Zenith El Primero Chronograph 02.0500.400/24

The Zenith El Primero Chronograph – Ref. 02.0500.400/24 celebrates the legendary high-frequency El Primero movement within a clean and functional 38 mm stainless steel case. Produced in the late 1990s to early 2000s, this reference captures Zenith’s chronograph expertise in balanced, timeless proportions suited for everyday sport-elegance.

The stainless steel case features a fixed tachymeter bezel, screw-down crown, and anti-reflective sapphire crystal. The black dial emphasizes legibility with luminous Arabic numerals and a classic tri-compax configuration: small seconds at 9 o’clock, 30-minute counter at 12 o’clock, and 12-hour counter at 6 o’clock, complemented by a discreet date window.

At its heart beats the iconic El Primero Calibre 400, an automatic high-beat chronograph operating at 36,000 vibrations per hour (5 Hz) with 31 jewels. The movement delivers exceptionally smooth chronograph response and a dependable 50-hour power reserve, reflecting Zenith’s pioneering legacy in automatic chronograph technology.

With 100 meters of water resistance, this configuration offers durability alongside its mechanical pedigree, appealing to collectors who appreciate heritage performance in compact, wearable dimensions.
