The provided manual describes the Rolex Oyster Perpetual Milgauss watch, a sophisticated timepiece designed for precision and resistance in challenging environments. This watch is a testament to Rolex's commitment to technological and scientific progress, expertly blending robust engineering with chronometric accuracy.
The Rolex Oyster Perpetual Milgauss is a self-winding mechanical watch that displays hours, minutes, and seconds. Its primary function is to provide accurate timekeeping, even when exposed to strong magnetic fields. This capability is particularly beneficial for engineers and technicians whose work environments often involve magnetic interference that can disrupt the performance of conventional mechanical watches. The Milgauss was specifically engineered to resist magnetic fields of up to 1,000 gauss, a feature that gives the watch its distinctive name ("mil" for a thousand).
The watch is equipped with a self-winding mechanical movement, entirely manufactured by Rolex, ensuring its reliability and precision. The Oyster case, a hallmark of Rolex watches, provides exceptional robustness and waterproofness. The Milgauss model features a 40 mm Oyster case, guaranteed waterproof to a depth of 100 meters (330 feet). This makes the watch suitable for various activities, including swimming and snorkeling, though it should not be used for deep-sea diving.
A distinctive aesthetic feature of the Milgauss is its orange seconds hand, which is shaped like a lightning bolt. This design element is a nod to the original Milgauss model and underscores its resistance to electromagnetic interference. The dial is designed for exceptional legibility, featuring Chromalight hour markers and hands. These elements are filled with a luminescent material that emits a long-lasting blue glow in darkness, ensuring the time can be read clearly in low-light conditions. The watch's sapphire crystal is virtually scratchproof, further enhancing its durability and maintaining its pristine appearance over time.
Before wearing the Rolex Oyster Perpetual Milgauss for the first time, or if it has stopped, the watch must be manually wound. To do this, the Twinlock winding crown, which features a double waterproofness system, needs to be unscrewed completely from the case. Once unscrewed (position 1), the crown should be turned clockwise a minimum of 25 times to provide adequate partial winding. Turning the crown in the opposite direction will have no effect on winding. After manual winding, the watch will continue to be wound automatically as long as it is worn on the wrist, thanks to its self-winding mechanism.
To set the time, the crown is unscrewed and then pulled out to the first notch (position 2). In this position, the seconds hand stops, allowing for precise time setting to the exact second. The hour and minute hands can then be adjusted by turning the crown in either direction. After setting the time or winding the watch, it is crucial to carefully screw the crown back down against the case. This action ensures the watch's waterproofness and protects its internal mechanisms from dust and moisture. The crown should never be unscrewed underwater.
The watch also features an Oyster bracelet with an Oysterclasp and the Easylink comfort extension link. The Easylink system is a patented design that allows the wearer to adjust the length of the bracelet by approximately 5 mm without the need for any tools. This feature ensures optimal comfort in various circumstances, accommodating changes in wrist size due to temperature or activity. Adjusting the Easylink from the short to the long position involves pulling the link outwards until it clicks into place. Conversely, adjusting from the long to the short position requires pushing the link inwards until it clicks.
The Rolex Oyster Perpetual Milgauss is designed for durability and requires minimal day-to-day care, thanks to Rolex's expertise and high-quality manufacturing. To preserve its luster, the watch should be cleaned occasionally with a microfiber cloth. For a more thorough cleaning, the case and bracelet can be washed from time to time using soapy water and a soft brush. It is particularly important to rinse the watch with fresh water after wearing it in the sea to remove any salt and sand deposits, which can otherwise cause damage or corrosion. Before any cleaning, it is essential to ensure that the crown is properly screwed down against the case to maintain its waterproofness.
For long-term accuracy and waterproofness, Rolex recommends periodic professional servicing. The timekeeping accuracy of the watch relies on high-performance lubricants specially developed by Rolex to minimize friction and prevent wear of components. When a Rolex watch is serviced by an Official Rolex Jeweler or Service Center, it undergoes a comprehensive process. The watch is completely dismantled, and all its components are cleaned. Each individual component is closely examined, and any parts that no longer meet Rolex's functional and aesthetic specifications are replaced with genuine Rolex parts.
The movement is carefully lubricated, and its timing accuracy is rigorously tested. The case and metal bracelet are meticulously refinished to restore their original luster. After a complete Rolex service, the watch undergoes a series of rigorous technical tests and checks to guarantee its waterproofness, power reserve, and precision. A complete Rolex service is covered by a service warranty, providing peace of mind to the owner.
Rolex maintains a worldwide service network of Official Rolex Jewelers and Service Centers in over 100 countries. These centers are staffed by highly skilled watchmakers, carefully selected and trained by Rolex, who can provide advice on all technical aspects of the watch's functions, including bracelet sizing and complete servicing needs.
