IMO, no, the Apple watch is a distraction in many ways. Another thing to charge. Battery anxiety. Pestering you with information you never needed before and don't need now. Another way to spend money...bands, accessories, etc.
Apple Watch contributes to lower sense of wellbeing. There are so many ways that it's just wrong that I can't but scratch the surface with my little list.
i think the opinion you are expressing is actually one held by a great number of people.
for people who do enjoy the Watch, notifications on your wrist is usually listed as a primary factor for their liking the Watch.
i think setting the notifications to a degree that is comfortable and useful and manageable is probably different for each person.
for me, getting control of what and how often notifications pop up made me more productive and aware of my activities and surroundings. all in a very unobtrusive way, without need to pick up and interact with my iPhone.
but i do agree with you that for many, learning how to set the watch to a level that is useful and not distracting, seems to be difficult for many people.
there was a learning curve for me to remember what is set by the iPhone's general Settings, what is set on the Watch app on the iPhone, and what is set directly on the Watch itself, and how to resolve setting conflicts.
i can honestly say it is my most favourite piece of tech. and, the only tech that i have that i will definitely update every year or so.
payments, transit, workouts, messages, hours spent in sunlight, time spent in REM sleep. calories used during active hours, unlocking my mac, etc etc. all just there. thanks to apple's iCloud understanding what device you currently are using or have with you, and through Continuity and Handoff.
