I agree that in this particular use case it was beneficial to wear an Apple Watch. But never ever wear a watch on your motorcycle. The force and impact can mess up your wrist in a crash. If you land on the watch it can push the case into your wrist potentially breaking it. Or hook behind something. If you do insist on a watch, wear a motorcycle jacket and long gloves over it.
Is this based on real accident statistics?
If you ride motorcycle without gloves and jacket and crash you will have much more severe injuries to care about much more certainly. So I would doubt wearing a watch is a significant risk factor.
I'd love to send you some pictures of the titanium plate in my wrist. Motorcycle accident, went over the bars in an angle that my wrists didn't like. Not caused by a watch but ever since I stopped wearing watches. Adding 100+ grams of steel near such a delicate bone is a recipe for disaster.
Also, as a developer, I don't care as much about losing functionality in my lower body. My wrists, hands and brains however are how I make my money. Even though I have full disability insurance, I still would much rather keep working than sit at home.
