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.
