Garmin
Forerunner 255 Series
Long battery; but wrist HR tracking is inconsistent.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I have a Forerunner 245 with Music. It does the job. I have it in aqua blue. It also doesn't cost a gazillion pounds to buy.
I use a Forerunner 245 Music. Relatively cheap, does the job along with a chest strap HRM.
I have a venu 3 and love it! Had the forerunner 245 music for several years prior to making the switch to my venu 3 this year. I workout everyday and it has tons of tracking options as well as being touch screen and having all the smart watch capabilities.
I also have the 245 Music, but the battery life is decreasing and am looking to upgrade. Not sure what I should go for. I love the Fenix design and functionality, but it’s a bit pricey. I mainly run, bike and walk/hike. Any feedback is welcome :)
Been very happy with my Forerunner 245 Music - though I rarely play music through the watch since I carry my iPhone for live tracking anyway. It’s only a few dollars more or less, but if you’re gonna carry another device, you could do without the music part of a 255 forerunner
I recently upgraded from the Forerunner 245 Music to the 265 after I broke the strap bracket thingamajig while wrestling with my son. It's taken some time to organize various screens how I like them, but I've really liked the upgrade. The watch has new virtual Garmin coach plans, which I'm using for a 5K race in March. I like that it's mixing in some non-running workouts, which I've always been concerned would interfere with my running. But since "coach" suggests them as part of the plan, I'm ok with it. The 965 has some extra features that were appealing, but I felt like it wasn't worth the additional cost and it was a little big for my wrist.
I switched 6 years ago, and since then I’ve used the Garmin Forerunner 245 Music, Fenix 6X, and most recently, the Fenix 8. Garmin is really good at heart rate measurements, and its GPS accuracy is excellent — you never have any issues with it. And battery life was also the main reason I switched from the Apple Watch. The Apple Watch is fine for walking, but for other workouts and sports, you’ll have to switch it. I’m sure you’ll be happy once you switch to Garmin. Kind regards,
