To my mind, the 5270 feels biggest on the wrist. Then the 5370. Then the 5970. The case shape of the 5970 makes it the nicest “feel” on the wrist based on sizing for my wrist. I see 42mm as being as big as I want to go. 5270 and 5370 are at 41mm, so inside my personal limits but I feel the 5270 wears bigger than the other two.
