- The Zenith El Primero movement celebrated its 50th birthday in 2019. In commemoration of this momentous milestone, the manufacturer revived two original models driven by this movement, the rounded A286 and the tonneau-shaped A384, with several exciting re-editions.

- The present “Edge of Space” anniversary model is a revival of the latter and is the result of an alliance with Bambford and Mr. Porter. Having worked together in 2018 on the reinterpretation of the vintage Heritage 146, this newer model was highly anticipated among collectors and was instantly sold out upon release.

- With the A384 "Edge of Space", the design dramatically altered the overall aesthetics of the watch to achieve an incredibly modern and eye-catching rebirth of one of the greatest classics of the brand. The entire case, including its crown, pushers and buckle, are fashioned from sandblasted titanium, and the matte dial itself is midnight blue with black subsidiary dials.

- Offered in "like-new" condition and complete with its original accessories, the present timepiece is numbered 3 of a limited edition of 50 pieces and will delight both novices as well as the most seasoned collectors.
