We have managed to obtain exclusive images of Polar’s upcoming fitness wearable, the Polar H12 (model number 6M). As athletes and fitness tech enthusiasts constantly look for the most accurate training tools to pair with their GPS watches, this upcoming chest-worn heart rate sensor is shaping up to be a serious, direct rival to Garmin’s popular ecosystem of chest straps.
Redesigned for High-Intensity Athletic Performance

Based on the photos we received, Polar is keeping its core philosophy of reliable athletic monitoring while refining the hardware design for heavy training use. The newly surfaced pictures give us a complete look at the sensor pod, which comes packaged alongside a comfortable blue elastic textile strap. Unlike wrist-based optical sensors that can sometimes struggle with quick heart rate spikes during high-intensity intervals or heavy lifting, a dedicated chest strap like the upcoming Polar H12 aims to provide the absolute precision that runners and endurance athletes demand.
Hardware Specs: User-Replaceable Batteries and Connectivity

Looking closer at the hardware details revealed in the images, the back of the sensor pod confirms that Polar is sticking with a user-replaceable CR2032 coin cell battery. This is a massive win for athletes who hate dealing with proprietary charging cables or internal batteries running out of juice right before a big workout. Being able to quickly swap out a coin cell battery on the go keeps the device ready for daily training without downtime. Additionally, the side and rear views highlight a streamlined, low-profile build, clean curves, Bluetooth connectivity logos, and manufacturing stamps indicating it is built in Malaysia.
Pricing and Release Date Still Under Wraps
As of right now, no official details regarding pricing or a release date have been announced or leaked. Because these exclusive images have just come to light, we expect Polar to share more information regarding availability in the near future.
