With one look, it is abundantly obvious that every luxury timepiece in Zenith's Defy Xtreme series is the most rugged, bulletproof and downright awe-inspiringly massive ever created. With a full 1,000 meters (3,300 feet) of water resistance, this is truly among the most element-impervious timepieces on the market today.
All Zenith watches in the Defy Extreme series feature cases of titanium, a very light, but extremely strong metal well known by divers for its ability to resist deformation under severe pressures. Depending on the watch, cases might also include solid 18k rose gold, silver or stainless steel embellishments. An ultra-hard, domed glare and scratch-resistant sapphire crystal protects a dial displaying several of a range of complications in various layouts, with options including a tourbillon, the classic chronograph trio of 60-second, 30-minute and 12-hour counters, a magnified date window and a power reserve meter. Some versions of this magnificent wristwatch feature a large window on the dial that exposes the gyrating balance wheel.
Driven by the unfailingly accurate Zenith-designed and manufactured 4021 series movement, the Defy Xtreme's hours, minutes and seconds luminescent hands allow time readings under even the murkiest conditions. A massive crown protector fortifies the crown against any type of blow directed at it. The crown guard also bestows protection upon the large chronometer operation buttons situated directly above and beneath the crown. Even when depressed under multiple dozens of atmospheres of underwater pressure, no water will enter the watch.
Finally, for the watch connoisseur who must have it all, the Defy Xtreme Zero-G, carries a tourbillon mounted in a gyroscope that moves freely on all axes, an horological engineering feat practically unheard of, and rarely, if ever seen.
