Defy Extreme 45 mm, titanium, self-winding caliber El Primero 21 with chronograph function | Reference Number ZN100015

The luxurious hundredths of a second chronograph Defy Extreme Carbon (Ref. 87.9100.9004/03.I001) combines craftsmanship and technical mastery with solid readability. In the 45-millimeter case made of titanium and rose gold, the beating heart of this fascinating watch can be seen from both sides through a skeletonized dial and a sapphire crystal caseback: self-winding manufacture caliber El Primero 21, which houses a second escapement for the chronograph functions. In this way, the "movement within a movement", with its own power reserve and manual winding mechanism, enables the measurement of hundredths of a second - and allows the central hand to circle around the dial extremely quickly, in just one second, when the watch is stopped. This exceptional timepiece with its sporty, technical design is fitted with a micro-blasted titanium bracelet that, thanks to the quick-change system, can be replaced in no time at all by the additional rubber strap or by the additional Velcro strap.
