When you need battery life, nothing beats this watch. Also has advanced training tools and mapping. Smartwatch to training, a great choice. The only downsides are no music and no GPS tracking for an emergency contact.
Transitioned to the COROS APEX to help with training for Fall races. Incredible battery life, easy to use app and web interface, and tons of highly useful data you can use to help reach your goals. Great for tracking sleep and recovery, too!
