Overview
A road run, a gym floor or a tennis court is where this watch is meant to be worn, with GPS for outdoor routes and indoor apps for the rest. It has a round case, a silicone band and a deployant clasp.
Runners get the core of a training watch: GPS tracking, optical heart rate and a bright AMOLED screen, with many indoor apps for gym days. The sports list and the water field disagree, which calls for a question to the seller.
Who it's for
Road runners, gym users and hikers who track sessions on the wrist will use the profiles. Anyone planning to swim should hold off, since the water field says the watch is not water resistant.
Pros and cons
- AMOLED screen with touch
- Optical heart rate sensor
- Many sports profiles
- Works with iPhone and Android
- Water resistance conflicts with swimming
- Package contents are vaguely described
- Case is resin, not metal
Performance notes
GPS fixes position for outdoor runs, while the optical sensor reads heart rate at the wrist and the skin response sensor adds stress data. Buttons give dependable control while moving, with the touchscreen as an extra. Battery life depends on how long GPS stays on.
