Seiko 7548 TST mod - value?

Thank you.
It does spin just stiff, it feels like it might be the gasket is slightly too thick and it’s rubbing the bezel?

It sounds as if the bezel needs a good clean.

A stiff bezel could be caused by several things. The wrong gasket. Dirt collecting under the bezel. A slightly misaligned shroud. A worn click ball. Even a combination of the above. It's a 7548 so unless modified, it will have a click ball for the bezel.
