I've got a watch with a flat mineral crystal, no cyclops, and the crystal is flawless. I was thinking that, to KEEP it that way, it might be possible to glue a flat sapphire crystal on top of it?
I don't mind if the sapphire sticks up a little, as it does on the Lunar Pilot (initially i was sort of puzzled by the LP, but have gotten used to it now).
Is there a certain type of adhesive which would be good for this? Should dry completely transparent and with no bubbles.
Just a thought experiment
