This watch is my daily watch. At the office it looks sophisticated with one watch face and then I can easily switch faces for the weekend. Battery life is pretty good. I get 3-4 days between charge while using it as a smart watch each day and running/cycling in the morning or evening. Quite accurate for pool swimming as well.

I love this watch! From its functionality and measuring capabilities to its sleek design and eye-catching comments, this has been a great watch. That Garmin 645 has taken me through the training and completion of 3 international marathons - Rome, Mont Saint Michel, and Athens. I usually charge twice per week. The battery has never died on me. Highly recommend.

I had the 235 before this which served me just fine. The 645 was a nice upgrade. I feel as though the battery life is what to be expected with the music feature, and when not using the music it lasts me at least all week. The GPS connects super fast almost anywhere I am, which is something that was really taking awhile with my old 235. The only complaint I have is it sometimes struggles with bluetooth connectivity, both to my phone and the headphones I have paired with it. This isn't really enough of an issue to cause major problems, just slightly annoying when I'm trying to go run and it won't connect to my headphones. Still recommend it though.

This watch has been an extremely durable and well designed watch. I have had this watch since 16/10/2019 and it has not let me down yet. It has an extremely good battery life and is very easy to use. My only complaint about this watch is that for an Apple user (iPhone and MacBook Pro) it's very difficult to download music into my watch. I don't know if it is just user error or something else but that is why it's a 4/5 stars. Other than that, this watch is one of my favourites.

Its set up for running, so it does that perfectly, but it also is great for swimming since its so thin.

Much more accurate than an apple watch just a tad less functional
