Zenith Chronomaster El Primero Steel — Black Sunray Open Dial | Ref. 03.2040.4061/21.M2040

Dressed in the deepest registers of the watchmaker's palette, the Chronomaster El Primero Open with its black-toned sunray-patterned dial makes an unequivocal statement about how technically demanding and visually commanding a single watch can be simultaneously. The 42 mm stainless steel case provides the structural foundation for Zenith's most acclaimed innovation — the El Primero 4061 calibre — while the open-dial aperture ensures that the beating heart of the chronograph is perpetually on view.

Against the black sunray surface, the cutaway window exposing the column-wheel assembly creates a dramatic chiaroscuro effect — dark dial interrupted by the burnished complexity of the movement beneath. It is a composition that rewards sustained attention, with each viewing revealing fresh mechanical detail. The automatic El Primero 4061 movement delivers the high-frequency chronograph with approximately 50 hours of power reserve, maintaining the hallmark precision that has made Zenith chronographs the reference point against which all others are measured since 1969.

The stainless steel bracelet integrates seamlessly with the case profile, its alternating polished and brushed surfaces picking up the dial's interplay of matte and reflective finishes. Water resistant to 10 ATM, this is a watch built to accompany its owner across every dimension of an active life. At $7,360, the black-dial Chronomaster El Primero Open stands as one of the most technically authentic and aesthetically compelling chronographs available at its price point.
