The Fenix 3 is still going strong for me after two years with it. I don't usually use GPS on it, so I charge it about once a week when it's around 50% charge (sometimes I forget to check, which is why I plan for about weekly charging).

Also, the edge is slightly raised above the face on it, so while there are a couple of nicks on the bezel, there are no scratches on the glass. The sapphire glass may also be part of that.

App ecosystem is minimal, but I honestly don't need any apps anyway.

I got mine for running/swimming/activities but I actually really like it as a daily smartwatch. Like you said, some nicks on the bezel but otherwise it seems indestructible.

Pebble was my watch for years until Garmin released the vivoactive HR. While Garmin loses style points compared to Pebble, it has much better features and durability.

The first weekend I had it, I tested it by wearing it on a Tough Mudder...it survived without a scratch. 2 years later and the Garmin battery life is still over a week. If you miss Pebble and want something still being updated, look at the Garmin watches (but I wouldn't go any lower than the current vivoactive3 line)

I have a refurbished 235. I use it mainly for running, it lasts forever, it's light and you can see your activity history on it - unlike the fitbit i previously had.

Seconded. I really like mine. It does all I need from a watch and then some.

I also got mine replaced without any hassle after it failed.
