'm not always sure that set exactly to 1 minute, when I take the watch from the shelf in the morning, I start and set the time.

If you check this link:

You'd see that the only thing that needs improvement is the rate, and that can be adjusted. The amplitude and beat error are not adjustable and if outside the acceptable range you would have to ask for a replacement. However, lucky for you, both are in the great range. No worries.
