Long battery; but wrist HR tracking is inconsistent.

They do, Garmin also makes fashion smartwatches. I have a Lily 2 Classic which I love
TL;DR Yes, overall, this IS a good switch from the Apple Watch if you're prioritizing battery life, fitness tracking, and a cute, dainty look. When my SO and I started a weight loss journey early this year, I encouraged her to get a Lily 2 -the Classic, because she's frugal and was unsure if she'd like it or use it. Recently, she said to me, "This is something that I never thought I needed, that I now can't imagine not having." She jokingly calls herself "Princess Luddite" (she's not, really). She's an executive, and the size & style of the Lily was a huge plus, as well as the reasonable cost. She loves that most people simply see it as a watch, not a fitness or smart watch. Battery life IS terrific on Garmins. GPS use will run down the battery, but my Venu is still a multi-day smart watch unless I'm using the GPS all day long, like skiing or sailboat racing. The Classic is missing the onboard GPS, which the Sport has. That should do the trick nicely for tracking your outdoor runs, as it does on my Venu 3 for my cycling, skiing, and more -no need for your phone to be with you. Specs say that it does control smartphone music, but neither of us does that. We use Tidal, which is not compatible. Spotify is compatible, IDK about Apple Music. She isn't much of a fitness person. However, as a walker, she particularly enjoys the step tracking and sleep tracking features. Lily tracks her sleep better than my Venu, which seems iffy on my falling asleep (could be me!). Sleep tracking might be the weakest feature on Garmins in general. Notifications/message reading work well with all of my messaging apps (I'm not sure about Viber, but it should work the same), and are customizable as you desire, so you're not overwhelmed with unimportant ones. Bands are easy to change; she wears a more posh, dressy, jewelry-like, less sporty-looking band. I change my bands and watch faces for everyday casual wear vs more formal events. She hasn't mentioned any durability concerns or wear in 2 years of daily use, even from gardening. She's mainly in an office, so not really beating it up. The Sport has nearly all the activity tracking features available on my old Fenix 5, as well as on my Venu 3. It's not missing much, TBH. Apple compatibility appears comparable. As Android users, we just have access to messaging response options that Apple does not allow, but all the notifications should be the same on an iPhone. She doesn't use any third-party apps, but they should work, I guess?
My wife has the Lily 2 (non GPS version). I bought it so she can check her SP0² - which has now vanished from the watch I get the appeal, but as a fitness watch, it just doesn't do anything very well
The Lily 2 is a great, low-cost, low profile option. It doesn’t even look like a sports watch. My sister says it looks like a Movado, but half the price. It does everything she needs, with additional features and details accessible on the app.
Surprised no one said lily 2. I have it and its very feminine
I went this route. They have different watches with different styles and for different needs. I use the Lily 2 because I have a tiny wrist. I love it.
