In reply to Bash:
Bought a 6xPro solar titanium earlier this year (replacing an aging Suunto Ambit peak HR). Very pleased with it, used for Cycling, SUP, Kitesurfing and a bit of hiking etc etc
Was debating the 6 or 7 but didn't want or need the touch screen option on the 7 and the 6 was on offer. Plus it came with a titanium and silicone strap
Battery life is excellent, and I found it straight forward to use. It only comes off to charge, worn for work and play.
I'd suggest getting a screen protector as the bezel isn't as pronounced as the Suunto and I manged to put a couple of small scratches on it soon after purchase (I work in engineering and watches have a hard time). I made some screen protectors out of 3M Heli tape that I had to hand.
Screen isn't too bright, but there are various screens available to download, easy to configure what you want to see on the screen while doing an activity as well.
