I have been using the Garmin watches after I used the Apple Watch but detested having to charge the watch almost everyday. I started with the Forerunner 255 (7 day battery life, then upgraded to the Fenix 8 solar with battery life of 18 days. I can certainly entertain getting a Pebble watch since I loved the timer feature that calculated the time the timer would go off so you did not have to do the math in your head. I have yet to see another watch do this even though I have asked many times :). Here are some must haves….bigger display with minimal borders, thinner than leading watches and 30 day battery life. Godspeed.
