Since the Seiko low end movements (like the 7s26) perform very differently depending on the position and on the state of wind ( mine skx013 was +20sec dial up, -20 dial down), they sometimes are very difficult to regulate perfectly even with the right equipment.. I regulated mine muself, with tools bought from Amazon, and i did not scrathed the watch 
. Anyway at (+7 , +12, +2) it is way less regular and precise compared to my ETA Fortis, which is constant at -4s/d regardless of the position. I guess with higher end Seiko movements, starting with 6r15, the story will be different.
