Response to Buffing your crystals
I've used ordinary toothpaste and gotten satisfactory results. Toothpaste contains a very fine abrasive (hydrated silica which is basically microscopic GLASS particles) that will smoothly polish any plastic surface.
I'd put a dab on a folded paper towel, put a few drops of water on it, and then press the outside surface of the removed crystal against the toothpaste (the paper towel is resting on top of a firm surface like a bathroom sink counter), and then slowly began pushing the crystal around in circles with my thumb.
After a few minutes the crystal is washed off and will no longer have any fine scratches on it. This method is not, however, that effective in removing "deep" scratches, but will soften their appearance.
I would caution anybody who is using power tools to remove deep scratches from plastic crystals to remember that to remove such a scratch also requires that ALOT of surrounding plastic be removed with it. This will significantly reduce the thickness of the crystal over a large area and make it LESS shatter resistant.
I've learned to "live" with a few scratches on my timepieces. It is part of the "charm" of owning and wearing any watch. They show that the item has been in use for many years and is valued enough to keep wearing.
Don't think of them as scratches, but, rather, as the "patina" that a valued timepiece EARNS over time...sort of like the wrinkles on an aging guy's still handsome face (which younger women often find very attractive...LOL!).
