I have bought a timegrapher just to calibrate my Seiko 4R36 and 6R15 calibers.

I have noticed that my calibers have a huge variation in rates.
My Seiko Monster for example has a beat rate of -8 sec/day while dial down and +13 sec/day while on dial up.

This is a 21 seconds difference between two positions.

Is this normal? :O
