I switched to a Suunto solar harvesting watch after my last watch wouldn't last past 10 hours. Their claim of ~60 hours activity time seems pretty close based on the shorter 6-10 hour runs and bikes I've done with it so far. Definitely doesn't have the ecosystem that Garmin does but it checked the 3 boxes I cared about: gps accuracy, battery life, and price (got in on sale for about 1/2 the price of a forerunner)
Suunto Vertical (I have the solar one) best gps settings = 60hr battery
Agree! I had used Suunto 9 for years and years and only switched to Suunto Vertical with solar panel recently, got it on Black Friday discount £200 off ❤️
I’m a big fan of my Suunto Verttical solar. Insane battery life and all the bells and whistles for my needs.
I initially went from a Series 8 to an AW Ultra and ultimately decided that I wanted to try something that was more of a dedicated sports watch, so I eventually got the Suunto Vertical Titanium Solar. In some ways it’s been a step backwards (it feels “old” compared to an Apple Watch, particularly the MIP screen and general pared-back functionality) but it’s also great for what I need. I mostly trail run, hike and gravel bike with it, so the mapping functionality is helpful. It’s super easy to create a route on the Suunto app (or Strava) and then immediately sync it to the watch. This is something that never really worked on Apple Watches, I know you can use 3rd party apps but it was just not easy or seamless enough for me. I also appreciate the ruggedness of the Suunto, I bang it around all the time and it still looks great, the buttons are nice and I like that it doesn’t look like an Apple Watch. The HR monitor kinda sucks if you are super granular about that data. It syncs to Apple Health but not as seamlessly as AW (some data doesn’t sync fully, like sleep stages). I think the data displays in the Suunto app could be refreshed too, it was a lot easier to digest data in the Apple Health app. Overall I think the Suunto hardware is great, but the software is just OK.
almost my case. I still have garmin fr945, suunto 9 and vertical 1. both suunto have big troubles with hr measurement, sleep accuracy not good. for cycling I have wahoo bolt v2 and v3, for concept2 - only ErgData app. withings smart scales is more than enough for me. one thing for me what suunto is missing is “resume later” function, especially for walking or hiking. I like suunto maps and navigation. now I’m confused to choose vertical 2 or race 2. both have better (I hope so) hr measurement and… thats all. ok ok, vertical 2 have led flashlight. vertical 2 disappointed me without local music storage and without nfc. but I like suunto for menu design, because garmin UI looks like designed for childs - not solid.
