From designing a new model to individually testing each watch in production, every effort is made to ensure that all of the brand’s outstanding standards of excellence are met. Rolex played a pioneering role in the development of tests and protocols to ensure the robust reliability and durability of their watches.

For shocks or impacts, or changes in temperature, magnetic fields, wear and tear, humidity – Rolex watches must be able to withstand even the harshest conditions for a long time without breaking down. affect their integrity or performance. For Hans Wilsdorf, the brand’s founder, it is essential to every Rolex watch to ensure accurate time and to protect the movement in the best possible way. Over a hundred years since the launch of the first models, this philosophy has always been underpinned by the development and production of each watch bearing the brand’s iconic crown crown.

Ensuring the reliability of each Rolex watch requires the brand to apply a wealth of skills and a wide range of expertise. Engineers specializing in materials, physics, mechanics and microtechnology, as well as technicians, movement engineers, prototype builders, statisticians and astrologers work together to develop the best solution for each product model, depending on the intended use.

From original prototype to complete watch

The process begins at the new product design stage. A list of extreme conditions is drawn up for testing the watch. Creating a virtual and process-based scenario is the first step in outlining the risks and, in turn, prioritizing the obstacles for the initial approach. From there the simulation was programmed to operate. All of it is used to design the first prototypes, as well as a series of tests that simulate actual wearing conditions.

A watch is developed in three stages: prototype validation, prototype functional development and prototype overall development. Several test prototypes will be created, analyzed and tested separately. Once the prototype validation phase is verified, the prototype functional development will continue to refine the functionality of the mechanical movement. The pre-production phase then begins with the production of development prototypes. Finally, upon completion of this phase, mass production can begin.

Launch of the Super Chronometer certification. In order to obtain this designation, all finished watches must undergo a series of fully automatic tests after leaving the factory. This high-tech control chain, exclusive to the brand, guarantees the accuracy of the watch to within -2/+2 seconds per day – a tolerance unique to Rolex. This standard is far more precise than that required by the COSC (Official Swiss Chronometer Testing Institute). It also ensures that the automatic winding of the watch is consistent with the stated power reserve, that the watch is water resistant to the required depth, and that the automatic winding module is functioning properly. If the watch successfully passes this series of tests, it is certified by the Super Chronometer and is awarded the Green Seal, along with a five-year warranty. This step outlines the entire process of ensuring the reliability of the watch.

The battery in the code test

Among the many tests carried out to confirm the reliability of Rolex watches, resistance to shocks and drops are the main areas of study. Impacts rated as “everyday” shocks occur when the watch is subjected to wear and tear from everyday activities, such as hand clapping. In addition, “abnormal” impact tests reproduce the effect of a watch when dropped under random conditions or from a defined angle. This rapid, sudden acceleration can reach a maximum acceleration of 5,000g.

Life tests are performed on the case and strap as well as on the movement. For example, the dial’s resistance to UV light is evaluated to ensure that the color remains stable over time. Robots are used to measure the progress of wear on metal straps at the joints between components, such as between the case and the strap, or between joints. This process replicates and accelerates the typical movements of a Rolex watch wearer, under conditions of air pollution and abrasive resonance, accelerating the damage to the product.

For the movement, the brand pays more attention. The chronograph performance, the power reserve and the power of the self-winding module in the movement are systematically tested, as well as for functionality and service endurance. All the mechanical systems that make up the movement are tested on a device capable of replicating the action of setting and adjusting the watch under real-world conditions.

In order to fully complete the process of ensuring the reliability of the watch, aesthetic and ergonomic requirements need to be taken into account. Since the design of the model could not be changed during the development process to overcome technical issues, ingenuity was key in coming up with a solution considering the many variables involved. Comfort is also key, as users will feel comfortable with a watch that is both easy to use and comfortable to wear. Weight, texture and feel on the wrist, as well as accuracy and ease of function, are important factors that influence the design and manufacture of a Rolex watch.
