Launched in 2026, the Zenith Chronomaster Solo Sport 03.5000.3620/21.M5000 presents a clean, no-date layout, distinguishing it from its three-hand Chronomaster Solo Sport counterparts. The watch features a sturdy 40 mm case crafted from stainless steel, paired with a polished black ceramic dial and bezel, providing a modern aesthetic. Notable for its additional protective elements, the case includes a screw-down crown and integrated crown guards, as well as a unidirectional rotating bezel made of black ceramic, all ensuring a water resistance of 200 meters.

The striking dial showcases a distinctive 45-degree Z pattern, unique to this collection, while the minute track exhibits the historical "shark tooth" segment style typical of Zenith's heritage. The hands and applied markers are enhanced with Super-LumiNova SLN C1 for low-light visibility. As a no-date model, the watch focuses solely on displaying central hours, minutes, and seconds. Inside, the timepiece is powered by the automatic El Primero 3620 caliber, a refined version of the El Primero 3600. Running at a robust frequency of 36,000 vibrations per hour, this movement ensures around 60 hours of power reserve, featuring a silicon escapement and a bidirectional winding system complemented by an openworked star-shaped rotor. The model is completed with a comfortable three-link stainless steel bracelet, secured by the ZENCLASP folding clasp, allowing for easy adjustments in 2.5 mm increments across a 10 mm range.
