I am having trouble finding tropics/crystals for my PAMs. One is a 212 with a 44mm crystal and the other is a 217 with a 47mm crystal. I remember a few years ago, we had a bunch of these with crystals that had been fractured.....I have had them replaced before and unfortunately, I need them replaced again. If ANYONE knows where I can get them, please let me know. Any info will be greatly appreciated.!!
