This timepiece boasts a high-frequency chronograph capable of measuring 1/100th of a second, thanks to its dual escapements operating at 5Hz and 50Hz. Encased in lightweight titanium, it features a striking open-worked dial that reveals the intricate mechanics within. With its modern design and exceptional functionality, the El Primero 21 stands as a testament to Zenith's horological expertise. The watch although normally paired on a leather strap, is featured on the Rubber Strap found on the 95.9000.9004/78.R782 model. (95.9000.9004). This watch is in good pre-owned condition, displaying light sign of wear that come with being lived with. Mostly superifical marks that could be refinished upon request. The watch includes the original inner/outer box, and papers dated 2017.
