Zenith Chronomaster Triple Calendar

About this reference

The Zenith Chronomaster Triple Calendar in platinum, specifically reference 17.0240.410, was produced during the mid-to-late 1990s and early 2000s. Collectors target this reference for its 39mm case diameter and the El Primero Caliber 410, an integrated high-beat automatic chronograph movement featuring a full calendar and moonphase. This specific platinum execution is distinguished by its weight and a silver or blue sunray dial, often featuring applied rhodium-plated indices. Unlike the more common steel variants, the platinum version was produced in limited quantities, representing a high-end complication from the brand’s transitional era. On the secondary market, these pieces typically trade between $12,000 and $18,000 depending on the presence of the original platinum deployment buckle and service history. A notable production detail is the "Z" series or limited editions featuring chronometer certification, which often command a premium at specialized watch auctions.
