Technical specification

Vantage M2

Battery type:

230 mAh Li-pol rechargeable battery

Operating time:

Battery life up to 40h in training mode (GPS and wrist-based heart rate) or up to 7 days in watch mode with continuous heart rate tracking. Multiple power save options available.

The multiple power save options bring you even up to 100 hours in training mode.

Operating temperature:

-10 °C to +50 °C / 14 °F to 122 °F

Device materials:



USB cable materials:


Watch accuracy:

Better than ± 0.5 seconds / day at 25 °C / 77 °F temperature

GNSS accuracy:

Distance ±2%

Average route accuracy: 5m

These are values that are achieved in open area satellite conditions when there are no apartment buildings or trees blocking the satellite view. In urban or forest areas these values are achievable but may sometimes vary.

GNSS recording rate

1 second (can be changed to 1 minute or 2 minutes in power save settings)

1 m

Ascent/Descent resolution:

5 m

Maximum altitude:

9000 m / 29525 ft

Heart rate measuring range:

15-240 bpm

Current speed display range:

0-399 km/h 247.9 mph

(0-36 km/h or 0-22.5 mph when measuring speed with Polar stride sensor)

Water resistance:

30 m (suitable for swimming)

Memory capacity: 

Up to 90 hours of training with GPS and heart rate depending on your language settings


Always on color display. Hard-coated PMMA laminated lens. Size 1.2”, resolution 240 x 240.


Uses wireless Bluetooth® technology.

The radio equipment operates 2.402 - 2.480 GHz ISM frequency band(s) and 5 mW maximum power.

The Polar Precision Prime optical heart rate sensor fusion technology uses a very small, safe amount of electric current on the skin to measure the contact of the device to your wrist to enhance accuracy.

Water resistance of Polar products

Most Polar products can be worn when swimming. They are not, however, diving instruments. To maintain water resistance, do not press the buttons of the device under water.

Polar devices with wrist-based heart rate measurement are suitable for swimming and bathing. They will collect your activity data from your wrist movements also when swimming. In our tests, however, we found that the wrist-based heart rate measurement doesn’t work optimally in water, so we cannot recommend wrist-based heart rate measurement for swimming.

In the watch industry, water resistance is generally indicated as meters, which means the static water pressure of that depth. Polar uses this same indication system. Water resistance of Polar products is tested according to International Standard ISO 22810 or IEC60529. Every Polar device that has water resistance indication is tested before the delivery to stand water pressure.

Polar products are divided into four different categories according to their water resistance. Check the back of your Polar product for the water resistance category, and compare it to the chart below. Please note that these definitions do not necessarily apply to products of other manufacturers.

When performing any underwater activity, the dynamic pressure generated by moving in water is greater than the static pressure. This means that moving the product under water subjects it to a greater pressure than if the product were stationary.
