I am also fortunate to enjoy both the 390 and the 372.
I also had the same fears that it would wear too big...even though i wear a 339 and 249 at times
They are wonderful compliment to each other.
It wears beautifully, has a unlimited range of straps that look terrific holding it on your wrist and the aesthetics of the watch are truly engaging!
