I heard you talking about a smartwatch and how you wanted one. I highly suggest the Pebble. Although the company is dead, the battery life of the smart watch is impeccable compared to the other crap that is out there that does too much and therefore has very little battery life. 5-7 days, actually. They are cheap right now. I highly recommend the Pebble Time Steel, which is still available on Amazon for ~$100. The Pebble Time is the next best thing at ~$50.
Until battery tech gets better, and while we are stuck with Lithium, the micro and the paper dispay on the Pebble does a great job of sipping power while still providing decent responsiveness and screen update rates.
It basically is the opposite of what other companies are trying to do, and if you do not need the fitness stuff (since Pebble never really had a stake in the health sector before the Pebble 2HR), then the notifications and apps that are available for it will be just perfect for you if all you want is to stay connected, but still not be worried about missing out.
IME, it changed my digital life basically. In some situations, I still do have some tendency to check my phone if it's out of pocket still, even though it doesn't buzz me, but only mostly for Telegram as I have long since disabled watch-buzzing for that.
EDIT: One last thing., I suggest you get a non-leather band if you want to fully explore the water-resistant properties of the wonderful pebbles!
