See the Defy El Primero movement which flaunts standout performance: a COSC-certified in-house movement driving a hundredth of a second display by means of a central hand, with its unique and exclusive dynamic signature of one rotation per second.
Its double-chain structure is based on two regulators, made of Carbon-Matrix Carbon Nanotube composite, a patented new material that is insensitive to magnetic fields and temperature gradients to a degree well above existing norms.
With that said, I am among a large population of mechanical watch lovers who do care about accuracy. That there is still development in the traditional watch industry to make systems that actually pioneer new achievements in accuracy will be something that pretty much any watch collector can stand behind. I know that not everyone will be a fan of the aesthetic design of the Defy Lab, or the Defy El Primero 21 for that matter, but I think they will want the technology for sure. Zenith and LVMH now take a leading role in the pursuit of accuracy, how will the others respond? Attached to the case of the Defy Lab is a rubber strap with an alligator exterior lining and a titanium buckle. Price for the 10 piece unique Zenith Defy Lab reference 27.9000.342/78.R582 is 29,900 CHF each.
