A TIMELESS TRIBUTE

Heritage-inspired El Primero in a modern 38 mm classic with full calendar and moonphase finesse

- 

Zenith’s Chronomaster Original Triple Calendar revisits a rare 1970 prototype with striking fidelity, marrying vintage spirit and contemporary high-frequency engineering. Housed in a 38 mm stainless-steel case just under 13 mm thick, its balanced dial layout presents day, date, and month windows flanking a moonphase aperture, all beneath a slightly domed sapphire crystal that nods to mid-century aesthetics.
