About the Zenith 03.3120.3600/76.M3100
The Zenith Chronomaster Sport 03.3120.3600/76.M3100 debuted in 2025. This watch is housed in a stainless steel case measuring 41mm across and 13.6mm in thickness, with softly faceted lugs, pump-style chronograph pushers, and a screw-down crown ensuring water resistance to 100 meters. A polished black ceramic bezel, engraved with the 1/10th of a second chronograph scale, frames the dial.
The dial is cut from a meteorite, giving each example a unique Widmanstätten pattern created by the crystallisation of the iron-nickel alloy. Applied faceted hour markers and rhodium-plated hands with Super-LumiNova provide legibility, while the overlapping tricolour registers at 3, 6, and 9 o’clock — in silver, light grey, and anthracite — carry over one of Zenith’s signature design codes. A date window is placed discreetly at 4:30.
Visible through the sapphire crystal case back is the self-winding El Primero 3600 El Primero 3600. This high-frequency chronograph movement operates at 36,000 vibrations per hour (5 Hz), allowing the central chronograph seconds hand to measure elapsed time with 1/10th of a second precision. The calibre is equipped with a column wheel and horizontal clutch, and it provides a power reserve of approximately 60 hours.
The Chronomaster Sport Meteorite is fitted with an integrated stainless steel bracelet with a folding clasp and delivered with an additional black rubber strap, allowing for versatile wear between a sporty and a more formal presentation.
