Zenith Academy Tourbillon Chronograph Limited Edition

The Tourbillon is one of the greatest horological complications, daring to defy the effects of the earth’s gravity by enclosing the escapement in a gyroscopic cage. Combining it with the El Primero movement ZENITH Manufacture engineered the fastest Tourbillon in the world – beating at 36,000 vibrations per hour this timepiece guarantees high precision with a chronograph accurate to a tenth of a second.

In order to transmit the necessary power to the high frequency tourbillon with the best possible result, ZENITH decided to keep a straight line escapement which means that the balance wheel is slightly off-centre in the cage. The ZENITH tourbillon therefore maintains the power of the El Primero, thus greatly improving an already remarkable precision.

These exceptional timepieces are available in 2 models. The first, with a 4005 movement, combines a tourbillon and a chronograph in a 45mm case, whilst the other, equipped with a 4041 movement, more sober because of its functions, concentrates the whole of its energy in the tourbillon and indicates hours and minutes. Housed in a 40mm case, it stands out particularly because of the oversized XI Roman numeral acting as the tourbillon bridge.

The model here featured is Academy Tourbillon Chronograph equipped with El Primero 4005 Calibre. Available in White Gold, with sapphire dial: Millesime & Numbered Edition. Available in White & Rose Gold with handmade guilloché dials: Limited Editions, 25 pieces & 50 pieces only.
