Is Suunto about to replace its current chest strap now that the unannounced SHRM2 heart rate monitor has cleared the FCC?
The device surfaced in a US Federal Communications Commission filing under the model name SHRM2, according to Notebookcheck. The documents point to a Bluetooth Low Energy heart rate belt with a replaceable CR2032 battery and 30-meter water resistance.
Did Suunto announce SHRM2, or did the filing expose it first?
Suunto has not formally announced the SHRM2. The product appeared through regulatory documentation, not through a launch page, retail listing, or company press release cited in the available source material.
That matters because the FCC filing confirms only a narrow slice of the product. It shows the device exists as a wireless product intended for certification in the US. It does not give Suunto’s final marketing name, price, launch date, or full feature list.
The form factor is the clearest reveal. The SHRM2 appears to be a chest strap-style heart rate monitor, not a wrist wearable or optical armband. Gadgets & Wearables reported that Suunto describes the device as a heart rate belt in testing material, with regulatory information printed on a circular battery cover similar to the current chest sensor.
That places the filing in a familiar pre-launch category: enough to confirm direction, not enough to confirm the product story. MLXIO has seen the same partial-reveal dynamic across consumer hardware, from phone leaks like 3.5-Inch HMD Fame Leak Bets Tiny Phones Aren’t Dead to availability surprises such as US Gets Skipped as DJI Osmo Pocket 4 Pro Goes Global.
Which SHRM2 hardware details escaped through the FCC record?
The filing points to three practical details: Bluetooth Low Energy, a replaceable CR2032 coin-cell battery, and 30-meter water resistance.
The Bluetooth detail is especially relevant because the source material says the SHRM2 supports Bluetooth Low Energy, suggesting Suunto is moving to a newer Bluetooth implementation for its heart rate belt. Gadgets & Wearables adds that testing covered the 2402 to 2480 MHz frequency range and both 1 Mbps and 2 Mbps modes.
The battery change is more concrete. The SHRM2 label confirms a replaceable CR2032 cell. Suunto’s current Smart Heart Rate Belt uses a smaller CR2025 cell, and Gadgets & Wearables cites an official battery life estimate of around 500 hours for that existing model.
A larger battery hints at possible runtime gains, but that is not the same as an official rating. The new electronics, transmission behavior, and any onboard storage features would affect real-world battery life. The filing does not settle those points.
| Detail | Suunto Smart Heart Rate Belt | Suunto SHRM2 filing |
|---|---|---|
| Battery | CR2025, around 500 hours cited for current model | Replaceable CR2032 |
| Water resistance | 30 meters | 30 meters |
| Form factor | Chest heart rate belt | Chest heart rate belt |
| Wireless detail | Not detailed in the supplied source material | Bluetooth Low Energy |
The 30-meter rating matches Suunto’s existing belt. Notebookcheck says that points to continued swim compatibility, though Suunto has not yet published the SHRM2’s final product page or user manual in the supplied material.
Does SHRM2 look like a Smart Heart Rate Belt replacement?
Yes, based on the available reporting, the SHRM2 is expected to succeed Suunto’s current Smart Heart Rate Belt.
That is the cleanest read of the filing. Suunto already sells a chest-strap heart rate belt, and the SHRM2 appears to keep the same core category while updating the radio and battery format. Analysis: this looks less like Suunto entering a new accessory segment and more like a long-delayed refresh of an existing one.
The source material also gives one competitive marker. Notebookcheck names the Polar H10 and Garmin HRM 200 as comparable heart rate belts for users of other smartwatches. That does not prove Suunto is targeting those products directly, but it frames the SHRM2 in the same chest-strap accessory category rather than as a watch-first sensor.
There is one important omission: the public documents do not mention ANT+, according to Gadgets & Wearables. That may mean the SHRM2 remains Bluetooth-only, but the filing is not detailed enough to rule out other wireless modes before the full manual appears.
The same caution applies to simultaneous Bluetooth connections. The available filing does not confirm whether the SHRM2 can transmit to more than one device at once. For athletes using a watch and a second display, that will be one of the most practical specs to check when Suunto publishes the final documentation.
Which SHRM2 answers may stay hidden until January 2027?
The biggest missing pieces are still behind confidentiality. Gadgets & Wearables reports that the external photos, internal photos, and user manual remain confidential until January 19, 2027.
That date does not guarantee a launch window. Suunto can release documents earlier if it announces the product before then. But if the company stays quiet, the public record may remain thin for months.
The next documents or pages to watch are straightforward:
- Official name: Whether SHRM2 is the retail name or only the model code.
- Battery life: Whether the CR2032 translates into a higher rated runtime.
- Wireless modes: Whether Suunto confirms Bluetooth-only operation or adds other protocol support.
- Connection behavior: Whether simultaneous connections are supported.
- Compatibility: Which Suunto watches and apps are listed.
- Launch timing: Whether support pages, app updates, or retailer pages appear before the confidential files open.
For current Suunto users, the practical read is simple: the Smart Heart Rate Belt may soon have a successor, but the SHRM2’s strongest buying arguments are not public yet. Anyone choosing between the existing belt and waiting for the new one should watch for Suunto’s official spec sheet, because the FCC filing confirms the direction — not the full product.
The Bottom Line
- FCC approval suggests Suunto is moving closer to launching a new chest strap heart rate monitor.
- The filing confirms practical details including Bluetooth Low Energy, a CR2032 battery, and 30-meter water resistance.
- Key details such as price, launch date, final name, and full feature set remain unconfirmed.
