Hi All, Here's an original Omega, super quality NATO which is leather lined. See pics - These are hard to find anymore and expensive when found. They were made in 20mm & 22mm. This is the 20mm p/n ZSZ001048 Purchased recently for my SM300 Big Triangle, but its a bit too clean for a vintage dive with heavy patina. Brand new - fitted and worn about 5mins. $220. shipped ConUS
