Swiss watchmaker Zenith has just unleashed the DEFY Extreme, which features a sapphire dial with gorgeous depth and contrast and an El Primero 9004 automatic movement with a rugged 1/100th of a second automatic chronograph and 50 hours of power reserve. It's all housed in a 45mm micro-blasted titanium case available in a trio of finish options.

It's finished with a new strap mechanism for swapping in and out the supplied titanium bracelet, rubber strap, and velcro strap with no-tool ease. Go big — and bold — with one in the collection here.
