Within the PILOT collection, which reimagines the earliest ZENITH pilot watches and instruments as vintage-inspired wristwatches, the Type 20 Chronograph incorporates the El Primero automatic high-frequency chronograph calibre into a retro aesthetic. The easily legible dial with luminescent numerals and hands features two oversized counters for the running seconds and chronograph's minutes totalizer, all housed within a round and robust case with an oversized signature 'onion' crown.
