Introduced in 2022, the Zenith Defy Extreme is a beefed-up version of the Defy 21. The case measures 45mm across at a height of 15.4mm, and it is water resistant up to 200 meters. Inside ticks a self-winding El Primero 9004 movement, which can be admired through the see-through back as well as through front via the sapphire dial. Reference 10.9100.9004-1/23.I303 was added to the collection in 2022. Inspired by the Extreme E electric rally race in Neom, Saudi Arabia, this version has a forged carbon and titanium case, plus a strap made of recycled tyres.
