A quick response, unfortunately the CD 'sharpie' marker are temporary at best.
I am hoping for an air brush system for Christmas (or I will just buy one). I saw a posting about building up the finish with an air brush. See the link Ranier posted as he beat me to this!
Again this should last longer then the airbrush but it has not got the durability of a paint that was baked on as the original is.
Sorry, no help here but if you have an air brush that might work better.
I have done eleven restorations to date for people on the HP-01 and even made my own crystals from armoured plexi glass. These do not have the Hewlett Packard label/name on them. I prefer the armored plexiglass as it can be polished at any time to remove scratches. The mineral glass can be polished with water and diamond paste only when removed from the watch, even then it is a long involved process.
If your crystal does not have any major chips from the corner (pictures?) then after removing the movement the crystal can be removed and flipped over.
I will email you later and DO NOT start a dis-assembly UNLESS you know what you are doing!!!! Removing the battery holder can destroy the PCB if allowed to rotate.
