I know this is not what you asked but if you’re mainly after performance metrics you should return your watch and get a garmin forerunner running watch. They are lighter, more reliable, and have much better battery life than android or Apple smartwatches. The analytics you can delve into on the garmin app from a run are extensive.
Are the lower-end Garmin watches the kind of thing you could wear 24/7 like a civilian? I don't see $400 but $150 could work.
I bought my original Vivoactive solely as an alternative to buying a Spintso. It quickly became my every day watch. The Vivoactive, and at least some of the others, allow you to choose different faces. I use one that looks like a black analog watch face. If you want, it has a variety of daily functions including a step counter, and a bunch of stuff I don’t use including a function that monitors sleep somehow. Ikd call it a semi-smart watch. You can receive the notifications from your phone on the watch, and read texts (if in blue tooth range), but you can’t do things like send email or texts from it. (At least the one I have.)
I've used both the RefereeWatch app and Refsix. To be totally honest, unless you really want the heat map and the move advanced stats like how much you walked and sprinted that RefSix provides, RefereeWatch is a better app. I own a Fenix 7 (watches and Macs are the only two things I really splurge on), and the only thing I really wish RefereeWatch had is the ability to use a touchscreen to start and stop the watch like RefSix has. Otherwise, I personally think RefereeWatch is better. I like the layout of RW compared to RS, and I'm fine with the general coverage map. I tried using the card and goal features in July at a pre-season tournament, and I just couldn't get comfortable with using it - particularly since I would always use paper anyway as a backup. So for me, I'll use RefereeWatch from now on and hope the developer eventually adds the feature of being able to start/stop with a touch screen instead of having to use a button.
Something I remind myself to do at the beginning of each season. With most (all?) Garmin apps I've tried, after an activity you can pull up your phone and to some limited extent edit the data collected by your watch (and sent to your phone via Bluetooth) for that activity. If you've set up the link to your account on the Garmin site, you can do things like look at your entire event history online.
I can only speak for the midrange garmins (I’ve had 235, 245) but they are great for everyday wear- sure they are not sleek but they are light and comfortable. You can go a week before charging if you don’t have gps on. very tempting but at half the weight I think the 245 is the one for me…
