The 1969 Chronograph Race

In January 1969, Zenith unveiled the El Primero — the first integrated automatic chronograph movement, beating at an unprecedented 36,000 vibrations per hour. Seiko and the Chrono-Matic consortium (Breitling, Heuer, Hamilton, Buren) were close behind, but Zenith claimed the title. That same year, the Omega Speedmaster — already a manually-wound chronograph since 1957 — was worn by Buzz Aldrin during the Apollo 11 moonwalk, cementing its place as the most famous watch in history. See our Omega Speedmaster Review and Zenith Chronomaster Sport Review for individual deep dives.

Design Comparison

The El Primero A384 Revival is a faithful recreation of the 1969 original — a 37mm cushion case with the signature tri-colour subdial arrangement (grey, blue, light silver) and a pump-style pusher design. At 37mm, it wears smaller and more vintage than most modern chronographs, which is part of its charm. The panda or reverse-panda dial combinations are stunning.

The Speedmaster Moonwatch Professional (2024+) is the current reference with the Caliber 3861. At 42mm with its Hesalite crystal (traditional) or sapphire sandwich option, it retains the classic Moonwatch aesthetic — step dial, dot-over-90 bezel, asymmetric case. It is the most recognised chronograph silhouette in watchmaking. Our TAG Heuer Carrera vs Speedmaster and Breitling Navitimer vs Speedmaster comparisons offer further perspective.

Movement: The Main Event

The El Primero 400 beats at 36,000 vph (5Hz) — still the highest frequency automatic chronograph in regular production. This enables timing to 1/10th of a second and gives the sweeping seconds hand an incredibly smooth motion. It uses a column-wheel with horizontal clutch, 50-hour power reserve, and is gloriously displayed through the exhibition caseback.

The Omega Caliber 3861 is a manually-wound movement — a deliberate choice that honours the Moonwatch heritage. It is METAS Master Chronometer certified with magnetic resistance beyond 15,000 gauss. The 50-hour power reserve matches the Zenith, and the Co-Axial escapement ensures longer service intervals. While the 3861 is technically simpler (hand-wound vs automatic, 21,600 vph vs 36,000), the METAS certification makes it arguably the more rigorously tested movement. A Moonwatch reference book is essential reading for Speedmaster enthusiasts.

Specifications Compared

Value and Legacy

The Speedmaster holds its value better on the secondary market (85-95% of retail vs 65-80% for the El Primero), thanks to NASA heritage, James Bond appearances, and Omega’s masterful marketing. The El Primero, despite its objectively superior movement specifications, depreciates more from retail — making it the better value for the informed buyer. Both are destined to be collected for generations. A quality dual watch winder is ideal for keeping both running in a collection.

Which Should You Choose?

Choose the Zenith El Primero A384 if you are a movement enthusiast who appreciates horological innovation. The 36,000 vph El Primero is objectively one of the most impressive chronograph movements ever made, and the 37mm vintage case size is perfect for those who prefer compact watches. At pre-owned prices, it is a bargain for what you get.

Choose the Omega Speedmaster Moonwatch if heritage, cultural significance, and brand prestige matter as much as specifications. There is simply no other watch with a story like the Moonwatch — it went to the moon and back. The METAS certification and Master Chronometer status add genuine technical substance to the legend. It is the chronograph that needs no introduction. Browse all watch comparisons.
