History of the Rolex Cosmograph Daytona
Launched in 1963 as a new-generation chronograph, the Cosmograph soon gained the name that became the mark of an icon: Daytona. Designed as the ultimate tool for endurance racing drivers, the Cosmograph Daytona was robust, waterproof and featured a tachymetric scale on the bezel for calculating average speed.

Birth of a Horological Icon Timepiece The myth around the iconic Rolex Daytona has spread around the world recent years. Always has the Daytona model been attached to motor racing, at first Rolex called their new Cosmograph the “Le Mans” and little later to “Daytona” when Rolex started to sponsor the well known U.S. speedway.
Cosmograph: a name that was to be the forerunner of great fortune. Actually, the choice of the name proved to be neither easy nor expected. Whilst Rolex on the one hand flirted with the car-racing world, on the other hand it could not remain unaware of the vast media attention, which at that time was surrounding the conquest of outer space.
In 1988, Rolex introduced the 16520 reference at the Spring Basel Watch Fair. The most obviously ‘historical’ change is the switch from the former manual winding movement to the new automatic mechanism. And, aesthetically speaking, compared to the previous models it presented a totally new look.
It immediately became a highly sought after icon with Rolex enthusiasts. In fact it was the hardest chronograph to get on the market, and retailers had year-long waiting lists. The production of this model officially ended in 2000.
History of the Zenith El Primero movement
The Zenith El Primero caliber is one of the most iconic watch movements in the history of watch making. It was the first- or one of the first automatic chronographs produced in series. During the 1960s there were three parties competing to build the first automatic chronograph. The main players were a consortium of companies with mutual interests: Heuer, Buren-Hamilton, Breitling and Dubois-Depraz. In the Far East, Seiko was working on its own version. And then there was the dark horse from Le Locle: Zenith. Whether or not the so-called Chrono-matic group — Hamilton-Buren, Breitling, Heuer, and Dubois-Dupraz — or Seiko actually beat the El Primero to market is not important. What’s important is this: the Zenith movement that resulted seven years after the journey began in 1962 is arguably still the best automatic chronograph in its price range 44 years later. So that this was not forgotten, the movement was given the name “El Primero”
This movement was so well build that even Rolex used it for its Daytona series from late 80s to early 2000. The El Primero was a watchmaking marvel of its time — and not just for one reason. For one, the watch featured a column wheel chronograph with a tri-compax layout. Most chronographs at the time (and many today) utilized a cam-actuated chronograph. There are benefits and drawbacks of using both types of chronographs, but column wheel production is more complex and labor-intensive. That Zenith chose to utilize a column wheel chronograph shows the level of end-to-end watchmaking that went into the El Primero development.
The smooth sweep of the seconds hand is much beloved by watch wearers. Today, the balance wheel in most mechanical watches beats at 28,800 vibrations per hour (vph); if you look closely, that smooth seconds hand sweep is actually eight ticks per second. The El Primero, on the other hand, is what’s known as a high-beat movement, making 10 ticks per second, or 36,000 vph. Not only does this create a smoother sweep, it also allows the chronograph function to maintain accuracy down to 1/10 of a second. High-beat movements were rare in 1969, and they’re rare today. Even Rolex slowed the El Primero down to 28,800vph for the Daytona.
With more beats per hour comes increased wear and tear on the escapement. To counter this, Zenith developed special lubricants that would keep the El Primero on the wrist more often than in a watchmaker’s hands. The other critical deficiency of a “quick tick”, though, is the tendency to lose power faster than normal. Zenith made the solution look simple: they used a mainspring capable of a 50-hour power reserve. These are the sorts of decisions that have proven Zenith is unwilling to cut corners, and they’ve paid off in spades (and by spades, we mean millions of dollars and a cult following).
