The more expensive Polar watches do have more durable designs and longer battery life, but the Vantage M3 will still last up to seven days in watch mode, and offers 30 hours of workout tracking. It has a Gorilla Glass screen and a steel bezel, and a 1.28-inch AMOLED display that’s a little smaller than the 1.39-inch screen on the Vantage V3.

Polar announced its latest sporty smartwatch, the Vantage M3, with a 1.2-inch AMOLED display protected by Gorilla Glass to reduce nicks and scratches. The device features Polar's "next-gen" Elixir biosensors, bringing SpO2, heart rate, ECG, and skin temperature data.

The Polar Vantage M3 is built for multi-sport athletes who want the latest technology to train smarter and recover better – without breaking the bank.

Building on the success of previous Vantage models, most notably the Vantage V3 and the Vantage M2, the Polar Vantage M3 integrates advanced biosensing technology, including wrist-ECG, blood oxygen saturation measurements, and nightly skin temperature tracking.

The new Vantage M3 brings flagship performance and recovery tools to the masses with a form factor that appeals to that same group of people.
