You probably don’t know this, but Timex was one of the first companies to ever try its hand at something akin to the modern smartwatches that have become so popular of late. While that happened more than two decades ago (!!!), Timex is still far from what we’d call a household name in today’s thriving wearable device industry.

The Timex Ironman 300 GPS also has its own optical heart rate monitor going for it, which is a pretty rare asset in the sub-$150 price bracket. What’s even more unusual is this thing’s mind-blowing battery life of up to 25 days on a single charge, although we’re obviously talking about the smartwatch’s endurance with the GPS functionality switched off. If you keep that feature on at all times, the best you can hope for is around 20 hours of uninterrupted use, which is roughly on par with many of the latest Wear OS smartwatches.

Of course, Timex is going with a simpler software platform… of some sort, focused primarily on providing all the information you need to stay fit and improve your health while not consuming too much power. The Ironman 300 GPS can do smartphone notifications as well, and like any good “sports-first” wearable device, it’s capable of easily surviving water immersion up to 30 meters, which means you don’t need to leave the smartwatch at home before going to the pool for a quick swim.
