Suunto, a long time GPS player with a focus on mountain activities and scuba, launches its first wrist heart rate multi-sport and triathlon focused watch. Featuring the well-regarded Valencell heart rate monitoring technology, the Spartan Sport is light and comfortable on the wrist despite its thickness and weight (74g). Handmade in Finland with a full steel bezel unlike lighter competitors, it has a playful yet sophisticated look and interface. The Spartan has a very strong 100-meter depth water pressure rating and phone notifications, but no music control.
t leaves out the more accurate barometric altimeter of the Spartan Ultra but does include GPS based altitude stats. Suunto likes to provide lots of on-the-run data per customizable screen, 4 to 5 data fields. To make all that data readable the Spartan Sport has a 320 by 320 display resolution topping the new Garmin Fenix 5X’s 240 by 240. We found all that data very sharp and readable in bright sunlight, even with sunglasses on by tilting the wrist to catch the sun or by changing the display theme to a white background. In our initial testing distance, average and lap pace calculations, and heart rate were consistent and generally matched others in its class.
