I hate to call something a 10/10 so I wont but this is very close.  A rarity these days.  A super condition Matte dial 16660  with great patina Mark 1  tritium dial and hands in mint condition. The case is super thick and sharp and appears to have been only lightly polished with the original bevels still apparent.  The bracelet is original and have 12 full links plus diver extension.  Movement running as it should.  Accompanied with box, papers, wallet, calendar and polishing cloth - a nice set to have these days
