What was the problem with it? I was considering picking 1 up now that it's using wear os (or whatever Google is branding it now)
I expect most people will probably like the watch, so don't let my jaded opinion sway you too much.
On the hardware/physical side, I think in part was just that I haven't worn watches in so long that the thickness of it paired with the convex nature of the bottom (for the sensors to stay in contact with your skin) that I found it uncomfortable. I did order a protective case and I imagine that will add to the thickness a little too. Hopefully the stainless steel model holds up but there are reports of the non-classic aluminum model scratching fairly easily. The band also feels cheap and slippery, to the point where I am scared I will lose grip and drop the watch when I am putting it on. My wife noped out of getting one 10 seconds after trying mine due to the size, feel, and wrist location the watch needs to be positioned at for the sensors to work. I don't think the 40mm version (vs my 46mm) would have changed her mind.
Listed as 16GB of storage but less than 8GB is usable, just FYI. I do not expect to have much local media since I really won't be using the watch without my phone nearby, but for those that want to use the watch sans-phone 8GB it could be an issue.
The biggest issue for me was the software. As an example, the watch has the Play Store, one section within is titled "apps on your phone," which is apparently apps on your phone that have companion apps for the watch. One of mine is Google Clock, which I use for alarms and timers on my phone, so I install the phone app. It does not sync with the existing alarms and timers I have on the phone app - that's just basic app 101 stuff. It did install a handwashing timer app though... Just installed Google Notes which I use on my phone and it did sync my notes.
The UI also got me a couple of times setting up WiFi. I use a MAC whitelist on router, and the watch defaults to a random MAC. Change the setting, but I did not save the change because that option is off screen (I needed to scroll down more). Obviously there isn't much screen real-estate to work with, so there should be a stronger visual clue to continue scrolling (the scroll bar only shows when scrolling, it fades out otherwise, so it is easy to miss).
The watch UI does not allow you to uninstall or disable the majority of Samsung apps, but you cannot even hide them on the app screen, so I have icons for things like Bixby, Samsung Pay, 3 icons for the Samsung clock app (timer/alarm/stopwatch) if I use the Google Clock app instead, world time, Samsung text messages (I use Google messages), cluttering up the app screen. I get vendor defaults and promotion but at least allow me to hide the app icons.
Samsung health (watch app - I never installed the phone app since it needs a Samsung account or a linked Google account) wants me to track my period - even if they don't want to ask about gender at least give me the option to disable it - more app 101 stuff. The special Watch Classic watch face it came with is actually fairly nice looking, but the Text complication is also braindead - It shows a word of text on the face while also putting the first letter in calligraphy on the face. So I can have Jovec on the face with a fancy J but I cannot just have Jovec or the fancy J by itself. It seems like I am picking at nits but having to have the Jovec to get the J (you get the idea) is just bad design - allow me to choose between the J, Jovec, or J+Jovec. It is that kind of little design flaw that just annoys me to no end.
There is no easy way to switch away from Bixby to Google Assistant, although supposedly that is coming in a few months.
I cannot speak to the accuracy of the sensors, nor have I looked into how they are doing some of the tests, but it does have heartrate, blood oxygen, stress, EKG (requires Samsung Health on phone), body composition/body fat%, sleep rating (requires SS Health on phone I think), step counter, calories burned, workout time/length. It has a couple dozen workout types you can pick from but I didn't look into what makes them different (presumably the calories burned is based on heartrate + exercise type and also GPS logging on for mobile workouts and off for stationary ones)....just did the PushUps workout type and it did not attempt to calculate the number of push ups done, just heartrate and time. Maybe there is not enough wrist movement to calculate...okay, just tried the Weight Machine workout and simulated bench presses, but still only bpm and time. Rep counting would be a great addition, and would allow for things like setting rep goals with the watch counting/pushing you. Maybe the current hardware can't do that, but that should be a future design goal. Perhaps it's better linked with Samsung Health on the phone.
If there is something specific you want me to look at let me know.
