I chose this model primarily because of the Display Flasher feature. The LED that flashes during an alarm or on the hour is a brilliant addition that ensures I never miss an important notification, even when it’s noisy around me. The watch is also incredibly durable and solidly built, which you can feel right away when you put it on your wrist.
