These small yet mighty screws are essential for adjusting the balance of the movement and ensuring accurate timekeeping. But the question remains, do all vintage Rolex models with the 1520 movement have micro stella screws? To answer this question and dive deeper into the technical details of Rolex movements, we will explore the fascinating history of micro stella screws and their significance in vintage Rolex watches.

Whether you are a seasoned collector or just beginning your journey in the world of vintage Rolex, this article will provide valuable insights into these intricate timepieces.

Fining Tuning the Balance of a Luxury Watch is Important

Fine-tuning the balance of a luxury watch is important because it affects the accuracy and precision of the watch’s timekeeping. The balance wheel and hairspring are critical components of a mechanical watch movement that regulate the movement of the watch’s hands. The balance wheel oscillates back and forth at a specific rate, which is determined by the length and thickness of the hairspring. If the balance wheel is not properly balanced, or if the hairspring is not adjusted correctly, the watch may lose or gain time, which can be frustrating for the owner.

Luxury watch brands invest significant resources into developing and fine-tuning their watch movements to achieve optimal accuracy and precision. Fine-tuning involves adjusting the balance wheel and hairspring to ensure that the watch keeps time within a certain range of accuracy, usually measured in seconds per day. By fine-tuning the balance of their watches, luxury watch brands can offer their customers timepieces that are reliable, consistent, and perform at the highest level of precision.

Micro Stella Screws - Rolex

The History of the Micro Stella Screws in Luxury Watches

Rolex was founded in 1905 by Hans Wilsdorf and his brother-in-law Alfred Davis in London, England. Originally, the company was called “Wilsdorf and Davis,” and it imported Swiss movements and assembled them into high-quality watches that were sold to jewelers who put their own brand names on them.

In 1908, Wilsdorf registered the trademark “Rolex,” and the company began producing its own movements. The name “Rolex” was chosen because it was short, easy to remember, and could be pronounced in any language.

Over the years, Rolex became known for its innovation and quality, and the brand quickly became popular with adventurers and explorers who relied on the watches’ accuracy and durability. In 1926, Rolex introduced the first waterproof wristwatch, the Oyster, and in 1931, it introduced the first self-winding mechanism, which it called the “Perpetual” movement.

Throughout the 20th century, Rolex continued to innovate and develop new technologies, including the micro stella screws.

Micro stella screws are a proprietary invention of Rolex and are used exclusively in their watch movements found in some of the earliest watches. They are not used in other luxury watch brands or models. The precision and accuracy achieved by Rolex through the use of micro stella screws are a hallmark of their watchmaking excellence and set them apart from other luxury watchmakers. While other high-end watch brands use different techniques to achieve accuracy and precision, micro stella screws remain a unique and defining characteristic of Rolex watches.

The Rolex 1520 movement made its debut in the early 1960s and remained in production until the late 1970s, marking a significant era for the watchmaking industry. The Micro Stella screws replaced the traditional system of using a swan-neck regulator to adjust the balance, and allowed for more precise adjustments to be made to the balance of the movement.

Interestingly, the incorporation of micro stella screws in Rolex movements became more prevalent during this time, resulting in enhanced precision and accuracy. However, the presence of micro stella screws in a vintage Rolex watch with the 1520 movement depends on the model and the year it was produced, adding to the watch’s uniqueness and historical significance.

The Rolex micro stella screws were invented and used to adjust the balance of the watch movement, which is a critical component that regulates the watch’s accuracy. These tiny screws allowed for finer adjustments to be made to the balance, resulting in greater precision and accuracy. Additionally, the use of micro stella screws simplified the process of adjusting the balance, making it more efficient and effective. Rolex’s commitment to innovation and precision in watchmaking led to the development and widespread use of micro stella screws, solidifying its reputation as a leader in the industry.

The micro stella screws played an important role in aiding Rolex as an official timekeeper. The screws allowed for precise regulation of the watch’s balance, which is essential for accurate timekeeping. The balance is the component in a watch that oscillates back and forth and controls the rate at which the watch keeps time.

By using the micro stella screws, Rolex could fine-tune the balance of its watches to ensure that they were running as accurately as possible. This was particularly important for competitions that required precise timekeeping, such as racing and diving events. The accuracy of Rolex’s watches, which was helped by the use of the micro stella screws, made it a natural choice for official timekeeping duties at many such events.

Rolex’s reputation for accuracy and as a leader in the industry, was instrumental in its success as a timekeeper in many competitions. In order to be an official timekeeper, a watch brand must have a proven track record of accuracy and reliability. Rolex’s focus on precision and innovation in its movements helped it establish this reputation. For example, in the 1950s, Rolex introduced the “Chronometer” certification for its watches, which was an independent rating system that tested the accuracy of the watch in various conditions.

