Rolex Tru-beat Jump Second Watch

Many of today’s big names have also appeared in the seconds jumping work: Rolex equipped with the Tru-Beat movement 1040, Audemars Piguet launched the Millennium series jumping seconds watch equipped with the movement 2905 in 2007, Omega Synchro-Beat introduced in the 1950s, Minute Decimale with 100 beats per minute introduced by Longines, Independent PAM00080 with Panerai equipped with Chezard movement, and Dancing watch with Chezard 7400 movement by Doxa.
Many people have such a prejudice that when they see a watch in the form of ‘One Second A Hop’, they call it ‘Quartz Watch’. This can be seen as the profound impact of the ‘Quartz Crisis’ of the 1960s and 1970s, or it can be considered a lack of understanding of the history of watches and clocks. In fact, the ‘second hop’ display is not the original of the ‘quartz watch’. Before the quartz technology appeared in the 1970s, the field of mechanical watchmaking had long been called ‘step’. Progressive structure of the progressive second hand. According to historical records, the earliest produced in 1850 left & mdash; & mdash; reveal the mechanical jump seconds display right pocket watch, has already found the figure of the jump seconds movement. Subsequently, this unique way of moving the second hand entered the ‘big eight’ pocket watch in the Chinese market in Switzerland frequently.
The first inspiration for the leap second device came from the ancient pendulum. The invention of the pendulum in the 17th century allowed people to measure time for the first time to the nearest second. It is also because of the appearance of the pendulum that people finally say goodbye to the era when there is only one hand on the clock dial and can only roughly count. The pendulum completes a complete motion of “forward” and “backward” in the sound of “drop” and “mdash” and “md”; it also marks the time for two seconds. The invention of the balance spring has replaced the pendulum and also created conditions for the further miniaturization of the clockwork.
With the further improvement of the accuracy of pocket watches, watchmakers began to consider displaying the rhythmic swing of ancient pendulums in pocket watches. ‘One second and one hop’ design ideas began to brew in the minds of watchmakers. However, the balance with extremely high swing frequency obviously cannot directly play the role of ‘pendulum’, which requires a new, independent mechanism, or it is driven by another complex mechanism (such as constant power).
What does & ldquo; jump second & rdquo ;:
The French original meaning of Jump Seconds is ‘Seconde Morte’, which is translated into English as ‘Dead Beat’, and some are called ‘Second Beat’. The word Beat itself implies a bit of ‘cleanliness’. Earlier Rolex had a skip-second display watch equipped with a 1040 self-winding movement named ‘Tru-Beat’, which also implied this meaning. Compared with the smooth second hand, the “second jump” display has more rhythmic dynamics and is more mechanical.
的 & ldquo; Hertz & rdquo; Origin:
Hertz (usually abbreviated as Hz) is a physical quantity that records the number of arc-shaped swings of an object in a unit time (such as 1 second), and usually represents a stable periodic phenomenon. Hertz’s English name comes from a great scientist, Heinrich Hertz. He confirmed the existence of radio waves in 1888, and also contributed greatly to electromagnetics, so the international unit system of frequency ‘Hertz’ was named after him.
