Watch size formula

[wat44]

The formula desperately needs to include thickness. A 44mm panerai wears much bigger than a thinner 45mm watch An AP royal oak wears big on a bracelet because of the the design of the bracelet, too.

This is all very interesting but when push came to shove, I wanted a JLC Reverso on my 8"wrist.  I couldn't care less if it wasn't a perfect fit (actually, it looks good) because I wanted that icon for my own.  As many have already noted on countless threads, how many people really notice what's on your wrist?    Watch junkies yes, but the majority of people no.  As long as the lugs don't extend past your wrist, I say buy the watch you love, not the watch that merely "fits".
