Is it better to leave the original one on or will it hurt the value if it gets changed? Mine has a few tiny scratches. Nothing crazy but was just wondering.
No need to replace the hesalite. Go get yourselves a tube of poly watch. It’ll take out the scratches in no time
As has been said, this will work fine: And not surprisingly, you'll even find threads on this topic here... https://omegaforums.net/threads/before-after-scratch-photos-on-my-speedy.19657/
Polish or replace with authentic Omega crystal at a greater expense. Totally your preference, and the value of the watch is not affected. Just don't replace with a non-Omega generic crystal.
Novus plastic polishes also do a good job at perhaps a lower cost than Polywatch. I use rifle patches as the cloth because they're easier to handle and you can just throw them away when you're done. 2-1/2" square ones. Tom
I used meguiars plastix with microfiber towels and it worked great. Some deeper scratches still remain but it's much better than before.
