Chronométrie Ferdinand Berthoud Precision Timepiece Brand Launches Chronomètre Fb 1l Series

Following the scientific spirit of the Enlightenment era, Chronométrie Ferdinand Berthoud precision timepiece brand launched a new innovative experimental timepiece series: Chronomètre FB 1L series, combined with the brand’s homemade uniform force cone wheel and sesame chain transmission tourbillon Movement and moon phase and moon phase display system never seen before.

  This series is launched in two styles, limited to 10 pieces each. One is an 18K white gold case with black ceramic lugs, and the other is a micro-blasted 18K white gold with a dark gray ceramic titanium case. This new series displays hours and minutes on the sub-dial at 12 o’clock, with a central second hand, and the back of the movement also displays a 53-hour power reserve. In the area at 6 o’clock, a large hand indicates the age and phase of the moon with a continuous back-and-forth operation mechanism; this complex function has not only become a patent-pending innovative design, but also combines the constant of the FB-T.FC.L movement. The power unit ensures the accuracy of the astronomical function of this series of timepieces. In other words, there is only one day’s error in 577 years of operation.

  Chronomètre FB 1L precision timepiece closely combines astronomical functions and precision timing functions and is certified by the Swiss Official Observatory (COSC) to commemorate Ferdinand Berthoud’s masters in timing accuracy and longitude calculation instruments. Great achievement. In order to achieve the goal of manufacturing precision measuring instruments, Master Ferdinand Berto created his famous nautical clock, which also became the source of design inspiration for the FB 1L series.

  Back related history

  It all started at 23Quai Conti in Paris. It has been home to the Royal Academy of Sciences (later changed to the Academy of Sciences) since 1666. Ferdinand Berto presented many sealed documents here in the 1850s. This is the early form of patent application. He applied for patent protection for many of his inventions.

  At the same time, here also, the French mathematician, physicist and navigator Jean-Charles de Borda presented his early research results as an engineer. Years later, he boarded several different ships back and forth to establish the calculation of longitude. To perform these tasks, he used measuring instruments made by Master Belto.

  These close collaborations between watchmakers, engineers, and navigators brewed the essence of the century in which Master Ferdinand Bertau was located-the master had completely experienced the famous scientific spirit of the Enlightenment. Collaborations similar to this are aimed at spreading knowledge and pursuing broader and deeper learning, and Master Belto has actively participated and contributed in both tasks. He contributed greatly to the Encyclopedia compiled by Diderot and D’Alembert. In this first comprehensive collection of theories, which aims to compile a comprehensive compilation of human knowledge, Master Bertu has written numerous articles related to watches and clocks. He has also authored many books on clock theory, and has written eleven books in thirty years!

  As a research scholar and watchmaker, Master Belto devoted his life to research and watchmaking. His countless research achievements in timing accuracy and longitude calculation have become the most authoritative reference model for decades. When the master was only 26 years old, he devoted most of his work energy to the research of instruments indispensable for precision measurement related to longitude calculation, such as a chronograph.

  Since 1752, the accuracy of the data measurement has been greatly improved, thanks to the improved instrument of Caval de Borda, which, therefore, is named after him and is called the ‘Borda Circle ‘(Also known as repeated measurement circle). This is an angle measuring instrument that measures the distance of an angle by repeating observations on a circle without returning to zero. Its characteristics are: the more the number of repeated measurements, the smaller the margin of error. To switch from an eighth circle (with an accuracy of 150 nautical miles, which is more than 270 kilometers) to a sextant (with an accuracy of 0.2 miles, or 370 meters), the de Borda ring is an indispensable instrument.

  The de Borda ring was designed to improve the reflection ring invented by Tobias Mayer in 1752. The German astronomer is famous for his ‘lunar maps’. These moon maps can accurately locate the moon, in fact, determine the longitude location.

  The Chronomètre FB 1L timepiece launched by Chronométrie Ferdinand Berthoud Precision Timepiece Company pays tribute to these pioneer pioneers. It is precisely because they know how to use their expertise to achieve more accurate timekeeping and astronomical measurement. To move forward.

  Brand new display system

  Chronomètre FB 1L precision timepiece is a model with moon age and moon phase display system. In other words, this model perfectly combines the precision chronograph function and astronomical measurement function. It cleverly combines two functions that have always been separated until now. However, almost three centuries ago, the combination of these two functions made the calculation of longitude more accurate and precise. This is also Ferdinand Bertua The main goals to be pursued by some research institutes.
  Moon age and phase are two different astronomical functions.
  The moon phase function is a more common complication in the watch industry. It shows the changes in the lack of the moon by various visual design methods on the dial. The phase change of the moon is cyclic, in four phases: the new moon, the first quarter moon, the full moon, and the second quarter cycle. If the period of the moon phase changes is used for calculation, from the new moon to the next new moon, it is a ‘new moon’. This complex function is not only symbolic, but also deeply aesthetic, but the moon phase function does not provide the accuracy required for astronomical use.
  Moon age days function can provide more accurate indicators. It calculates the exact number of days since the last new moon. This truly scientific measuring instrument, combined with precision timing measurements, was able to determine the longitude at sea with unparalleled accuracy nearly 270 years ago.
  For the first time in the FB 1L series, it is the first time on the same watch to combine two precision measurement functions, a precision timer, and moon age and moon phase display equipment.

