This high tech perpetual calendar with a dual time function and the legendary in-house developed and manufactured self-winding movement is the most consumer friendly perpetual calendar ever produced and has passed the tests of time. The striking aesthetic of El Toro combines modern materials with a timeless dial design that inspired its name. The bezel and pushers are made in ceramic. The squeletted hands permit easy reading of all calendar functions and the sapphire caseback allows to observe the mechanics of time.
