Horological Meandering

Seiko's adjustment specifications for the 4R36 ...

 

... at least, as far as I could retrieve them, is +- 20 sec./day in the dial up position, and +- 30 sec/day in 6 up and 9 up, which is rather generous, I agree. However, as my own test showed, the movement is still within the chronometer specifications, even without any manual regulation. Conversations with other Seiko 5 wearer appear to confirm that experience.
