Epson ProSense fitness watch

As you would probably expect in this tech-obsessed world, sports watches continue to get more and more impressive with what can be monitored and displayed from your wrist during exercise. If you're willing to pay enough, you can get just about any measurable you could possibly want — speed, distance, heart-rate and all manner of advanced analytics — immediately accessible on the run.

But the one downside to sports watches has been battery life. GPS-enabled watches take a lot of power, and for athletes that means charging watches daily and perhaps not getting the full use of your watch for long-distance endurance events like century rides and Ironman triathlons.

Epson may not be familiar brand to athletes (unless you notice the name on your office equipment), but its new ProSense sports watch is in some ways a game-changer in the category — offering 46 hours of GPS tracking and heart-rate monitoring on one charge (a full 50 hours of just GPS). It has all the features you'd expect in a high-end sports watch, including a wrist-based heart-rate monitor, music storage and water-proof functionality (so you can wear in the pool and track your swimming). It's intuitive to use, and the display is easy to read during a workout. While Epson may be new to the sports-watch market, chances are it will find some quick converts.
