Now equipped with a solar cell and Lum tip skeleton hands. Wear it for one hour under office lights to power an entire day, or expose it to six hours of direct sunlight to store six months of charge! Tap into a piece of Nixon heritage with Sentry Solar, now engineered for a brighter tomorrow.- Design: A Nixon classic, we’ve updated our best model for the future. Sentry Solar features a semi-transparent dial to allow this watch to absorb light for power with an enhanced sunray finish and a framed date window—it’s the little things that make a big difference.
