I've been hunting around and can't seem to find any definitive source for the Poljot 3133 technical specifications. For example, I've seen the daily rate quoted as -10/+20s and also as -10/+40s or even -20/+40s. It's possible that more than one of these is correct. There should a maximum daily variance and a mean daily variance, which is probably changes depending on whether or not the chronograph is engaged. Any idea where I can find all these figures?