Many competitions, such as racing and diving events, require precise timekeeping to determine winners and track records, and Rolex’s reputation for accuracy and reliability made it a natural choice for these events. Additionally, Rolex’s involvement in sponsoring and timing such events further reinforced its brand image as a high-end, luxury timepiece that could be relied upon for precision and accuracy.

Do All Vintage Rolex Watches Have Micro Stella Screws?

Most vintage Rolex watches that were produced with the Calibre 1520 movement or its variations are likely to have the Micro Stella screws. However, not all Rolex watches with the 1520 movement have Micro Stella screws, as they were only gradually introduced into Rolex movements from the late 1960s onwards. Some of the Rolex models that are known to have the Micro Stella screws include the Datejust, Day-Date, and Submariner models produced in the 1970s and onwards.

It’s important to note not all vintage Rolex watches after 1960 have the micro stella screws. The use of micro stella screws in Rolex movements became more common in the late 1960s, which means that if you have a vintage Rolex model from the early 1960s or earlier that uses the 1520 movement, it is more likely to have a balance with a regulator that uses screws, but not micro stella screws. The use of micro stella screws gradually increased over time, so the presence of these screws in vintage Rolex watches depends on the specific model and the year it was produced.

By 1960, the watches produced that uses the 1520 movement, it is more likely to have micro stella screws. By this time, the use of micro stella screws had become more widespread in Rolex movements, and the screws were gradually phased into use over time.

Patek Phillippe Luxury Watch

Do Other Pre Owned luxury watches Like Patek Philippe and Omega Watches Use Similar Balancing Features like Rolex’s Micro Stella Screws?

Patek Philippe watches use a proprietary system called Gyromax to adjust the balance of their watch movements. While it is not the same as the micro stella screws used in Rolex watches, Gyromax is also a highly precise and accurate system that allows for fine adjustments to the balance of the movement.

The Gyromax system uses small weights that are attached to the rim of the balance wheel to adjust its inertia, which affects the watch’s accuracy. Patek Philippe’s use of the Gyromax system is an example of their commitment to innovation and precision in watchmaking, similar to Rolex’s use of micro stella screws.

Patek Philippe introduced the Gyromax balance system in the 1949 reference 2555 model, which featured the Calibre 12-600AT movement. The Gyromax system was a significant advancement in watchmaking technology and allowed for precise adjustments to the balance of the movement. Since then, Patek Philippe has continued to refine and innovate their balance system, and it remains a hallmark of their commitment to precision and accuracy in watchmaking.

Omega has a similar feature called the “Micro Adjustment” system, which allows for precise regulation of the watch’s balance. Similarly, Patek Philippe has the “Gyromax” system, which also uses small screws to fine-tune the balance of the watch. These systems are all designed to improve the accuracy of the watch and ensure that it keeps precise time.

What Are the Fifty Fathoms and How is this Significant to Rolex Watch Collections?

The Fifty Fathoms is a diving watch that was created and first introduced by the Swiss watch brand Blancpain in 1953. It was one of the first purpose-built diving watches, designed for use by professional divers, and set the standard for dive watch design that still exists today. The Fifty Fathoms featured a rotating bezel for measuring elapsed time, luminous markers for improved visibility in low light conditions, and a water-resistant case.

The Fifty Fathoms was significant to Rolex watch collections because it inspired the development of the brand the Rolex Submariner, which was introduced a year later in 1954. The Submariner featured many of the same design elements as the Fifty Fathoms, including the rotating bezel and luminous markers, but also included Rolex’s own innovations, such as their patented Oyster case and the use of the micro stella screws we discussed earlier. The Submariner became an icon in its own right and helped cement Rolex’s reputation as a leading manufacturer of high-quality and durable diving watches.

Idaho Pawn & Gold

Recently, at Idaho Pawn and Gold in Meridian, we had a client bring in a vintage Rolex Submariner from the 1960s. The watch featured the 1520 movement, and the client was concerned that it might be a fake. The client had been told by another dealer that the watch was not authentic, but our watch expert was able to determine its authenticity by pointing out a technical difference based on the year.

As we mentioned earlier, the use of micro stella screws in Rolex movements did not become common until the late 1960s. Therefore, a vintage Rolex model with the 1520 movement from the early 1960s or earlier is more likely to have a balance with a regulator that uses screws, but not micro stella screws.

In the case of our client’s Rolex Submariner, our watch expert identified the screws in the balance regulator, confirming the watch was indeed authentic. The client was thrilled to have the watch validated and grateful for our expertise.
