Ciga Design Series U

With Ciga Design Series U, the brand rethinks how we tell time with a distinctive watch. There are no hands: a three-dimensional engraved celestial body rotates at the center of the dial. Winner of the Challenge Watch Prize at the 2021 Grand Prix d'Horlogerie de Genève, the Ciga Design Blue Planet has become the collection's emblematic GPHG award-winning watch.

The collection explores this idea through several celestial bodies: Earth and its micro-engraved terrain on the Blue Planet and Atlantic, the lunar surface on the Moonwalker, and distinctive interpretations on the Ice Age and Black Star. Each model is powered by an automatic movement. The lugless case, made of titanium or mirror-polished 316L stainless steel, gives center stage to a domed sapphire crystal and comes on a rubber strap.

How do you tell time on a Blue Planet watch?

The Blue Planet is an automatic watch without hands. Its in-house CD-04-E caliber turns two elements at different speeds. The Earth disc advances 30 degrees per hour; you read the hour on the fixed outer ring at a compass-shaped marker. Meanwhile, the minute ring rotates 390 degrees per hour, a speed calculated so both indications always meet at that same marker. You only need to look at one point on the dial to read the hour and minutes. After a few days, it feels as natural as reading a conventional watch.

How is Earth's terrain engraved on the dial?

The Blue Planet dial is cut by a computer-controlled machine running at 20,000 revolutions per minute. An initial 18-hour engraving pass traces the contours to a precision of 0.07 mm. A protective layer is then applied before a second, 6-hour pass refines the topography to within 0.05 mm. Finally, a UV-cured lacquer adds color and depth. Up close, you can make out the Himalayas, the Great Rift Valley, and the Persian Gulf. The Moonwalker goes even further, with lunar terrain engraved to within 0.03 mm.
