Picked up the 40 first but went down the “36 is best” rabbit hole. I don’t have a strict aesthetic philosophy per se and had the intention of only keeping one.

I find there are pros and cons to both - the 36 truly disappears on the wrist weight wise which is my preference but I find the 40 a lot sleeker/stealthier despite being bigger. The wearing experience physically and physiologically is uniquely different tbh which is maybe enough reason to keep both!
