I absolutely love my Polerouter 204612/2 It does have a unsigned crystal(although with a correct "trapezoid" lens), possibly aftermarket one. The biggest issue was that it was cracked at 11'o and 5'o clock. I knew eventually, I would have to replace the crystal with an new one so as to not have moisture ingress through the cracks or have it disintegrate on me entirely. I did stay on the lookout for a signed UG Polerouter plexi but I knew those were rare as hens teeth or almost unicorn like. Untill, I found one. As an added bonus I found a proper buckle and a UG strap for it. I guess sometimes you get lucky. Now sending the watch to my watchmaker for a spa treatment and plexi exchange. Just wanted to share my excitement, I genuinely thought I'd never find one these. Stay safe and healthy. All the best to everyone.
