About the Chronomaster Sport family
The Chronomaster Sport was introduced in 2021 as a 41 mm sports chronograph with a ceramic bezel graduated to a tenth of a second, matching the El Primero 3600 inside.
The catalog lists more than fifty references in steel, rose gold and steel and rose gold, with black or white dials and the tri-colour counters of the El Primero tradition, plus titanium and special editions. Dealers identify the metal and dial from the reference, check the bracelet and the condition of the ceramic bezel, and ask for the box and papers.
