hey guys! Anyone out there know how to replace the crystal on a speedmaster MKII? I've heard you need a special tool to do so.
This has been covered in the forums previously. There was a great home brew method. Try the search tool.
This was that thread http://omegaforums.net/threads/mk-ii-speedy-project.16554/ You'll also need at least one o-ring for the crystal http://omegaforums.net/threads/crystal-gasket-for-speedmaster-145-014.20134/
