First and foremost, the Partitio is just a fantastic watch. I'm a bit of a sucker for acrylic crystals, for me they are a big part of the look and "feel" of a nice classic watch and is something I think could really suit the Partitio. Without getting into too much debate about merits of acrylic vs sapphire, does anyone have any insight into how feasible this mod might be? I did some searching and found numerous discussions about replacing other crystals with sapphire but not so much the other way around. As I understand it, this would require a crystal slightly larger than the original and then a tension ring to hold it snug in place. Is this essentially it? Would anyone happen to know a recommended size for the Partitio? I assume water resistance wouldn't be assured anymore, not that the Partitio is much of a swimming watch to begin with but hopefully it would still stand up to getting caught in the rain in short sleeves etc. Thank you for any thoughts on this!
