1926 Oyster case
The original Oyster case was 36 mm in diameter, and its sealed case was its most prominent feature. This was due to Rolex’s original patented system, which consisted of a screw-in outer ring bottom cover and a winding crown. The triangular grooved bottom cover is screwed and sealed with special tools. Only professional tools can open and access the movement. The waterproof Oyster case can provide good protection for movement, protecting it from water, dust pressure, and impact damage.
1931 Perpetual Oscillating Weight
The Rolex Perpetual Oscillating Weight includes a half-moon-shaped automatic rotor that naturally swings in two directions around the central axis as the wearer’s wrist moves. The rotor transmits energy to the watch’s mainspring. The advantage of the perpetual automatic rotor is that it does not need to be wound every day, which helps enhance the Oyster model’s waterproof performance. People do not need to unscrew the crown regularly to avoid exposing the movement to dust and moisture. The automatic rotor continuously winds the mainspring, providing a continuous and stable power source for the watch, making the watch more accurate.
1953 double-lock crown
The double locking mechanism ensures the screw-down crown is entirely waterproof, thanks to two sealing areas in the tube and crown. When the Submariner was first launched in 1953, it used a double-buckle winding crown. This was a milestone for Rolex’s first watch to be waterproof to a depth of 100 meters. Even if the crown is not fully tightened, the waterproof performance of the case can still be maintained. The double-lock waterproof Rolex crown will have two dots under the crown logo if it is a precious metal and a horizontal bar if it is a 904L steel model.
2000 Parachrom hairspring (blue niobium hairspring)
The Parachrom hairspring is made of niobium, zirconium, and oxygen alloy. Although this crucial component is less than one centimeter in diameter, it ensures the watch’s accuracy with its excellent performance. In 2005, Rolex adopted a new patented technology to improve the surface of the Parachrom hairspring to ensure its long-term stability further. This treatment also gave the hairspring its signature blue luster. Replica watches for sale.
2005 Paraflex suspension
The balance wheel is the mechanical heart of the watch. It is constantly active and has strong inertia, maintaining the watch’s timekeeping performance. When a watch is hit, the balance shaft is the most vulnerable part of the movement. To minimize friction, the smaller the balance axis, the better. Usually, its diameter is about 0.07 mm, which is as thin as a hair, so it is very fragile. Rolex has developed a more efficient shock absorber to ensure the precision travel performance of the balance wheel while increasing shock resistance by 50%. The spring, a vital part of the shock absorber system, has been redesigned, and the brand used computer simulation to completely change the original geometric structure of the spring, allowing the shock absorber to withstand more substantial impacts.

2005 Cerachrom bezel
Used in some Oyster series professional watches, the Cerachrom bezel is made of ceramic. This unique ceramic is hard enough, not easily scratched, and will not fade even when exposed to ultraviolet rays. In addition, its polishing effect is good, giving the outer ring an outstanding and lasting luster. The ceramic outer ring is engraved with numbers and scale marks to facilitate time identification. It is coated with a thin layer of gold or platinum using physical vapor deposition technology (PVD). As long as the Cerachrom ceramic word ring is used, it must be a hot-selling style of Rolex watches.
2014 Syloxi Silicon Hairspring
Syloxi silicon hairspring has obtained a total of five patents, and together with Parachrom hairspring, it is Rolex’s high-performance hairspring. Syloxi silicon hairspring is not disturbed by magnetic fields, and its performance is stable even if the temperature changes. Syloxi silicon hairspring can be ten times more accurate than traditional hairsprings, including optimizing the geometric structure of the hairspring and designing the fixing system to be more effective, making it helpful in improving watch performance.
2015 chronology escapement
Watchmakers favor the stable and reliable Swiss lever escapement system, but its weakness is its low efficiency. Only slightly more than one-third of the power transmitted to the mainspring through the gear set can be transmitted to the balance wheel. The geometry of the Chronergy escapement increases this main component’s efficiency by 15%. Nearly half of the new power reserve of the 3235 and 3255 movements comes from the escapement. The Chronergy escapement is made of nickel-phosphorus. The advantages are also Not affected by magnetic fields.
2015 Oysterflex Rubber Strap
The inner layer of the Oysterflex rubber strap has a patented longitudinal buffering system, such as a stretchable rubber sheet. The interior is made of elastic nickel-nickel alloy sheets. The front and rear ends are connected to the case and Oyster safety buckle, respectively, and then black rubber is Covered and formed; its sturdiness is beyond most rubber watch straps. Even if it is pulled by muscular force, the watch will still be worn safely on the wrist. It can be equipped with Oyster safety clasps of different materials to prevent the strap from being accidentally released. It is also equipped with Rolex’s patented Easylink quick extension system, which can increase the length of the strap by about 5 mm.
