Marc TRAN is student designer in Master Degree in product design and Management at International School of Design in Valenciennes (France). He submitted his new watch concept called Ringen. It is made with white gold for the structure and black magnetic ceramic for the slats and the balls. This watch is inspired by ball, game and automotive shapes. Marc worked with repetition and progression as we can see in architecture or furniture design . The mechanism to watch the time is mainly magnetic. Indeed, hours are shown by the blue disc in brushed aluminum anodized. Minutes are represented by the black ceramic slats. Each slats represent 2 minutes. It is an horizontal progression. The blue ball is moving on the slats to show what time it is. Seconds are shown by the other blue ball who is turning around the mechanism. It makes a turn in one minute.
