I have a Fossil Q Hybrid. I would say buy it, but make sure you can return it after opening the box.

Their bluetooth stack seems rock solid. Especially coming from Garmin where intermittent issues were the norm for me.

I'm only interested in 4 things: counting steps, getting calendar notifications, getting call notifications and getting text notifications.

Steps counting and syncing works without issues, calendar events work without issues. Text and call notifications stopped working for me altogether.

Basically, it either works really well or not at all.

I'd be willing to invest time into this to get it to work, but their support is not much help. It doesn't go beyond checklist and "have you tried re-pairing and enabling all permissions".

It's a shame they sold to Google. They seem to have had some really good talent there and I fear it is going to be wasted at Google.

I like my Fossil Q Explorist well enough. I have the Gen 3 which doesn't have the heart rate monitor or GPS, but on the whole it's a good watch. If you want a smart watch that can do all the smart stuff and last a couple days, I'd look elsewhere. Fossil watches don't have the best battery life. The Gen 4 says like 2 days on standby a day with usage. I get about 6-8 hours tops actually using the watch (looking at notifications quickly and swiping them away, looking at the time, changing songs on my phone), and the charge time is like 3 hours. They suggest it can do sleep tracking, but I've never tested it because I need to charge it every night.

If you don't mind having a watch that is mostly for doing watch things, and then charging it every night - Fossil is nice. But I would look elsewhere if you want a smart watch for daily use doing "smart" things.
