Choosing running watches & heart-rate gear means deciding between a simpler route into run tracking and a watch with a broader set of training tools. Garmin's Forerunner 235 and Forerunner 165 both target runners, but their listed prices, conditions, battery claims, and feature emphasis create a clear split. The better choice depends on whether you want essential fitness functions or a more feature-heavy training companion.
Quick verdict
At USD 59.40, the Garmin Forerunner 235 is the practical choice when a lower entry cost matters. At USD 199.99, the Garmin Forerunner 165 fits shoppers who want more named display and training functions. The listed-price gap is USD 140.59, so match the extra capabilities to your routine rather than automatically choosing the costlier watch.

Product notes
Garmin Forerunner 235 GPS Running Watch

The Forerunner 235 suits a runner who wants a straightforward fitness watch rather than a long list of training extras. Its attributes include an alarm, calorie monitor, distance traveled, and indoor/outdoor use, giving it useful everyday scope beyond basic run timing. The description also calls out a colorful interface, which supports a simple day-to-day fitness focus. The limitations are specific: the unit is listed in used condition, visible light wear is mentioned on the strap and bezel, and a charging cable is not included. That makes the 235 a reasonable fit for shoppers comfortable with pre-owned gear and arranging a cable separately. Its combination of practical activity features and a lower listed price is the central reason to choose it.
Garmin Forerunner 165 GPS Running Watch

The Forerunner 165 brings a defined physical package alongside its running tools. The description specifies a bright 1.2-inch AMOLED touchscreen, a 43mm case, 39g weight, 25+ sport profiles, and 5 ATM swim-safe construction. Those details make it a fit for someone who wants an on-watch interface and broader activity coverage. A concrete limitation is the listed 43mm, 39g configuration: shoppers with a specific preferred case size or feel may find that setup less suitable. The watch also presents more features to learn and use, so its appeal depends on wanting that broader scope. Choose the 165 when the display and activity breadth are meaningful priorities rather than incidental extras.
Final choice by use case
Choose the Garmin Forerunner 235 for a straightforward everyday fitness setup and when the charging-cable trade-off is manageable. Its title's GPS running and heart-rate focus, along with the alarm, calorie monitor, and distance features, cover the basics without requiring the 165's wider feature set.
Choose the Garmin Forerunner 165 for marathon training or structured workouts. PacePro grade-adjusted pacing and Garmin Coach adaptive training plans are explicitly named, while HRV Running Power adds another training-oriented capability. For shoppers who want those tools and the AMOLED format, the 165 is the clearer match.
