Hello all. Was unnable to find any info on this particular model so i decided to make an account in here to see if anyone could help me out. Its a Zeno Watch ZN-001 in 31.5mm with the Miyota movement just like its 36mm brother. This one was purchased a long time ago in Japan. The edges of the crystal have many small cracks, so i was looking to replace it, but i'm unnable to find a replacement. My local watchmaker did not have any compatible crystals. I contacted ZENO North America, and they were unnable to help because this watch was only created for the Japanese market (possibly Hong Kong as well). My calipers aren't that great, but the crystal size is domed acrylic in 26.8 or 26.9mm.
