Eleven total (one 861 vintage, the rest are 2017 to present releases). Five are LEs, three are special Adam Lewis mods, a New 321 Ed White, an Apollo 8 and an original MKII which I've had from new since 1973. The easiest to wear and the one that just feels right is the New 321, the newest of the lot. I have no real interest in old 321s, birth year watches, or other esoteric details like particular dials (tropical or otherwise), bezels or bracelets. That's fine for others but not of interest to me. I buy what I like and prefer to have the full kit. I am always interested in what rabbit holes others go down to get whatever they feel will scratch their itch.
