The perfect watch differs between each individual. For myself, my perfect watch/holy grail would be a NOS Monaco 1133B. This would be THE only must have vintage watch on my list before I hit the dirt nap. Still waiting for 'the one' to show up - have been pondering the thought of asking Nic what he has at the moment in stock... Currently wearing a CAW2111 my wife bought for our anniversary (she said I'm outdated with a vintage watch... *wrong place to discuss this).
Non Heuer/non vintage watches (not worrying about a price tag); Franck Muller Cortez Chrono (white dial, blue hands) and a Patek Nautilus chronograph (blue dial). Cant help myself when it comes to beautiful square-ish chrono's...
