While the movement is in the cleaning machine, we can get on with the rebuilding of the crown for water resistance.

The old gasket is removed

We install a new custom made gasket for the crown.

The movement is now finished in the cleaning machine and ready to assemble and lubricate.

Beautiful new crystal? I think I'll send my exact one in too for evaluation....but angling for a new crystal as well. Seiko US who inspected mine says crystal discontinued....I think I can still find one. Maybe the "Seikologist" is up for the task. Check back and see....
