<p>Reference 10.9100.9004/22.I200 is new for 2022. This Zenith Defy Extreme has a case in a combination of lightweight carbon fibre and titanium. </p> <p>Introduced in 2021, the Zenith Defy Extreme is a rugged take on the Defy 21. The angular case of the Zenith Defy Extreme measures 45mm across, at a height of 15.4mm. It is water resistant up to 200 meters. The robust lines of the case are echoed in the big and bold pushers. Like with the Defy 21, the movement inside is the El Primero 9004. This self-winding movement has a second escapement just for the chronograph action, which beats at 360.000bph. The movement can be seen both through the back as well as through the smoked-sapphire dial.</p>
