The Zenith 03.3100.3600/21.M3100 Chronomaster El Primero Sport Black combines classic chronograph styling with the advanced performance of the El Primero 3600 movement, whose central chronograph seconds hand completes a full rotation every 10 seconds for precise 1/10th-second measurement. This innovative design is enabled by a wheel coaxial to the escape wheel, allowing the chronograph to move six times faster than previous Cal.400 series models, while the irregular three-counter layout and extended 60-hour power reserve further enhance functionality. Its black dial, stainless-steel case, and black ceramic bezel create a modern, sporty look that retains Zenith’s heritage of high-frequency precision at 36,000 vph.
The watch is in very good condition, with the case showing slight scratches, the bezel remaining free of noticeable damage, and the bracelet displaying light minor scratches consistent with careful use. The buckle has slight marks, while the sapphire crystal is clean with no visible defects. Sized at 41 mm with a thickness of 13.8 mm, it fits wrists up to approximately 21 cm and maintains excellent wrist presence. Accessories include the manufacturer’s warranty dated January 2024, the original box, and a booklet.
