After three years of research and development, Urwerk unveiled the world's first production wristwatch with true retrograde linear displays. Felix Baumgartner gleaned his inspiration for this horological endeavor from Patek Phillipe one and only prototype its 1958 King Cobra designed by Louis Cottier. Now after fifty years, Urwerk pays homage to this unique design. Another inspiration were the linear speedometers in old cars.
The retro case is over 47mm tall and 43mm wide. The seconds display ,in the upper window, is comprised of a large ultra-light disc and a spiral with Arabic numbers at the disc's edge. The progression of the seconds can be viewed in two ways: digitally and linearly: via a small window whereby every other second is displayed and via the spiral which seems to progress in a linear manner along the gauge. Two large cylinders display the hours and minutes in a retrograde manner. Both jumping hours and minutes spring back to the zero position once they are extended all the way..
Only 50 pieces have been produced: 25 pieces in 18k gray gold and another 25 in 18k black gold.
