The 30mm handwound Omegas were freaks of horology. Either they have all been superbly maintained or else they were made with materials and design that simply seems to resist wearing. My watchmaker tells me he's never seen onw with any wear. There were a handful of Omega 30mm calibers made from about the 1940s to about the early 1960s. Here's a reasonably complete list: 13 Ligne (=30mm) movements: New numbers: 260 261 262 265 266 267 268 280 281 283 284 285 Old caliber numbers: 28 28SC 28.9 30 30.10RA 30T2 30SCt2 30T1 30T2RG 30T3 This watch is the zenith of 30mm Omegasand something of a Holy Grail to collectors.
