Filling in the lettering with enamel paint is REALLY easy, and wiping off the excess is only slightly harder to do. ;-)However, you can take any white bezel 6900 and fill in the lettering with black enamel. It's really not hard to do.
Sjors is right -- it really IS quite easy -- you just wipe the flat upper part of the bezel (where the excess paint is) without pressing so hard that you wipe the paint out of the grooves/recesses/engraved letters.The letters are recessed in the bezel. You only wipe the paint above the letters. It's realy quite easy
