What is the accuracy for the high beat? My Spring is 0.5 spd. I am thinking of getting this high beat as well

I have continuously worn it for not more than 3 weeks at a time, and in that time I have not noticed any issues with accuracy. I have not checked seconds but the minutes seem to be on point. What I do see is the date does not flip exactly at midnight but around 4 minutes later. I hear that that is within spec.
