A fragment of space now measures time on Earth. The Zenith Chronomaster Sport Meteorite, revealed at Geneva Watch Days 2025, incorporates an actual meteorite dial into the manufacture's most decorated contemporary chronograph. This edition transforms what was previously a Japan-exclusive release into a globally available model, bringing extraterrestrial material to the wrists of collectors worldwide.

The Chronomaster Sport earned the 2021 Grand Prix d'Horlogerie de Genève "Chronograph" prize, establishing its position in modern watchmaking. The meteorite variant builds upon this foundation, with each dial beginning its existence millions of years ago in space before ultimately arriving at Zenith's Le Locle workshop. The integration of cosmic material into a precision chronograph creates a tangible connection between terrestrial timekeeping and astronomical time scales, though the execution remains firmly rooted in practical watchmaking rather than conceptual design.

The 41mm stainless steel case maintains the established Chronomaster Sport architecture, with its pump-style pushers referencing the 1969 A386. The black ceramic bezel, graduated over 10 seconds for chronograph functionality, provides durability while enabling precise elapsed time measurement. Mixed finishing combines polished and satin-brushed surfaces across the case, while water resistance to 10 ATM ensures daily wearability. The case dimensions—13.6mm thickness and 47mm lug-to-lug—remain consistent with other Chronomaster Sport variants.

The meteorite dial represents the primary differentiation of this model. Hand-finished to reveal Widmanstätten patterns—geometric structures formed by iron-nickel crystals cooling over millions of years in space—each dial displays unique patterning. Zenith's signature tri-colour subdials in silver, light grey, and anthracite feature circular azuré finishing, providing visual contrast against the meteorite surface. Applied baton markers and hands receive C1 Super-LumiNova treatment, while the date window at 4:30 maintains the model's established layout. The natural variation in meteorite structure ensures no two dials appear identical.

The El Primero 3600 automatic movement continues unchanged, operating at five Hz (36,000 vibrations per hour) to enable tenth-of-a-second chronograph measurement. The silicon escape wheel contributes to the 60-hour power reserve, while the column wheel and horizontal clutch ensure smooth chronograph operation. Through the sapphire caseback, the blue column wheel, refined movement architecture, and star-adorned oscillating weight remain visible. The movement's specifications—including stop-seconds functionality and integrated chronograph construction—represent current Zenith chronograph technology.

The watch comes on an integrated stainless steel bracelet with alternating brushed and polished links, secured by a double-folding clasp. An additional black rubber strap provides wearing alternatives, particularly useful given the watch's sporty-chic positioning. Both options complement the meteorite dial's grey tones while maintaining wearing comfort expected from contemporary sports watches.

The Chronomaster Sport Meteorite occupies an interesting position within Zenith's catalogue. While the base model demonstrates technical achievement through its high-frequency chronograph, the meteorite dial adds visual distinction without affecting functionality. The use of authentic space material provides genuine differentiation in a market where dial variations often rely on colour or finishing alone. Previously restricted to Japanese markets, global availability suggests Zenith recognises broader collector interest in such materials.
