First, we need to know that the essential point is that Rolex launched a chronograph watch as early as the 1920s. Di Tong has just been pushed to the market as a sports car timing series. Later The originator of Rolex hopes that everyone will understand.
Categorize Di Tong for a simple time. From the three key time nodes, the historical context is more explicit:
1963 72 fingerprint movement, 1988 4030 automatic movements, 2000 4130 self-produced movement
First, Rolex designed a time racing discount replica watch with the Daytona logo to commemorate the Dtonga track. Currently, Rolex still chose a reliable Valjoux 72 manual chord timing movement. For the few options, many brands have also been adopted. Manual stringing, the movement design is reasonable and stable; Rolex has also changed the movement’s movement, re-polished, replaced the higher-level screws and fine-tuning wheels, double-layer blue steel travelers, and canceled the fast-slow needle structure.
So why has this manual movement been replaced for so many years? It is also well-speculated in combination with history. First, the research, development, and production cost of timing movement is relatively high. For Rolex, the timing wrist The table undoubtedly chooses the general direction.
Later, the automatic timing movement was launched in 1969. Rolex felt that the mechanical timing of the action was becoming increasingly important. Still, when it encountered a quartz storm, the sales of its best replica watches became a problem, and it did not consider designing the self-produced timing movement. Until the end of the 1980s, the clocks resumed vitality. Still, Rolex was very embarrassed to find that it was difficult for its production line to support the self-produced timing movement, so they put the target into the real-time moving of the real power that resumed production then.
During the 1988 Basel Watch Exhibition, Di Tong, who launched the real-time moving, was also the first time to board the chain watch automatically. In 1986, Rolex began to improve El Primero’s time movement. Rolex launched up to 200 improvements on the El Primero movement.
In addition to the changes in materials and polishing, the more critical changes: Rolex reduced El Primero’s swing from 36,000 to 28800, reaching 52 hours of power and 31 gem bearing; removed El Primero’s calendar device; El Primero’s original flat game was changed to the Breguet -style tail. After the improved El Primero movement, it was named CAL.4030 fully automatic timing movement by Rolex.
There is another problem in purchasing movements from Zhenli. Lemania founded some parts of the timing movement at that time. In the 1990s, Lemania was sold to Breguet due to poor management, so the direction of the action when Zhenli was in the absolute power generated variables. , Rolex is also determined to develop automatic timing movements independently.
In 2000, Rolex finally came up with CAL.4130, a self-produced timing movement, and appeared at the table exhibition, drew several long-distance lengths, and designed the best time movement in the industry so far. There are four aspects of its core advantages.
Pearl bearing and high -efficiency upper -chain device
Guide column wheel and vertical timing clutch device
Large balancing wheel configuration fine-tuning screw
Subsequently, the improved clutch was equipped with a unique occlusion design of MEMS technology manufacturing. These five points pushed Di Tong’s throne to the peak, and they finally got the title of the large factory that can be counted as large factory.
The three timing of Rolex has strong characteristics of the times. The Ditonga series also witnessed the process of Rolex’s transformation. Walking step by step from childhood to the giant to completely independent design self-production aligns with Rolex’s consistent calmness. Careful style.
