At the 60th anniversary of the Rolex Cosmic Sterites Di Tonga series launch. At this critical time in every ten, its upgrade and revision have naturally become the topic of cousins. This time, the new Dicong of the release was redesigned with several details, and the back of the back was added for the first time. The new CAL. 4131 movement with this work is also worthy of attention. (Watch model: 126506)
The first-generation Di Cosmos was available in 1963. It is positioned as a professional racing chronograph. It is characterized by the speed measuring meter outer ring. It can read the average rate of a certain distance within a fixed time. In 1965, the Di Tonga series evolved further, replacing the original pump pressure button with the rotation timing button, which allowed the controller to avoid being accidentally pressed. Di Tong has achieved a legend in the racing world with its reliable and outstanding performance. Sixty years after the series launch, the series still took the lead in the exercise.
The new “Ice Blue Di” uses a 950 platinum border ceramic bezel to enhance the luxurious texture of the bezel. In the case of constant diameter, the newly added platinum bonding makes the ceramic bezel more slender. The integrated formation of pottery outer and pottery rings developed by Rolex’s development is not only anti-scraper but also not vulnerable to environmental impact. This high-tech ceramic ring is made of special chemicals and is extremely difficult to erode.
The 40 mm oyster case is cast with 950 platinum, and the crown and shoulders are optimized. The new Datong’s chronograph small disk scale is also optimized, which is more delicate and thin.
The waterproof depth of the watch is 100 meters (330 feet). The brand uses exclusive special tools to tighten the fine pits’ bottom cover to seal the case. The three-buckle-linked chain crown has a triple waterproof system. Like the timing button, it is firmly tightened to the point. The crown shoulders are integrated with the middle case to protect the upper linked list crown and give the movement the best protection.
The new cosmic gauge Tongtong has many styles to choose from. Among them is the “ceiling” ice-blue series with an oyster strap, which is highly recognizable. The three-square-chain oyster straps launched in the late 1930s, sturdy and reliable, are the most strap with the oyster constant-moving series best replica watch site.
The Rolex triple-chain oyster strap is solid and reliable. It is the one with the most oyster constant mobile series replica watches. The cosmos-type Dutonga’s oyster strap has folding oyster insurance to buckle and prevent accidental opening. Oyster straps are installed with the easy-to-adjust chain extension system developed by Rolex, and the wearer can easily extend the strap by about 5 mm.
Back is a big highlight of Xinshita, the first time the Rolex professional (sports model) has adopted this design. The rotating bottom cover is made of 950 platinum with the same case, embedded in an anti-reflective blue crystal mirror, and its edges have fine pits.
The watch is equipped with the Rolex 4131 movement that debuted for the first time. The structure of the movement has been dramatically innovated, and the number of streamlined components makes it more reliable. The 4131 campaign uses the Rolex patented Chronergy escapement system. Auto Tuo is equipped with improved pearl bearing. The 4131 movement uses the constant mobile automatic chain system. With the efficient coordination of the structure of the clockwork box and the escapement system, the dynamic reserves can reach 72 hours.
The 4131 movements are equipped with a solid column wheel and vertical timing clutch device, which can instantly start the timer to ensure accurate timing. The plywood of the 4131 movements is the Rolex Nikko -Genova wave pattern. The micro-grinding light pits are decorated between adjacent decorative patterns to interpret the unique design different from the traditional Geneva wave pattern.
In addition, the movement is also equipped with blue Parachrom. This kind of traveler is made of unique custody alloys. Even if the temperature changes, its physical characteristics are still very stable. The trace is also equipped with the Rolex Merchant Circle to ensure the movement can still be operated anywhere. Wanderer components are provided with high-performance Paraflex cushioning devices designed and patented by Rolex to improve the seismic resistance of the action.
Like all Rolex watches, the Oyster Hengdi Cosmic Type Di Tonga was also certified by Rolex in 2015. In addition, the 4131 movements have been approved by the Swiss official precision timepiece test center (COSC) simultaneously.

Its accuracy is much higher than the standard of the precision timepiece of the Swiss official Observatory.
