Thanks

I need to look more into that. With the crown on the watch its a bit hard to measure. But I did measure the one I removed, a category B2 crown, and it was 3,8mm. When comparing that crown to the one one my watch they seam to be exactly the same height. Maybe I should have it removed to check that its not a crown for a Seamaster 300. Anyone who knows the thickness of that?
edit: corrected spelling.
