I think I've found my One Watch. I have no desire to wear any of my others anymore (not that I really have an extensive collection), and can't really think of finding another one in the future to supplant it.
Thanks for the input. I am pretty sure I saw a Caccioppoli book at my last NSM visit.
As for a bespoke cotton suit, I haven't found anything that fits off the rack, I'm BSAS (broad-shouldered and short.) And I like the worn-in look a cotton suit gets over time. This wouldn't be for business, or daily wear.