  Constant power

  Chronomètre FB 1L precision timepiece is 100% self-made movement equipped with a very rare suspension cone wheel and sesame chain transmission power unit, which can constantly and equally transmit power to the escapement system throughout the movement of the movement, from The first rotation of the crown starts until it is fully wound, which enables the movement to have a power reserve of up to 53 hours.

  Drive the seconds tourbillon directly

  This movement is also equipped with a tourbillon that directly drives the second hand. The tourbillon can compensate for running errors caused by the watch being placed in different positions throughout the day, eliminating the errors caused by gravity to the clockwork. The driving wheel that connects the seconds wheel and the tourbillon frame has created a smart design that the tourbillon directly drives the seconds hand.

  Moon age days and new moons

  Most importantly, the FB-T.FC.L movement is loaded with the patentable complex function of ‘monthly age’ for the first time. This feature consists of two display designs. One is to display the age of the month in days, that is, a number from 1 to 14 is displayed in an arc area and is indicated by a pointer that moves back and forth. The number of days ‘1’ represents the first day since the new moon. The circle pattern facing the ‘1’ on the right side of the curved area symbolizes this new moon. The other three phases of the moon phase are also displayed one by one in the order of days In the same arc area. The circle pattern facing the 14th day symbolizes the full moon. When the pointer reaches this stage, it will gradually go back, that is, in the opposite direction, it will pass through different profit and loss circles every day until it returns to the circle facing the ‘1’ symbolizing the new moon.

  This day and month display is supplemented by a second display design, with a delicate hollow opening on the dial between 4 and 5 o’clock to show the phase of the moon at this moment-the profit or loss phase of the first or second quarter moon, In other words, the precise pointer indicating the age of the month is going up (to the 14th day) or going back (to the 1st day of the next new moon). This moon phase pointer is advancing at a speed that is imperceptible to the naked eye, but this precious moon phase display design at 4:30 can make it clear at a glance that we are moving towards the full moon or new moon.

  The bottom end of the pointer displayed by this moon phase is surrounded by a hemisphere at 4:30. On the two models of the FB1L series, this hemispherical design realistically reproduces the two main features that the moon can see or hide behind.

  The design of this ingenious mechanism was inspired by the successful time equation display system developed by Master Belto in 1752. The principle of this system is to use a sensing rod coupled with a time-equation cam, but the current design of this series uses a sensing device coupled to a moon-age cam.

  The invention of Master Beltou that year made him a master of watchmaking at the King’s Imperial Conference a year later. Today, this contemporary interpretation design can accurately display the age of the moon without a moon phase disk. This is thanks to a pointer that operates back and forth, following an accurate 29-day, 12-hour, 44-minute, and 15-second lunar cycle. In other words, after 577 years of continuous operation, there was only one day of error. The achievement of this remarkable result is thanks to the many gear design on the rotating disc at 4:30. As a result, Chronomètre FB 1L precision timepieces have far more accurate month-level functions than ordinary timepieces can only accurately display 122 years.

  The accuracy of each movement in this series is certified and has a certificate of precision timepieces issued by the Swiss official observatory certification (COSC) agency.
  Ferdinand Berthoud’s unique characteristic device has four patents, and now the FB 1L model’s unique moon age mechanism is also applying for two patents.


  The design of the trimmed case is inspired by the structure of the marine precision chronograph created by Master Ferdinand Berto since 1760. He draws inspiration from the marine clocks he made, especially the universal axis design of the marine clocks, which can ensure that the dial of the marine clocks always maintains a stable horizontal direction during sailing.
  For the first time, the case of the FB 1L series is equipped with a selector button set at 4:30, which can be selected between the two positions of L and H to adjust the moon age or time.


  Chronomètre FB 1L precision timepieces are available in two styles.
  The FB 1L.1 style ‘Near Sideofthe Moon’ focuses on showing a warm and bright style, evoking the visible side of the moon and the strong moonlight of the full moon. This model comes with a polished 18K white gold case middle, side edge components and crown, with black ceramic lugs.
  The FB 1L.4 style ‘Far Sideofthe Moon’ reflects the far side of the moon, hidden behind it, showing a darker and mysterious tone. The middle case of this platinum case is sandblasted on this model, and the lugs and side edge components are replaced by a dark gray ceramic titanium gold material instead of another black ceramic design. This type of ceramic titanium is on average four times harder than ordinary titanium. This is fully in line with Ferdinand Berthoud’s philosophy of pursuing ruggedness, which has previously driven watchmakers to develop carburized steel with similar robust characteristics.
  The above two styles are numbered and limited to 10 pieces.
