So the GBD-H2000 isn't a SmartWatch like a Apple or Galaxy watch.
But if like me you want a fitness tracker that has that rugged G-Shock look, then look no further.
I had the GSW-H1000 and loved, apart from it's woeful battery life, well the GBD-H1000 took all the features and functionality of the it's predecessors, improved on it, and improved the battery life out of sight.
Definitely worth upgrading.
The only negative I will say is that if like me you are getting a little older and you ability to read fine print is waning, you may struggle to read some of the graphics on this watch.
