The story of the Zenith El Primero chronograph goes back many decades and involves a designer who’s unapproved designs & toolings were stashed in the attic at the Swiss manufacturer. The new 38mm Zenith Chronomaster Revival Manufacture Edition celebrates the unearthed design and mimics the brands’ iconic A386 model, featuring 3 overlapping subdials and a numerical date window. It is powered by the El Primero movement with a 50-hour power reserve.
