The Swiss watch Manufacture Zenith is presenting a new special edition of the revolutionary Defy El Primero 21. Launched at Baselword 2017, the Defy El Primero 21 stems from modern engineering, all designed to ensure simplified assembly and adjustment serving to achieve the finest level of performance and certification. The world’s most accurate series- made chronograph in 1969 entered in a whole new era with a frequency that reaches an impressive 360,000 vibrations/hour ensuring its hundredth of a second precision, and energy consumption is ten times higher than in the original. From tenths to hundredths of a second, a quantum leap in terms of performance and engineering. To avoid any risk of the chronograph interfering with the smooth running of the watch, the Defy El Primero 21 is therefore equipped with two independents “gear boxes”: one for the time (36,000 VpH - 5 Hz) and the other for the chronograph (360,000 VpH - 50Hz). Each has its own transmission and escapement system and there is no coupling clutch.
