For some reason, I have what seems to be an unused plexi for a 146.012 Chronostop, part# 063PZ5223, silver tension ring. Absolutely no clue where it comes from as I’ve never owned the watch but I figured somebody here might have use for it. Here are a few pictures, not the best but when a not-so-great photographer takes pictures of a see-through object in bad light… well. I’m in Germany, happy to ship wherever. Get in touch and we’ll figure something out. Thanks OF for the space!
