I went for an 1803 with gold dial, no diamonds. It's the classic look and may well be the easiest to sell on. The 18038 from 1978 onwards benefits from a quickset date.
The Oysterquartz has the benefit of not having to change the day/date when not worn regularly. But having seen an Oysterquartz in the flesh, the quartz tick put me off as it looked incongruous in a vintage watch.
The bark models are an acquired taste, although I do admire them.
