El Primero Tourbillon
Regarded as one of the stellar horological complications, the tourbillon improves the precision of a watch by counteracting the gravity-induced disturbances affecting the regularity of the balance. Only a small number of watch manufacturers are capable of developing and producing this complex mechanism in-house. Zenith is one of them, and has been for almost a century, since the first tourbillon from the brand with the guiding star dates back to 1920.
Zenith, however, will never be satisfied with merely creating such a complication, however prestigious it may be.
The Zenith Manufacture
the world's only tourbillon
beating at a high frequency
Not content with merely mastering this complication, however prestigious, Zenith remained true to the enterprising spirit that has governed all its creations since the early days of its history by developing the world’s only tourbillon movement beating at a high frequency: the El Primero caliber oscillating at a rate of 36,000 vibrations per hour and ensuring the most sophisticated chronometric performance.
Moreover, since the brand’s creative boldness is equalled only by its horological virtuosity, Zenith tourbillons also incorporate additional complications within the tourbillon carriage: a small seconds for the models in the Captain Collection and a date for those in the El Primero Collection. These top-flight mechanical constructions are both duly patented.
Zenith tourbillons integrate additional complications into the structure of the tourbillon carriage
Whether in El Primero or Captain models, all Zenith tourbillons share a certain number of common denominators: an off-centered carriage rotating once a minute and revealed through an open dial; a high-frequency automatic caliber; as well as an over 50-hour power reserve.
