920XT / Fenix / Ambit.
Depends what you are looking for.

I've switched to a traditional GPS for navigation and a vivofit band for heart rate and time.

Fenix 5/6, but really depends on your budget. They also have solar versions where battery life may be even less of an issue 😉

Got something to say?
