I would have concentrated on a few Patek minute repeaters: 5078, 5074, 5016, all in platinum...presumably through auctions...plus maybe one or two independents, for instance: Dufour, Voutilainen, in other words, five watches instead of fifty. Note that they are all 'wearable', unlike PP 5002 or VC Tour de L'ile...
Yes, I know I am greedy, but as Gordon Gekko said: Greed is good :P
