Well I know this might be considered of commercial purposes but for some newbie collectors as myself, the case restoration of an octogonal defy can truly become... a Defy. Sorry, I could help it My problem is that Ialready have 2 octogonal cases ruined by watchmakers over polishing and I really would love to save them or at least send them to someone who would try to save them. I've seen that shaving metal you can re-sharpen them, but I can't find anyone who really masters that technique. Would Zenith itself do it? Any other suggestion? Thanks!
