Making our best model better, Sentry has gone Solar. Our classic “thin black tie meets block party” timepiece just got an upgrade with limitless potential. 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. Custom, solid, stainless steel case and caseback pressure tested with a water rating of 10 ATM / 100m. The custom, stainless steel buckle adds strength to the band as does the perimeter stitching. Colour: Gunmetal Product Number: A1347 131-00
