Information
Defy Xtreme Open Or & Titane or Defy Xtreme Tourbillon Zero-G
The TOURBILLON ZERO-G (zero gravity) is a major innovation in the world of watchmaking.
  
This   revolutionary system, which includes a gyroscope cage tourbillon and   constant horizontal escapement, means the mechanism avoids the effects   of gravity and thus gives considerably greater accuracy. 
Bringing   the Replica Tourbillon Zero-G and the Replica Defy Xtreme range together produces an   unforeseen design, a perfect alchemy of engine and odywork. A figure 8   on its side, symbolising infinity or a lucky number, is drawn around the   hours and minutes display at 11 o’clock and around the opening of the   phenomenal Tourbillon at 5 o’clock. A multi-layered dial of Hesalite   glass, carbon fibre and aluminium beneath two sapphire glasses, a   blackened titanium case that is waterproof at 1000 meters, a black   shot-peened titanium case, a protected crown, helium valve and titanium   bracelet with Kevlar inserts and high-temperature resistance are the   features that make this an extreme sports timepiece. A new star at the   zenith of the firmament, available in a numbered series and with the   millésime.
In the DEFY XTREME OPEN, the El Primero 4021 SX roars at 36’000   vibrations per hour, protected by a special blade on which the   3-branched second hand revolves.
    
The power reserve is   split into sectors, all hands have Superluminova® inserts.   Water-resistant to 1,000 meters, the case is in black titanium or in   black titanium and rose gold. A slightly raised helium valve allows for   decompression under extreme conditions; carbon fibre inserts make the   push-buttons special, multilayered dials combining honeycomb aluminium,   shock-resistant Hesalite and carbon fibre. The DEFY XTREME watches are   available on rubber strap or on bracelet blend brushed stainless steel   or rose gold and composite materials reinforced by Kevlar® lateral   inserts.
