Zenith El Primero Chronomaster Ceramic Skeleton Dial

Introduced around 2018, the Zenith 49.2520.400/98.R578 Chronomaster El Primero Skeleton in black ceramic is a bold testament to Zenith’s high-frequency chronograph legacy. Its 45 mm ceramic case and skeleton dial deliver a modern, technical aesthetic that showcases the famed El Primero 400 B movement, a 5 Hz automatic chronograph caliber with 31 jewels, 326 components, and roughly 50 hours of power reserve. The openworked dial reveals the column-wheel chronograph architecture, with 30‑minute and 12‑hour subdials, small seconds, and a date display—highlighting both form and function. The ceramic construction not only gives the watch a striking matte-black presence but also offers lightweight durability and scratch resistance. With a water resistance of 50 meters, it balances sporty utility with haute horology appeal. The grey skeletonized dial elements, ruthenium‑plated faceted hands and indices with luminescent fill, and red-tipped chronograph hand underscore its technical refinement. Though not a limited edition, its distinctive execution and use of ceramic make it a standout in the El Primero line, appealing to collectors who value both the movement’s heritage and avant-garde design. Excellent condition with Zenith box and papers dated 2016.
