The Chronograph Chronometer from the only manufacturer of Swiss watches in Germany presents itself with a new heart and a new face.
The heart: the Chronograph Chronometer, which has been in successful series production for many years, has now, due to popular demand, been equipped with a date display. Some time ago, the Caliber C.741 was modified for Chronoswiss by changing the conventional window date to the hand-display date.
What makes this model tick in the current series is the mechanic chronograph calibre C.741 C with automatic winding mechanism that already made a name for itself in the Chronoswiss Klassik chronographs.
25 functional jewels combine with 1/4 second timekeeping precision, 30-minute and 12-hour hands to form an expression of top-quality watch-making craftsmanship. Now, the face exudes the aesthetic clarity that Gerd-R. Lang strives for with his mechanical treasures.
The face: the new date display at the “3” not only provides the wearer with an important piece of additional information, it also lends perfect symmetry to the fine guillochet face.
Also displayed on the solid silver face is the number of your personal certificate of accuracy, which each new owner receives upon purchasing this model.
The founder and owner of Chronoswiss, Gerd-R. Lang, proved very early on in the development of his watches that having numerous additional functions does not have to have a negative effect on the precision of a mechanical wristwatch. In addition to the popular chronograph function, this attractive model also has true chronometer quality.
It is a great distinction for a mechanical watch when it can call itself a chronometer. This honour can also be bestowed on a chronograph.
A chronograph is timepiece with two movements that work independently of one another. One displays the current time, while the other, which has a stopwatch function, makes the measurement of another time possible. This additional time measurement is displayed with separate second, minute and hour hands, which are started, stopped and reset using a push-piece.
A chronometer is a top-quality mechanical timepiece which has to be subjected to a precision test known as the “Bulletin de Marche”. This test is carried out in an independent and official Swiss watch and clock institute, and to pass it, deviations in the watch movement have to remain within strict predetermined tolerance levels throughout a period of 14 days.
For a chronograph with two independent movements, as is typical for this kind of timepiece, both movements must pass a test program that is 6 full days longer than the usual test in order to be awarded the prized “Bulletin de Marche”. And the chronograph hand must also start and stop without any irregularities or delays.
The face of the Chronograph Chronometer continues to be available in either solid silver or elegant black.
