By putting together the Tourbillon, the “Perpetual Calendar” and the El Primero chronograph, ZENITH has combined three legendary watchmaking complications, and is therefore able to propose a unique timepiece that only the Manufacture is capable of designing. The Perpetual Calendar is an ode to eternity: when wound, the El Primero 4033 movement, made with 492 components and 35 rubies, will display time, date, day, month and leap years accurately for a century, with no need for adjustment.
Time keeping is guaranteed by a set of intricately developed and carefully designed shafts encoding the months; moving parts that at times wait for years before getting into action at a precise moment. In one rotation for leap years, the chronograph hand will have had the pleasure of measuring 1,260,576,000 tenths of a second.So time is no longer an instant to be recorded, time we waste or time we do not have; this is generous and constructive; time that opens onto infinity.
