I have been wearing this watch for about two weeks and I have recorded about 87 miles with it, including a 50-mile race.
The Bia watch is tiny (it weighs just over an ounce), but at the same time, it is easy to read. A quick glance down gives you all the information you need. The watch pairs with a “GoStick” that you clip on (see last picture below). The two-piece design keeps the watch simple, small and lightweight. There is only one button on the watch – but that’s all you need! There is also a touchscreen that allows you to perform all necessary functions.
The watch has an SOS feature – I think this is what makes it truly unique!! If you hold down the button on the watch for three seconds, it sends out an SOS! The SOS text message looks like this:
You cancel the SOS by holding down the button a second time.
Bia says the watch has a 17-hour battery life. I did not test the watch that long. However, I glanced down after 8.5 hours during my 50-mile race, and the battery indicator was already below the halfway mark (it started the race with a full charge). Does that mean the watch wouldn’t have lasted 17 hours? Not necessarily, but possibly.
Another great feature is you can set up the watch to automatically transfer your workout data to MapMyFitness or Strava.
Finally, the watch is waterproof and it comes in a variety of great colors!
