Hi all, hey does anyone know where I can get the round caseback O ring for a Relic watch model ZR55047? It's that cool color changing model and I just replaced the batteries but noticed the O ring is kinda dry and cracked. It's still all there but I'd feel better replacing it. Any help appreciated. I'll post pics of the watch if someone wants. Any info on the watch itself appreciated too, when they made them and so on.
