Long battery, but wrist HR often inaccurate.

I've given up on the Strava Wear OS app as it constantly stops recording for me when running, cycling or on elliptical ... Have tried on Ticwatch 3 & 5 and now the OnePlus Watch 3. I now use the manufacturer health app on the watch (Ohealth for OnePlus) and have the sync to Strava on ... Works flawlessly. No maps though!
As someone who has used a good amount of the alternatives, I fall under the case of nothing really beats a Pebble. Wear OS is still an unstable mess imo and feels too much like just a phone on my wrist. The Pebble actually feels like an extension of my phones abilities but not overwhelmingly so. Plus, you can make your own apps for it if you are into it. The BangleJS2 and Bip are some alternatives but I didn't enjoy them anywhere near as much. A readable screen, you are looking at e-ink or the e paper we get on the Pebble, Bangle, Bip, JS, Fossil HR (I believe that is what they called their hybrid) and I believe some Garmin watches, though they fall into the category of I haven't used them. The battery life is the killer feature on the Pebble to me. Though the Bangle and Bip have great battery, the pebble just did more with it to me. The ability to reply is nice but a touch screen only was a deal-breaker for most watches nowadays. The buttons are really nice when I need them like when wearing gloves for work. I'm excited for my Time 2, and have my Time Steel on while I wait. I took off my Ticwatch Pro 3 and it has sat with getting put on the charger once a month to keep the battery from just stopping from working. If you have concern, grab a used time for cheap if you can and use it for a bit. Don't like it? Cancel your preorder and you can find something you do.
