For pacemile running watches heart rate tracking, a chest strap is still the most reliable way to get steady readings on runs, rides, and gym sessions. The choice here is stark: a new strap with modern dual connectivity versus a used, older strap with a narrower feature set and a higher listed price.
Quick Verdict
If you want broad device compatibility and a new-in-box purchase, the Powr Labs Bluetooth and ANT+ Heart Rate Monitor Chest Strap - All Day Comfort at USD 18.99 is the more practical pick. It lists both Bluetooth and ANT+ and a 6-month battery life, and it covers Android, iOS, macOS, and Windows.
The Garmin HRM1G Wireless ANT+ Heart Rate Monitor Chest Strap HRM1G No Battery at USD 25.95 makes sense only if you specifically need a Garmin HRM1G replacement harness and already run an ANT+ only setup. It is listed as Used with scuffs and signs of use, includes only the strap and fabric harness, and comes with no battery.

Product Notes
Powr Labs Bluetooth and ANT+ Heart Rate Monitor Chest Strap - All Day Comfort

This strap is built around dual-mode heart rate measurement via Bluetooth and ANT+ with electrical sensor technology, which is useful if you switch between a running watch, bike computer, and phone apps. The description highlights indoor/outdoor use and all-day comfort for unisex adults, with a lightweight plastic build sized at 61-inch length, 1.5-inch width, and 0.15-inch height to accommodate different body types. A concrete reason to choose it is the combination of New condition and the lowest listed price at USD 18.99 with support for four operating systems. A limitation is that the listing focuses on core heart rate tracking via Bluetooth and ANT+ without detailing advanced running dynamics or additional on-strap features beyond the chest strap design.
Garmin HRM1G Wireless ANT+ Heart Rate Monitor Chest Strap HRM1G No Battery

This is a Used Garmin HRM1G Wireless ANT+ Heart Rate Monitor Chest Strap offered at USD 25.95, the higher listed price in this pair. The description states all functions have been tested and are in working order, but the units have some scuffs and other signs of use, and no batteries or other accessories are included unless shown in photos. A concrete reason to choose it is if you are replacing a lost or worn HRM1G and want the same model with its fabric harness. A limitation is the narrower scope in the listing: connectivity is shown as Chest Strap only without Bluetooth, operating system support is listed as Android only, and you will need to source a battery separately before use.
Final Choice by Use Case
- Choose the Powr Labs at USD 18.99 if you want a new strap that pairs widely via Bluetooth and ANT+, works across Android, iOS, macOS, and Windows, and keeps the listed cost at the low end of this comparison.
- Choose the Garmin HRM1G at USD 25.95 if you specifically need an HRM1G replacement and accept a Used, ANT+ focused strap with no battery included and a higher listed price.
For most shoppers looking for pacemile running watches heart rate coverage across watches, phones, and indoor training apps, the Powr Labs option covers more scenarios out of the box, while the Garmin option is a niche replacement buy.
