Epson Runsense SF-510
When most people think of Epson, they think of printers. But Epson has actually been producing watches right from their start in the late 1960s. In 2014, they upped their game to fitness trackers. Now, several years later, Epson boasts an entire line of activity monitors and GPS watches.
The Epson Runsense SF-510 is fourth in this line of GPS watches, which ranges from 110 to 810. As you probably guessed, the SF-510 has more features than the 110 or 310 that came before it, but fewer than the 710 or 810 following it. As you also probably figured, it is more expensive than the first two models and less expensive than the latter two — and excellent middle-ground GPS watch that appeals to a broad spectrum of exercisers.

The customization of the SF-510 is not the only advanced featured in this GPS watch. In addition to its GPS tracking capabilities, it utilizes a Smart Stride Sensor which is able to to continue tracking your distance even if you lose GPS signal. The SF-510 also has a built-in accelerometer that tracks your distance, pace, and calories while you are indoors. You can select the recall menu to view run data from past workouts. And the auto pause feature automatically pauses the data recording when you stop running.
