Great watch if you like gadgets and want to keep track of your activities. I bike, walk and play golf. This is the only watch I need. This watch does not have to be connected to your phone to operate. All build in sensors work great. Garmin is good at updating their products when necessary. It looks rugged and is not the watch that most others are wearing.
Bottom line this is a great watch and not a toy or fashion statement.
I normally don't wear a watch except for dress occasions however the features on this watch were intriguing - have the ability to follow trails while hiking, as well as navigate and see topo lines along with the smart phone features AND the cycling sensor capability for training were enough to convert me to a daily and now nightly watch wearer. Yes, I wear it to bed to track sleep quality which is a big factor in training load adaptation recovery. Very happy with this. The battery lasts well over week easily the way I normally use it, screen is easy to see in daylight even for my aging eyes, and I've gotten use to it's size now (it is very big). It's hard to say you could recommend a watch this expensive to someone as it's expensive for a watch however when comparing to the price of others in it's class and the features I would say if you are in the market for this kind of watch and can afford it, it's the cat's meow - Get it, you won't be disappointed.
The watch would be a game changer if it had built-in World clock (Third party watch faces offer limited World Time Zones). The battery life is very good. The terminal for USB connection does not have cover. However, I believe the contact pins are gold-plated for anti-corrosion due to salty sweat and I hope they will last.

Coparison - Garmin 810.
Watch Custom faces make it great. It does ALL sports....xc skiing - covered. Bike inside...covered. Amazing.
The Garmin site is great.
GPS maps ON THE WATCH cover being off the grid.
It is good to 100m, so I am not worried about swimming with it (there is a 3rd party dive computer app....).
Basically, the BEST sports watch on the market by far. I have it at 10% screen on all the time, second hand running all the time...with a custom face that a programmer made to my specs for a few dollars (beer money)...GMT4 btw, great programmer...he added the second hand as a request (to be fair, many of us wanted that).
I spoke to Garmin support to ask for a feature. They picked up, were respectful and responsive and later (the next release) my request was a reality. No one beats that in the whole market. I am amazed by that ....it was probably a common request but still, nice support is so rare these days.
Only con a bit pricey.
