Expert opinion
The original Enduro gave ultra runners a watch that lasts up to 50 days between charges, or 65 days with solar, and records GPS for 70 hours, or 80 hours with solar. It introduced the ultrarun activity with a rest timer for aid stations, Trail Run VO2 Max and the trail version of ClimbPro. It has no maps, no music and no Wi-Fi, so navigation follows a breadcrumb course, and maps arrived with Enduro 2. The titanium version weighs 61g, which is the lightest of the four Enduro watches.
