I realize comfort is a personal thing, so this may be a useless post (but no more useless than most, I suspect).
In the past, I've tried on several versions of Speedy (moonwatch, FOIS, speedy racing) and found them all to be really comfortable, and they all seemed to wear thinner than the measurements.
I've also recently tried on a number of other chronos that I like (new Hamilton intramatic 68, new IWC spitfire chrono, Breguet Type XXI) and found them all to be way to thick, or clunky or just uncomfortable, even for only a few minutes in the AD.
Is my only hope to buy a version of speedy, or are there other chronos out there that can match it in terms of comfort?
Side note - I find Daytonas to be super comfy also but realize it's currently not in the cards in terms of finding one.
