List of Rolex Calibers: A Complete Guide to Rolex Movements

When it comes to watchmaking and makers of movements for watches, Rolex is one of the most respected and established watchmakers in the world.

No, Rolex isn’t known for creating the most beautiful movements, but it’s known for creating some of the most reliable and robust movements in the world that keep ticking year after year, with reliable and high precision.

Rolex is one of few watchmakers that have all of their movements passed COSC, and it’s a producer of movements that have created calibers that have proven to withstand time.

Rolex calibers have been manufactured for about a century, and over this time, Rolex has proven itself able to create among the most reliable there are.

At the same time, over the years, Rolex has created numerous caliber innovations and improvements that have continued to improve Rolex’s reliability, precision, and high quality.

In fact, in the debate about calibers, there are many people who argue that Rolex watch movements are some of the best there is in terms of accuracy, reliability, and durability.

While Rolex has continued to make innovations with its movements, not much has changed when it comes to the way Rolex makes its calibers. Why change a winning concept, right? Rolex is all about small improvements. Rolex describes themselves as ”Pioneers in the development of the wristwatch, Rolex designs, develops, and produces in-house all the essential components of its watches, from the casting of the gold alloys to the machining, crafting, assembly, and finishing of the movement, case, dial, and bracelet.”

Each component in Rolex’s calibers has a purpose. They’re not designed to be the most visually appealing. They’re made to be the best in terms of function, reliability, and durability.

Furthermore, because Rolex calibers have proven to withstand the test of time, they continue to be extremely well-respected by watch connoisseurs and watchmakers alike and also continue to maintain great popularity and reputation on the vintage and secondhand Rolex market. While the Rolex calibers aren’t made with a focus on being visually beautiful, the pure art and beauty of a Rolex caliber lie within. While the Rolex calibers are rarely seen other by the Authorised and certified watchmakers, the Rolex calibers are complex pieces of mechanical engineering that have continued to improve and revolutionize the watchmaking industry many times over the course of Rolex’s history.

Because the caliber of a watch is the single most important part of a quality timepiece, it’s crucial to have good information about the calibers that Rolex manufactures and has made over the course of history. Unfortunately, though, the information available on the web is limited, and finding information about Rolex calibers can be a difficult task.

Therefore, we took it upon ourselves to create the most extensive, detailed, and thorough information list of Rolex calibers out there. In this article, we list all Rolex calibers of which it is possible to find information, and where possible, we’ve also shared more in-depth information about the caliber, such as power reserve and the number of jewels.

More information about Rolex calibers

Today, all Rolex calibers are made in-house by Rolex, and furthermore, Rolex is one of very few watchmakers that make all of the parts for its movements in-house. This goes to show the immense attention to detail that Rolex has, and the idea of never compromising.

Furthermore, all Rolex’s calibers have passed COSC tests which shows the high precision of Rolex calibers.

In the year 2000, Rolex created its first caliber which was entirely designed and manufactured in-house. This caliber was made exclusively for the Rolex Daytona Chronograph and it was the Rolex caliber 4130 movement. With the introduction of the 4140 movement, it came to replace the previous non-in-house movement of the Daytona which was a movement manufactured by Zenith. The first in-house movement completely made by Rolex was a caliber that featured fewer moving parts than any other modern chronograph, and at the same time, Rolex was able to achieve maximized accuracy and power reserve.

According to statistics by COSC, Rolex is the single largest mechanical movement manufacturer of chronometers.

The new 3000 Rolex caliber series

Rolex’s earliest version of the current in-house caliber is the 3035 movement system. This caliber was developed by Rolex and introduced in 1977.

This caliber is built upon the 1500 series and increased the balance speed, taking it from 19,800 BPH to 28,800 BPH.

The increase in BPH allowed a more accurate caliber. Rolex’s 3035 caliber was the first automatic self-winding watch mechanism that featured a quick-set function. This movement was used for Rolex’s men’s Date, Datejust, and, Submariner, and Sea-Dweller watch models.

The change and improvement of this movement allowed Rolex to create the smooth ticking ”sweeping hand” visual appearance that has now become an iconic trait of Rolex watches.

Rolex Oyster Calibers

Rolex uses perpetual calibers for its Oyster models, and these have come to become the most iconic calibers of Rolex. They are all self-winding mechanical movements, all tested by the Swiss Official Chronometer Testing Institute (COSC), making them certified as chronometers.

In creating their movements, Rolex pays an immense focus when it comes to creating calibers that have a high precision, high reliability, great shock resistance, efficient self-winding, and are easy to maintain.

These Rolex calibers are equipped with gold Microstella nuts and the large balance wheel that the calibers feature allows for high‑precision regulating and offers great stability.

