This 39.5mm stainless steel timepiece showcases Zenith's El Primero 3604 automatic chronograph movement through an open dial design. The movement operates at 36,000 vibrations per hour, enabling timing to one tenth of a second precision. The dial features a two-tone counter layout with a Hesalite subdial contrasting against the silver matte finish, complemented by applied steel indices and steel hands. A sapphire crystal provides protection, whilst the case offers 100 metres of water resistance. The watch runs for approximately 60 hours before requiring wind.
The stainless steel bracelet fastens via a secure foldover clasp, providing both comfort and functionality. This configuration balances legibility with technical specification, presenting the renowned El Primero mechanism as the focal point rather than obscuring it beneath a traditional dial. The 39.5mm proportions suit most wrist sizes without sacrificing presence or readability of the chronograph counters.
