The Ultra Watch for the Ultra Runner. Inspired by and designed for the tortured souls who need more distance than a simple marathon can offer. This features a 100 hr chronograph, a 15 second EL Backlight for running in low light conditions, and a Hydration Alarm that let’s you know when to fill up on fluids. Other features include a 35 lap memory, 5 interval timers, 3 alarms, dual time and 10 run data storage (total time, best lap, average lap). Water resistant to 100 meters. Black and lime green silicone strap.