On Rolex’s oyster calibers, you’ll find an outermost coil of the hairspring which is curled towards the center to counter the effects of gravity. What this does is create a caliber that has a great perfectly balanced and concentric isochronous oscillations assembly of the balance wheel-hairspring, contributing to improved chronometric precision, no matter the position of the watch.

According to Rolex, the caliber frequency of 28,800 beats per hour, which translates to 8 per second allows optimal conciliation of the oscillator’s precision and high reliability.

In the movement, there’s a traversing balance bridge, and this allows perfect and precise positioning of the oscillator, which improves the chronometric performance.

Furthermore, the rigidity of the bridge in the Oyster calibers creates a greater shock resistance.

Lubricants

When it comes to watchmaking, the quality of the lubricants used in the watches shouldn’t be compromised, and Rolex yet again proves that they compromise with nothing, not even their lubricants. In fact, in order to have proper functioning mechanical movements that work to perfection, Rolex has developed its own lubricants in‑house that have special characteristics which allow for longer life and improve the stability of the calibers over time.

Superlative chronometers

If you’re somewhat familiar with Rolex and their calibers, you’ve probably come across the term ”superlative chronometers”, but what does it really mean?

Well, the great feeling that comes with your watch when buying it is a symbol of Rolex’s status as a Superlative Chronometer.

This means that its calibers have passed rigorous tests. Not only have they been tested by COSC, but they’ve also undergone a series of final controls by Rolex themselves in their own laboratories according to a number of strict criteria.

This testing ensures the chronometric precision of the movement once inside the case,  its self-winding ability, and its power reserve, but also ensures the watch’s waterproofness.

Rolex’s Oscillator

The oscillator in a caliber is an important part, and Rolex calls it ”the guardian of time”.

The oscillator is composed of a hairspring and a balance wheel, and this allows for greater precision of the watch through the regularity of its oscillations.

After five years of research, Rolex introduced its patented blue Parachrom hairspring to its calibers. This oscillator is crafted from a paramagnetic alloy, and this makes it unaffected by magnetic fields, but also makes it up to 10 times more resistant to shocks than traditional hairsprings which are normally used in most other calibers from other manufacturers.

Rolex Paraflex

When talking about calibers and movements, it’s often spoken about rubies. These rubies can be found on the places in the movements that are subject to consistent friction, and of course (what did you expect?), Rolex has developed its own rubies known as parallax. In Rolex’s own words, the Paraflex is ”An exclusive and highly efficient shock absorber developed and patented by Rolex in 2005”.

This parallax has proven to improve the shock resistance of Rolex’s calibers by up to 50 percent.

”Superlative chronometer officially certified”

That’s the text that you find on the dial of every modern Rolex watch. But what does this sentence mean? The answer is that it refers to the beating heart of a Rolex watch – the caliber.

A watch could be called a chronometer by the manufacturer to prove its high precision. Of course, this was something that both risked and was subject to fraudulent abuse, but Rolex goes above and beyond to prove its movements approved chronometers. In fact, To guarantee the quality of Rolex’s chronometers, Rolex has made the choice to have all officially certified. This is even though it demands extra time and costs to get them to be just that.

In the 1930s, Rolex went from only inscribing ”Chronometer” to writing ”Officially Certified Chronometer”. Furthermore, in 1951,  the official certification became obligatory and came to cover all of Rolex’s watches.

Through its superlative chronometer officially certified seal of approval, Rolex wanted to differentiate itself, and it did so by obtaining certificates “avec mention” which was a certificate of superior performance when it comes to caliber performance.

At the end end of the 1950s, Rolex created a completely new, revolutionary generation of movements. These movements were up to three times more precise than what the criteria demanded to obtain a mention. To celebrate and prove its exceptional quality, reliability, and precision, Rolex created the “Superlative Chronometer”.

From thereon, this came to be added to the dials of all Rolex watches, eventually swapped to the now-used “Superlative Chronometer Officially Certified”.

Self-winding Rolex calibers

Today, all Rolex calibers are self-winding and automatic, and this is opposed to the previous mechanical wounded movements where the wearer constantly had to mechanically wind them to ensure that they could continue to work properly and maintain energy to operate. In 1931, Rolex invented the perpetual motion mechanism which consists of a half-moon-shaped oscillating weight rotating freely in both directions.

This oscillating weight allows the mainspring to be under continuous tension, which allows the watch to be provided with energy consistently. The wearer only has to wear the watch to ensure the watch continues running, as it is constantly ”charged/wounded”, and this also protects against over-winding.

What is a caliber?

By now, you’ve probably noticed that we use the term “caliber” then talking about the movements of watches. Fortunately, if you’re wondering what it means, it’s not very complicated. The term caliber, or caliber, is just another word for movement.

In a more technical context, you’ll see the word caliber being used, but in everyday use, you’ll often come across the term movement as they can be used interchangeably.
