It doesn't have anything to do with that. I've been wearing mechanical watches for as long as I can remember but they are only used to tell the time which isn't very often. A smart watch however is used for various types of functionality and far more often so wearing long sleeves especially a a coat with tight fitting sleeves like my North Face rain coat makes using it very difficult. This morning rather then using my watch to pay with ApplePay in the coffee shop I had to take my phone out of my pocket. Today was the first time I couldn't use ApplePay on my watch.
