Meet the Defy Inventor: Zenith's Most Ambitious Release to Date



If you've been following Zenith's release arc this year, you likely already know about the pitch-perfect El Primero re-issue box set, or maybe about the super-cool El Primero A384 heritage re-issue. But arguably, the most significant news this year out of Zenith's camp has been that of the new Defy Inventor – the direct descendent, and fully industrialized sequel to the ultra-limited, ultra high-frequency Defy Lab concept piece from 2017, whose 15 Hz movement was designed to make it the world's most accurate watch.



Only 10 Defy Lab watches were ultimately produced, but everything Zenith learned from that revolutionary technology has been applied to the new Inventor, which manages to increase the frequency rate and overall stability, and thereby accuracy of what was already an astonishingly accurate watch.

What made the Defy Lab – and by extension, the new Inventor special, is the Zenith Oscillator, which is a single silicon component that's been engineered to pull triple duty, integrating three of the watch's key elements: the balance spring, lever, and balance wheel, into just one entirely new element that vibrates at an incredible 129,600 beats per hour – 18 Hz, compared to the 15 Hz of the original Defy Lab.



For as often as we say a watch must be seen in the metal to be fully appreciated, the Zenith Defy Inventor's ultra high-frequency Cal. 9100 movement beats in a frenetic manner that simply must be seen to be believed. To do just this, we invite you to join us on August 1st at 6:30pm as Topper and Zenith host a Watchthebay meetup, where guests will have a chance to go hands-on with the radical new Defy Inventor and peer through its dramatic openworked dial, as well as check out the El Primero A384 heritage re-issue. Speaking of the El Primero, we'll have refreshments, a special raffle for attendees, and will be hoisting champagne to celebrate the legendary movement's 50th Anniversary, and we'd love to have you join us. Click here to RSVP to guarantee your spot, as all summer, our WatchtheBay-hosted events have been immensely popular, and fill up quickly.
