Tools dull, and people neglect to sharpen them. Filters clog, and people neglect to clean them. Oil needs to be changed, guitar strings lose their brightness, lightbulbs flicker and die, rooftops gather moss. We live in a world where our possessions require maintenance, and the only solution to that is to have fewer possessions. Some people choose to rent instead of buying because they don't want to deal with property upkeep (which is undoubtedly a bad deal, but one that some choose to make regardless.)
The iPhone that the author mentions gives many tools to silence notifications from apps. The real problem is the social expectation that we are always paying attention, always ready to respond. I had a phone free week last year and now frequently will leave my phone in another room on silent for hours at a time unintentionally. It irritates my friends and my wife when I don't respond to their texts immediately. And it's frustrating that these features are being foisted on us more and more. But ultimately all things require maintenance, including relationships, and ultimately we set the standard of how much we have to give and are willing to put up with.
As far as the watch goes, personally I wear a Casio Tough Solar w/ Waveceptor because in theory they should go decades without needing a battery change or needing me to set the time, unless I travel. The WVA-M640 is reasonably stylish, and G-Shocks are virtually indestructible. As long as they keep changing the rules there's no escaping daylight saving time though.
