Datograph “Dufour graph”
Announced in 1999, it shocked the watch industry at the time of the year 2000 problem at the end of the century.
The Datograph is the world's first chronograph that features a flyback, precision jumping minute counter, outsize date, and stop-seconds functions.
Even today, it is said to be the "highest value" chronograph.
Development began in 1994, the year after the company achieved reconstruction in 1995 in collaboration with Günter Blümlein.
It took four years to complete, and about a quarter of a century has passed since it was finally announced, but it still boasts a level of perfection that has not lost its luster.
Throughout the history of mechanical watches, the versatility and influence of chronograph mechanisms lies in the sheer technological prowess of each company.
The technical point in particular lies in the control ability. In the chronograph mechanism, which is a measuring mechanism, the basic operation of the series of operations of start, stop, and reset is structurally
Because it requires strong torque from the mainspring, the chronograph second hand may sometimes become misaligned or blur.
In addition, it was common knowledge in the manufacturing of chronograph mechanisms that this would affect the timekeeping accuracy of the main hour, minute, and second hands.
In addition to the basic operations of start, stop, and reset, this Datograph has a flyback function that prevents any "shift" or "shake" from occurring.
Even though it is equipped with a stop second, it does not affect timekeeping accuracy, and it is a mechanism that boasts a high level of perfection that does not affect the company's traditional torque loss when switching to an outsize date.
The control mechanism of this perfect movement is a classic column wheel type with 18000 vibrations, and the heart is unique in that it operates slowly and powerfully.
In addition, the beautiful layout of Cal.L405, which consists of 951.1 parts, is one of the reasons why master craftsman Philippe Dufour uses this rare chronograph.
I once asked a senior member of the company's German headquarters a question. What are the strengths of this Datograph?
The answer is, ``High functionality and high precision are the obvious basic elements in Datograph development, and what we focused most on was how to create a beautiful design layout.''
I realized that this idea probably applies to all Lange products, and at the same time, I remember being keenly aware that it contained all of the company's unwavering beliefs and philosophy.
