Garmin and Coros are two brands known for making lightweight, stylish sport watches that appeal to athletes and fitness enthusiasts. These watches feature bright AMOLED screens, heart rate sensors, powerful mobile apps, and advanced tools for tracking training progress. Unlike popular smartwatches from Apple, Google, and Samsung, the Garmin Forerunner 170 and the Coros Pace 4 offer significantly longer battery life—up to twice that of standard smartwatches—requiring a recharge only once per week. Both brands also allow users to access their fitness data directly through their websites, making it easier to view trends, create training sessions, and analyze reports without relying solely on a smartphone app. The Garmin Forerunner 170 has a 1.2-inch AMOLED screen with a resolution of 390 x 390 pixels. It weighs 41 grams with the band and measures 42.6 x 42.6 x 11.9 mm. It has a battery life of up to 10 days when the always-on display is off, and 4 days when it's on. It can last 14 hours with GPS enabled and includes 4 GB of memory. The watch costs around 300 euros. The Coros Pace 4 has similar specifications, with a 1.2-inch AMOLED screen, 390 x 390 pixels, and a slightly lighter weight of 40 grams with the band. It measures 43.4 x 43.3 x 11.8 mm and has a longer battery life of up to 19 days with the always-on display off, and 6 days with it on. It can last 24 hours with GPS enabled and also has 4 GB of storage. The Coros Pace 4 is priced at 270 euros, making it slightly more affordable than the Garmin model. The Garmin Forerunner 170 has a traditional five-button layout, which allows users to navigate the watch using physical buttons. This can be especially useful in harsh weather or when sweating, as touchscreens may not always be reliable. These buttons can also be customized for quick access to favorite features or activities. If a user already owns other Garmin products—like screenless bands or heart rate monitors—the Forerunner 170 is a good fit due to its compatibility with the Garmin ecosystem. It also supports Garmin Pay, allowing users to make purchases directly from their watch, and offers access to thousands of customizable apps and widgets through the Garmin Connect IQ store. The Coros Pace 4 stands out with its use of five global satellite systems and a dual-frequency GNSS chipset, which provides more accurate location tracking than the Garmin Forerunner 170’s single-frequency GPS. This accuracy is especially useful during training events like 5 km or half marathons. The Coros Pace 4 also has a superior battery life compared to the Garmin model. It includes a keychain adapter for easy charging with a standard USB-C cable. Additionally, Coros offers a free, high-performance Training Hub app that allows users and coaches to create personalized training plans and manage teams through the Coros smartphone app. The choice between the Garmin Forerunner 170 and the Coros Pace 4 ultimately depends on the user’s preferences and existing tech ecosystem. If a user already uses Garmin products, the Forerunner 170 may be more convenient. However, users might prefer Coros for its interface, battery life, and training tools. For those with thinner wrists, the Garmin Forerunner 170 Music model (priced at 350 euros) might be a better option, as it includes music storage, the ability to pay for snacks during runs, and continues to support the Garmin ecosystem.
