Precisionist 96B153 Accuracy Tracking

[v76]

+2s/y would be phenomenal, even for a HAQ watch!

My EZchrono is under 2 s/y at the last measurement.

Still looking good:



Funny thing is, the more accurate the tracking, the more I want to wear it ...

I think I read that the watch uses a lithium 2016 battery and because of the sweeping second hand battery life is over a year.

For me this is not a problem since I have the watch tools and knowledge to open the back and change batteries.

After 16 weeks it's still running less than 0.5 seconds fast:



This week I found that I could observe the daily drift of my RC wall clock over the course of a day when comparing it to my Precisionist.

This is definitely the most accurate watch I have ever owned.

9 weeks on, and my Precisionist is less than 0.2 seconds fast. At this rate, about 1s/yr gain

Looks like the B1s are performing well, gaijin ...

Thanks for the update - that's good to hear!

Week 17 and it is now trending at <+1s/y:

Week 12, and it's now +0.1s - trending less than +1s/y as well!

Still chugging along at a linear trend predicting <+1s/y:



I forgot to mention last week that I did NOT adjust for DST, so I have to imagine myself one hour ahead while wearing it.
