I was under the impression that the 007 dial was textured... Not sure why I thought that.
Completely feasible project.
XDING- the tube, crown, crystal and valve you can do yourself. If you've got more balls you can do the dial swap, but it requires removing the hands.
Here's my franken 45.5mm UPO with Gen Tube, GEN Crown, and GEN Crystal
Next mods will be dial and bracelet if I can afford one!
