The particular hour and minute means something different to every person depending on his obligations and habits, but the Closed Watch caters to a group of people that has one major concern in common. Rock climbers, mountain climbers and hikers are ever concerned with the timing of the sunrise and the sunset so that they can carry on their journeys by the safety of daylight.
What Seon-Il Kim, Hyun-Ju Park, Mingyeoung Baek and Mi-Jang came up with is a gradually darkening LED feature as the dial of the chronograph that's lead by the suggestion of its hour hand. As time goes by, the lighter wedge of the Closed Watch's face is consumed by this shadow, and the pale slice is the remaining sunlight for that particular spot and season.
