Choosing running watches & heart-rate gear comes down to one practical decision: do you want a GPS watch that puts tracking and heart-rate information on your wrist, or a focused chest strap built around torso-worn monitoring? The Garmin Forerunner 235 and Garmin HRM1G address those needs in distinctly different ways.
Quick verdict
The Garmin Forerunner 235 is the better fit for runners who want GPS, wrist-based heart-rate monitoring, distance tracking, and a watch interface in one device. The Garmin HRM1G is the more focused choice for someone specifically seeking a wireless ANT+ chest strap. The listed prices are USD 59.40 for the Forerunner 235 and USD 25.95 for the HRM1G, so the decision is also between a broader watch feature set and a dedicated strap format.

Where each product wins
- Garmin Forerunner 235: It wins for a watch-centered running setup, with GPS, a colorful interface, wrist-based monitoring, distance tracking, and smart notifications when paired with a compatible smartwatch.
- Garmin HRM1G: It wins when the priority is the torso-worn chest-strap format. Its Wireless ANT+ wording makes its intended role clear, without adding the broader watch features associated with the Forerunner 235.
Product notes
Garmin Forerunner 235
The Garmin Forerunner 235 suits a runner who wants the watch itself to handle GPS, wrist-based heart-rate monitoring, distance traveled, and calorie tracking. Its alarm and colorful interface add practical reasons to use it as the central device, while smart notifications are described when paired with a compatible smartwatch. That combination is the concrete reason to choose it over a dedicated strap format. The limitation is its used condition: visible light wear is called out on the strap and bezel, and the charging cable is not included. The watch is also identified with a silicone strap and plastic housing, details that reinforce its straightforward wearable design. Choose the Forerunner 235 for its GPS running-watch format, but account for the cable omission and visible wear.
Garmin HRM1G
The Garmin HRM1G is the better fit when the deciding detail is a torso-worn chest strap. Its title specifies a Wireless ANT+ heart-rate monitor, and it includes one chest strap with a fabric harness. That gives it a focused accessory role for runners who prefer a strap rather than a wrist device. Its limitation is the package condition: no battery or other accessories are included unless shown, while scuffs and other signs of use are noted. The attribute set also identifies Android under operating-system support, a concrete detail for shoppers whose setup uses that platform. Choose the HRM1G for its chest-strap construction and Wireless ANT+ format, while recognizing that its role is narrower than the GPS watch format of the Forerunner 235.
Final choice by use case
- For GPS-led runs and watch-based tracking: choose the Garmin Forerunner 235. The GPS running-watch title, wrist body area, distance feature, and heart-rate monitor align with a self-contained running device.
- For a torso-worn heart-rate accessory: choose the Garmin HRM1G. The Wireless ANT+ Heart Rate Monitor Chest Strap title phrase and torso body area directly match that use case.
- For a broader on-wrist feature set: choose the Forerunner 235 for its alarm, calorie monitor, colorful interface, and smart notifications.
- For a dedicated strap format: choose the HRM1G, provided the absence of a battery and other accessories suits your setup.
