Epson Runsense SF-810, impressive accuracy

Epson has introduced three models as part of its line of Runsense sport watches, hoping to make its way on the crowded wearable market. Starting with the entry-level watch, called SF-510, and costing approximately 250 dollars, the midrange SF-710 at the price of 280 dollars and the last one is a high-end wearable, SF-810, and can be found at the price of 350 dollars.

Today we are talking about Epson Runsense SF-810, the high-end watch. Even if all three versions come with approximately the same features, the new SF-810 comes with a built-in optical heart-rate sensor.

Epson Runsense SF-810 is able to run for longer distances without a charge and is also keeping impressive heart rate tracking. To be clear, Espson’s Runsense models are not smartwatches or activity trackers. These new watches are considered to be GPS-equipped running watches.

While all three are capable of tracking distance and pace, only SF-810 is able to measure users’ beats per minute, due to its optical heart-rate sensor located on the back. Sadly, this new watch don’t come with some interesting functions and is designed only for runners. Epson Runsense SF-810 does not feature a specific mode for cycling or swimming, but users are able to measure distance and speed on a bike when the GPS is on.

Even if it comes with an accelerometer, Epson Runsense SF-810 is not able to measure the distance walked, steps taken or calories burned throughout the day. To be mentioned that the accelerometer function is only used as a GPS substitute to measure distance when GPS signals are unavailable. 

The new Epson Runsense SF-810 is not designed to be worn all day, especially on a costume. However, it is very comfortable to wear, it’s very lightweight and is coming with an interesting strap design, featuring a spring-like mechanism.

It has a bulky body, which can be a real attraction for every customer. Epson Runsense SF-810 is packed with functions that can be found on every normal watch, like displaying the time and date. However, the heart-rate monitor makes it easy to measure, control and monitor the intensity of user’s workouts.
