The two models in the Defy Extreme series welcome a new addition in early December.

The DEFY Extreme Jungle is the most striking model in the trio dedicated to different parts of the planet. The use of minerals and ornamental hard stones in watches is back in fashion along with other incredible 1970s trends like angular cases.

The novelty formally meets all the stylistic criteria, but stands out from the many watches that trace their roots back to the 1970s. The mineral gemstone isn't reserved for the dial here: tiger's eye is used on the pusher guards and the outer dodecagonal bezel. 

And all of this is combined with a case that boasts an impressive amount of facets. The model dedicated to the jungle has a titanium case with an extreme number of facets decorated with tiger's eye. Compared to the pale chalcedony seen on the icy DEFY Extreme Glacier and the falcon's eye on the DEFY Extreme Desert, the stripy tiger's eye looks stunningly bright.

The jungle style is reinforced by tinted green sapphire crystal used for the counters, encircled with tiger's eye.  The transparent counters draw attention to openworked elements of the automatic movement: the El Primero 21 (El Primero 9004 base movement) with a 50-hour power reserve.

In keeping with the jungle theme, the mainplate and rotor are finished in khaki green. Traditions of the legendary high-frequency El Primero live on in this caliber, which can clock up some serious speed. 

This movement's defining features are its two separate regulating organs and mainspring barrels. The balance responsible for timekeeping runs at a frequency of 36,000 vph, while the second one activated with the chronometer runs at 360,000 vph.

This allows the central chronograph hand to make one full circle of the dial every second and measure elapsed time with an accuracy of up to 1/100 of a second. The DEFY Extreme Jungle will be available as a limited edition of 50 pieces (the same limit set for the precious models decorated with minerals).
