Hi, I've read that these movements the hands aren't interchangeable. But what about the day/date wheel? Are these interchangeable for all movements or not?
Like 7548 to 7549 or 6309? I'm talking only the day/date wheels.
I've search around but no answers.


Thanks, Dave.

Have a look on Borels Dave, the date wheel seems to be the same in them all so i would assume the day is as well (i could be wrong though :) )

Hi Dave,
Because the hand hole sizes are larger on the 7549, the day disc also has a larger hole in the center to accommodate the larger hour wheel pipe. Therefore it is a different day disc and incompatible with the 7548 or 6309. The date disc is the same, however between all three that you mentioned. Above information gleaned from Seiko parts guides.
