What I wanted basic watch features (time, calendar, etc), heart rate monitor, Bluetooth connectivity (with iPhone for messages, calls, etc), activities tracking, altimeter, customizability, ruggedness (at least for swimming), size on wrist (not too bulky, not too small), weight (not too heavy), long lasting battery charge.
Fnix 5 has these features and more. 3 sizes to choose from.
Challenges (negatives ?) - Price point is a challenge, so you will have to make that leap.
Looked at Fitbit, iWatch - to small and chinsy. I'm not a huge guy, but the sizes of both of those are really for a girls wrist.
I was not certain this watch would live up to the price tag, which is steep. After wearing it for almost 2 months it certainly does. I love this watch. Running, cycling, walking, golf it nicely delivers in all areas of fitness tracking. It's easy to use and appears to be very accurate. I most like the continual heart monitoring. On the Garmin app I can review my heart rate throughout the day and especially resting heart rate at night. After an especially intense week on the bike I noted my HR was relatively high and I modified workouts and rested. Transfers seamlessly to the Garmin app and my desktop. I love the customizable watch faces. Fun!
Highly recommend. And I have been a long time customer of Bike Tires D. and they are the best. Nothing but good experiences with them.
