Jeweler. I forgot to say how to remove the case label. The usual glue for fixing case labels in times past was Rabbit skin glue because it did not darken the label paper. My tried and tested method is to use a steam lance to soften the glue, the lance is nothing more than a gallon metal container filled with water having a length of rubber hose fitted,and at the other end of the hose a short length of metal pipe partly closed at the end so I can direct the steam,the heat source is a small gas camping stove. Just keep an eye on the water level in the container!!!!! Direct the steam over the surface then pick a corner and as you peel the label keep moving the steam over the label at least two inches in front of where you are working. Above all take your time and dont steam clean your fingers.
