Although Apple seems to be moving their focus for marketing the Watch towards health conscious consumers, there's a significant number of people who find wearing the device at work absolutely necessary to stay in touch. Many service industry workers are prohibited from checking phones during the workday or while on shift, but checking a watch is acceptable, allowing them to break the monotony of a quiet afternoon without breaking company policies or seeming inattentive to customers – a scenario I hadn't previously considered (we didn't even have smartphones when I was working on a shop floor, and i'm not that old!).
