Awsome watch with good features.
I purchased this a month ago, after my Samsung watch battery died. I spend a lot of time outdoors and thought the solor charging would be great. It is loaded with lots of features. I especially like the sleep measurement apps. Wished it was a touch screen. The app on the phone could be better.

excellent watch with a lot of features
I purchased this watch for all my adventures into the backcountry and to track of my fitness goals. sometimes it is a little confusing to use, you have to scroll through all the options the instinct has to offer. I think it would be helpful if Garmin would actually include more instruction pamplets instead of a little picture pamplet

Excellent followup
Bought this a few weeks ago after wearing the Instinct Solar 2 for 3 years. Absolutely love the upgrade. Didn't necessarily need to upgrade, but love Garmin and all the features.

Getting Accustomed
I received this as a Christmas gift and so far, I love it. I only wished that it was the smaller 45mm version, but it is starting to be less noticeable as I wear it daily. Still learning all the features, but it really a nice item. I have even stopped wearing my Tag and put it on an autowinder.

Works as expected
Mainly used for biking, running and walking. It seamlessly transmits HR to Garmin Edge, no extra HRM needed and charges in the sun while riding outside. Much more advanced fitness feature sets then the Apple Watch SE I had before. Best is it needs to be charged about 10 days vs. everyday.

Great battery, rugged, waterproof beast of a watch
I upgraded from the instinct 1 and love how this watch is still as rugged, better battery and solar charging. It’s still simple yet has all the features and widgets you need.

Nice, but..
I thought this would be a big upgrade from the solar instinct 2 50mm, but disappointingly it is not. Just a bit quicker on Garmin connect. No other big improvements. The orange ring Garmin added is kind of pointless. Should’ve saved my money and waited for another new solar instinct

Great solar watch
I have had the Instinct 3 solar (50mm) for a few weeks now and I couldn't be happier with it. I have been walking with the watch exposed on my wrist and after a few weeks of usage it still shows 94% battery life due to the solar charging. I haven't tried a lot of the other features yet, but am satisfied with the solar part.

Upgrade from Instinct 2
Had this for over a month and it has done well. I had the Instinct 2 Solar for over 3 years and this was an upgrade. I really like the larger face of the 50 and the battery life.

Amazing watch
It is indeed a wonderful convenience to no longer need to carry a charging cable for your device. The smooth operation of the watch contributes to a pleasant user experience. This freedom from constant charging anxiety allows for a more seamless integration into your daily routine. Enjoying the effortless functionality and the pleasant feel of the watch is a true benefit. It's great to have a device that offers such a worry-free aspect.

Great battery life
Only charged it once out of the box, now two months running (can't believe it holds so well).. Mainly using it for step, heart rate and exercise data.
