Zenith Chronomaster Flyback 03.1250.4009/01.C946

The Zenith Chronomaster Flyback – Ref. 03.1250.4009/01.C946 showcases a sophisticated multi-complication chronograph presented in a commanding 42 mm stainless steel case, distinguished by a pristine silver-white dial with Roman numerals and integrated moonphase display. This reference harmoniously blends Zenith’s classical elegance with high-frequency El Primero performance, offering a refined yet mechanically complex timepiece for discerning collectors.

The robust case frames a silver dial featuring bold Roman numerals and a traditional tricompax layout: 30-minute chronograph counter at 12 o’clock, small seconds at 9 o’clock, and 12-hour counter integrated with the moonphase at 6 o’clock, alongside a discreet date indication. A tachymeter scale enhances its functional character, all protected beneath a glareproofed sapphire crystal.

At its heart beats the high-frequency El Primero Calibre 405 B, an automatic 36,000 vph chronograph movement with column wheel construction and flyback function, allowing instant reset and restart of the chronograph with a single push. This technical architecture ensures smooth operation and a power reserve of approximately 50 hours.

Paired with a black crocodile leather strap, this configuration embodies a dress chronograph with added poetic complexity — ideal for connoisseurs seeking refined aesthetics combined with mechanical distinction.
