Zenith Cronometro Tipo CP-2 Flyback Bronze 29.2240.405/18.C801

The CP-2 name goes back to the 1960s, when A. Cairelli of Rome, official retailer to the Italian Army, commissioned the original chronograph from Zenith; about 2,500 were ordered between 1960 and the early 1970s, with the hand-wound calibre 146 DP. The 2016 Cronometro Tipo CP-2 (03.2240.4069/21.C774) revived the design in steel as a 1,000-piece edition with a closed back and no flyback.

The Flyback brought in Zenith's automatic El Primero 405 B, a 5 Hz column-wheel chronograph with a flyback function and a power reserve of at least 50 hours. The bronze case has a steel back, the dial darkens toward the edge, the hands are gold, and the bidirectional bezel carries a 60-minute scale. The Aged Steel / Slate (11.2240.405/21.C773) is the same watch in grey DLC-coated steel with a dark grey dial and steel hands. Neither is limited, and the case takes a 22 mm strap.
