The Coros Apex 4 is the brand’s entry-level superwatch and an excellent choice for runners who prioritize performance over extra smartwatch features. If you’re looking for contactless payments, a deep app ecosystem or a bright AMOLED display, the Apex 4 probably isn’t the watch for you. However, if your priorities are long battery life, accurate tracking and rugged durability, it’s one of the best values available. Fortunately, Coros also offers a 42 mm model, although you have to trade in some battery life, losing about 20 hours of GPS time. The MIP screen also helps deliver greater battery life, making it one of the easiest compromises to accept.
