I'm technical, and I had a smartwatch - a Pebble, until it broke and the company shut down so I couldn't replace it.
You can replace it, from Ebay. I sold 2 of mine on there last month. rebble.io has kept the Pebbles alive. Unfortunately iOS 11 is unreliable with them but they will work with shitdroid.
The real replacement is Amazfit Bip lite. It's just like a Pebble clone but better, includes a GPS and heart monitor and costs one third of the price. I bought one direct from China for £37 and it works with the Mi Fit app. It feels like what Pebble would have become if they continued - in everything except price.
