Appreciate the present moment with the TACS Time Glass Crownless Watch. Drawing inspiration from the hourglass, Time Glass watches tell time in a simple yet elegant way. The Time Glass recreates the functionality and beauty of an hourglass by applying unique design elements. With a completely crownless design, the Time Glass offers optimal comfort by eliminating irritation and chafing. The crownless appearance mimics the side of an hourglass while the curved dial and hands represent a bird’s eye view. Additionally, the Time Glass uses exclusive Swiss movement by Ronda for reliability and accuracy. Setting the time is easy by simply pressing the adjustment button on the back of the watch. Finally, each Time Glass timepiece comes with a genuine leather and quick release strap.
