Buy one or two at afforable prices with no waiting that you think you will like and hold them for 6 months.
Take note of what you like and what you don't -- because you will find things you can't figure out in advance without wearing / owning it.
For example:
Pro: beautiful dial, nice heft of white gold, interesting complication
Con: nobody ever heard of it, the collaboration died, crown too small, hard to wind, short running time
Pro: useful triple date complication (theoretically), bright color salmon dial
Con: hard to read the date, impossible to see the chrono sub-dial hands, no lume, thick and heavy, hard to wind due to crown protectors
Pro: interesting complication, titanium case, wild straps and bracelet included, famous designer, makes me laugh to look at it
Con: impossible to wind without tool, can't use tool to set it and setting is a pain in the fingers, went out of business, spare parts expensive and hard to find
Pro: funky design, some nice touches, reasonable price
Con: looks unfinished because there is no second hand and no cover - the bare arbor is visible when you look at the watch, annoying marketing strategy
Pro: German craftsmanship, small, nice guy, unusual complication
Con: quickly became boring in every respect
Pro: novel ideas, fascination implementation, lots of info
Con: ultimately a pain in the arse to set and read it
Pro: Nice theme aviation watch
Con: impossible to see hour and minute hands from many angles
Pros: useful travel watches, funky design, famous designer, amusing touches
Con: went out of business (at least 2 or 3 times), parts hard to find, almost impossible to wind and set due to case/crown situations
Pros: Many vitutues, no need to explain to anyone
Cons: At the time worth more than any of my cars, a bit flashy for my lifestyle, felt vunerable wearing it
Pros: Great watchmaker, interesting complications both front and rear, beautiful hands and numerals, dial design very nice
Cons: Small crown hard to wind, retro hand a bit undependable, too small on my wrist, gold too much for regular wearing
Pros: everything about it
Cons: nearly nothing; a bit too precious for frequent wearing
And so be prepared to fall in and out of love a few times on your way to collecting a few KEEPERS.
