The Coros Apex Pro has garnered attention for its advanced features and robust performance, distinguishing itself from its predecessor, the Coros Apex. While both models share a solid foundation, the Apex Pro introduces enhancements that cater to specific needs of athletes and outdoor enthusiasts.

The original Coros Apex proved its mettle in various demanding scenarios, such as the Jordan Trail FKT and Dan Lawson’s LeJOG. Despite its resilience, a minor issue with the watch face arose, which was promptly addressed by Coros support. Opting for a DIY fix, the user transitioned to the Apex Pro, facilitated by an ambassador role with Coros UK.

Notable Enhancements

The Apex Pro stands out with additional buttons, improving usability, especially in cold weather conditions. While the Apex was already efficient, these extra controls enhance user experience in specific situations. The Apex Pro also offers an extended battery life, increasing from 35 to 40 hours in standard GPS mode, a critical feature for ultra-distance athletes.

Another addition is the altitude mode, which measures oxygen saturation levels. Although its utility may be limited for some runners, it adds value for those training at high altitudes. A future update promises comprehensive maps for navigation, further distinguishing the Apex Pro from its predecessor.

Performance and Precision

Despite potential bias as an ambassador, the Apex Pro's battery longevity and accuracy receive high praise. During a six-hour event along Italy's coast, the watch showcased remarkable precision on a complex 2km loop, aligning closely with official race metrics.

Customer Support Experience

Coros customer service has been commendable, demonstrating responsiveness and efficiency. In one instance, a watch with screen issues was swiftly replaced, leaving the customer pleased with the service provided.

Additional Functionalities

The Apex Pro retains the robust features of the Apex, including a workout mode that integrates seamlessly with a mobile app for customized training sessions. The interval builder is particularly useful for impromptu workouts, and the extended battery life reduces the need for frequent charging, even during high mileage weeks.

Choosing Between Apex and Apex Pro

The decision between the Apex and Apex Pro hinges on individual requirements. The Apex is a reliable option for marathon training and ultra-marathons up to 35 hours. However, the Apex Pro's potential for topographical maps and altitude monitoring may attract those venturing into extreme environments.

Ultimately, if the additional features and design of the Pro resonate with you, it could justify the investment. For those seeking a more feature-rich device, the Vertix 2 offers even greater capabilities, albeit at a higher price point.
