Epix pro gen 2 51mm and instinct 3 solar 50mm. One AMOLED and one SOLAR I like both screens.

If you’re looking for something super practical and easy to read, I’d recommend the Garmin Instinct 3 Solar 50mm. The numbers are extremely visible in pretty much any lighting condition, which makes it great for outdoor use. On top of that, you barely need to charge it — battery life is honestly one of its biggest strengths. If you want something similar but much more advanced, then the Garmin Enduro 3 would be the next level option. Same great visibility and insane battery life, but with more features and performance-focused tools.

I’m officially on day 51 since original charge. I have 68% (24 days) battery remaining. I do 3x 30 min runs using standard GPS per week. Notifications turned off and pulse ox set to on demand. I came from a Forerunner 255 which is a great watch too. But I’m really enjoying the solar side of the i3 50mm

The 50mm version is amazing, with a ton of battery life and enough smart features. Although you can get the 2X probably for cheaper somehere, which is almost identical. But it all comes down to whether you are willing to pay 315. I think it's worth it, especially for a first personal Garmin watch.

OP should try a Garmin Instinct 3 50mm solar! With the right settings and enough sunlight on the daily, you could theoretically never need to charge it again. As someone that uses it for daily bike commutes, I get at least 3 weeks on one charge with it.

Fax. I came from an instinct 3 50mm solar and knowing what I know now, I wish I would’ve saved for the enduro 3.
