Design and Build
The Garmin Forerunner 935 features a round, stainless steel case paired with a 22-millimeter silicone band, giving it a classic sports watch aesthetic. Its standout physical attribute is its weight, coming in at a mere 49 grams. This ultra-lightweight construction is a key selling point, designed to disappear on the wrist during long training sessions and remain comfortable for all-day wear, including recovery periods. The watch uses a tang buckle clasp for secure fastening.
The 1.2-inch LCD display provides a clear, always-on view of data with a resolution of approximately 240 by 240 pixels. Navigation is handled entirely through physical buttons, which can be advantageous for use in wet conditions or with gloves compared to a touchscreen. A notable design feature is the support for interchangeable QuickFit bands, allowing users to swap bands for different sports or styles. As a renewed product, it is important to note that individual units may show minor cosmetic signs of prior use, though owner reviews frequently mention units arriving in excellent condition.
Performance and Features
GPS and Sports Tracking
As a dedicated running GPS unit and triathlon watch, the Forerunner 935 is built for multisport athletes. It supports GPS and GLONASS satellite systems for accurate location tracking. The watch is designed for running, cycling, swimming, and general training. For swimming, its IPX7 water resistance rating means it can withstand immersion in up to one meter of water, making it suitable for pool sessions. The built-in barometric altimeter provides accurate elevation change data, while the electronic compass aids in navigation.
Health and Performance Metrics
A core strength of the Forerunner 935 is its advanced physiological tracking. The optical heart rate sensor on the wrist allows for continuous heart rate monitoring without a chest strap, though the data indicates compatibility with external straps for potentially greater accuracy. It provides dialed-in data such as running dynamics, cycling metrics, and swimming metrics. Crucially, it evaluates training status to indicate if you are undertraining or overdoing it and offers performance monitoring features like VO2 max estimates and functional threshold power (FTP) for cycling.
Smart Features and Connectivity
Beyond pure sports tracking, the watch offers smart notifications, delivering alerts from a connected smartphone directly to the wrist. It features automatic uploads of activity data to Garmin Connect and other platforms. A notable motivational feature is Strava Live Segments, which turns runs or rides into virtual competitions. The watch is compatible with Garmin’s Connect IQ platform, allowing for the installation of custom watch faces, data fields, and apps to personalize functionality. It connects to devices via Bluetooth for data syncing.
Setup, Support and Ownership
Setting up the Forerunner 935 requires pairing it with a smartphone and the Garmin Connect app to access the full suite of features, including performance metrics and smart notifications. The manufacturer’s description suggests there is an initial setup time to fully utilize all training metrics. As a renewed product, it comes with a 90-day limited warranty, which is a key consideration for buyers.
Ownership is enhanced by the ecosystem of accessories. The watch supports interchangeable QuickFit bands, allowing for style changes. It is also compatible with chest strap heart rate monitors for those seeking alternative biometric tracking, though these are not included by default. The device runs on Garmin’s proprietary operating system, and updates would be managed through the Garmin Connect ecosystem.

What Owners Say
Owner feedback for the Amazon Renewed Forerunner 935 is overwhelmingly positive, reflected in its high rating distribution where the vast majority of reviews are five stars. Buyers frequently praise the unit’s condition, with many noting it arrived looking almost brand new and functioning perfectly. The lightweight design and comfort for all-day wear, including during swimming, are consistently highlighted as major benefits.
Users appreciate the comprehensive feature set for training, citing good battery life and ease of use. A common acknowledgment in the reviews is that as a model originally released several years prior, it lacks some features found on newer watches, but owners consider it a great value for the price, especially in its renewed form. The sentiment is that it delivers excellent performance for dedicated athletic use without the premium cost of a latest-generation model.

Who Should Buy It (and Who Should Skip It)
The Amazon Renewed Forerunner 935 is an ideal choice for dedicated runners, triathletes, and multisport enthusiasts who prioritize in-depth performance analytics over the latest smartwatch features. Its lightweight build and comprehensive data suite make it perfect for athletes who train daily and want to monitor training status, recovery, and advanced metrics like VO2 max without a bulky device. It’s also a great fit for budget-conscious buyers seeking the capabilities of a high-end Garmin watch at a reduced price through the renewed program.
This watch is not the best choice for those seeking a general-purpose smartwatch with extensive app ecosystems, contactless payments, or music storage. Individuals who require the absolute latest features, a vibrant AMOLED touchscreen, or deeper smartphone integration should look at newer models. Similarly, those who are uncomfortable with the possibility of minor cosmetic imperfections inherent to renewed electronics may want to consider a brand-new unit.
