Zenith Chronomaster El Primero Steel — Silver Sunray Open Dial | Ref. 03.2040.4061/01.M2040

The Chronomaster El Primero Open represents one of watchmaking's most celebrated pedagogical gestures: a window cut directly into the dial, revealing the column wheel and escapement of the El Primero calibre in motion beneath the hands. Since Zenith introduced this concept, it has become synonymous with the manufacture's philosophy of transparency — an invitation to look past surfaces and appreciate the mechanical reality underneath.

This 42 mm stainless steel example presents a silver-toned sunray-patterned dial that radiates outward with an almost solar authority. The El Primero 4061 automatic movement delivers chronograph function with the famous 36,000 vph beat that made Zenith's name in 1969, when it became the first manufacture to introduce a self-winding, high-frequency column-wheel chronograph. Approximately 50 hours of power reserve sustains that rhythm between windings. The integrated stainless steel bracelet closes the aesthetic loop with polished and brushed link surfaces that mirror the dial's interplay of light.

At 42 mm across, this Chronomaster occupies the sweet spot of contemporary wrist presence — authoritative without excess. Water resistant to 10 ATM, it requires no compromise between elegance and utility. Priced at $7,360, it remains one of the most technically compelling entry points into genuine haute horlogerie, offering the full El Primero experience with the enduring appeal of steel and silver.
