This elevated-frequency approach allows for finer stopwatch measurement resolution than conventional chronograph calibers.

This openwork treatment is a defining feature of the reference and one of its most admired design attributes among collectors.\"}},{\"@type\":\"Question\",\"name\":\"Is this a good buy, and how can I purchase it from Bizak \u0026 Co.?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The Zenith Defy 21 El Primero in ceramic is a highly regarded reference among modern chronograph collectors, combining genuine horological heritage with advanced materials and dramatic design.
