Throughout the evolution of the Montblanc Nicholas Kays chronograph series, it seems that they are closely related to the turn-based time display mode: the first generation of Montblanc Nicholas Kaise chronographs took the lead in replacing the dial Chronograph hands to display 60-second and 30-minute timekeeping; then the turntable system extends to the second time zone display; Montblanc Nicolas Riesus Rising Hours, which appeared this year, is equipped with two overlapping dials, displaying 12 The hour advances, and at the same time it shows that day and night.
Although Montblanc’s Nicholas Kays day and night chronograph has a revolutionary hour display, it has always been closely linked to the basic spirit of Montblanc’s first model with a rotating dial and a fixed hand to display cumulative chronographs; this year’s turntable concept is in focus In the hour display mode, it is refreshing that the engineers of the brand have developed the fun of integrating the day and night display with the hour display.
Day and night display, new and interesting
Throughout the ages, the hour-of-day display is not new: the hour number advances once every hour at a fixed mark, and the minute hand rotates in the traditional way, but Montblanc Nicolas Kies chronograph chronograph is a revolutionary: Like the other Montblanc Nicholas Kays chronograph models, the new work takes the off-center hour dial layout, but the hour hand is discarded. There is an arc window at 12 o’clock. When you see the Arabic numeral hour dial, the number facing the triangle mark is the current one. hour.
At first glance, this mode is similar to other timepieces, but if you look closely, you will see that the hour number will change with day and night: the hour number at night is light blue, the day is black, and the day and night are obviously different. Set the date to ensure that the date numbers advance accurately at midnight (not at noon).
Montblanc new movement with patented day and night display technology
This brand new time display system is derived from the patented technology of Montblanc’s new self-made MBR220 movement. There are two overlapping discs with 12 hollowed out Arabic numerals on the bottom. The light blue and black on the disc each represent half. The light blue represents At night, black represents the day, and the two colors underneath, and the numbers change color with the day / night. The upper number advances hour by hour, and the lower turntable rotates at the specified interval and speed, showing the correct color area. This display mode is controlled by a cross-shaped part equipped with two cams, one of which is mounted on the drive lever of the day / night turntable, and the other cam is connected to the extension of the hour drive lever; the two cams have special contours The shape makes the two cams slowly rotate between 9 am and 3 pm (and between 9 pm and 3 am), but during this time the day / night turntable is fixed until 3 am and afternoon At 3 o’clock, the two cams are engaged to accelerate the day / night turn until the two teeth on each side are engaged. The day / night turn is no longer accelerated and synchronized with the digital turn. The latter situation is at 4:30 in the morning As of 7:30 a.m. (and 4:30 p.m. to 7:30 p.m.).
Then, the day / night disc is decelerated from 7:30 am to 9 am (and 7:30 pm to 9 pm) until the joints are completely separated, and the day / night disc stops rotating.
The operation of this patented technology can be seen twice a day: at 6 am every day, the left half of the hollowed-out 6 is still light blue, but the right half has seen black, which means that the night is about to dawn; at 6 pm, 6 The left half of the word is black but the right half has seen light blue, which represents the sunset of the western mountains and the night.
In addition to the two discs, day and night, there are four discs each performing their duties: the position at 9 o’clock is the day, the position at 3 o’clock is the date, and the remaining two are 60-second and 30-minute timers. The technical concept of this integrated chronograph movement is basically the same as other chronograph chronographs. The chronograph is controlled by a column wheel and a vertical clutch with minimal wear. It is set at 8 o’clock with a single push of the chronograph button. Gesture of pressing. It is worth noting that the teeth of the transmission wheel system have been refined to improve the efficiency of power transmission and have the advantages of less loss and less energy consumption. MB R220 automatic refining movement has excellent refining efficiency. The power reserve of the double spring drum is about 72 hours, and the torque output remains stable for a long time. The swing frequency of the large 10mm screw balance is 28,800 times (4 Hz) per hour. 12 mgcm2 to ensure accuracy and stability during travel.
Tradition and aesthetics
The appearance of the day and night chronograph inherits the unique style of the Montblanc Nicholas Kaiser watch series, but the layout details are clear at a glance: the V-arm at 6 o’clock holds the jewel bearings of the two chronograph dials, as Grinning, one side is a 60-second timer and the other is a 30-minute timer, each with a fixed hand; the day / night hour dial at the upper glass center shows the current time by the hollow minute hand and digital dial. The half-curved window on the left shows the day of the week, and the date on the right; the other places are decorated with classically beautiful machine-engraved wheat grain patterns.
The new 18K rose gold case has a diameter of 43mm, and the stepped lugs are exquisitely crafted. With a brown alligator strap and triple discount in 18K rose gold, the switch is easy and simple. The 18K rose gold crown is full and carved with fine pits. , Inlaid with the mother-of-pearl Montblanc six-pointed star trademark; curved crystal glass with double-sided anti-glare treatment, the back of the crystal is also set with crystal glass, showing the operation of the rose gold rotor and the exquisite workmanship of the movement.
Also available in platinum with a limited edition of 28 pieces, with a grey crocodile leather strap and platinum discounts, and non-limited stainless steel models with a black crocodile leather strap and discounts.
Tribute to Nicholas Kasch (1781 – 1866)
Montblanc created the Montblanc Nicholas Kaiser chronograph series based on the timer technology invented by Nicholas Kaiser to pay tribute to the talented watchmaker who invented the timer. The dot ink timer invented by Kasch passed the test in 1821 and was awarded a technology patent in 1822. The timer he invented was driven by a movement with two white enamel turntables, with minutes and seconds on the surface, a fixed pointer on each side, and a needle connected to the ink pouch. Press the button to start the timing program. Press the pointer with the ink sac to the turntable, and the ink will leave a mark on the turntable to record the meter. After reading the timing record, the ink will be erased and the next timing program can be started. This technique can be called the ancestor of ‘writing time’: the word chronograph is composed of the ancient Greek chronos (time) and graphein (writing). To commemorate this ground-breaking chronograph technology, Montblanc launched the Montblanc Nicholas Kaiser chronograph in 2008, replacing the chronograph hands with a chronograph turntable. This heritage of writing time cleverly connects the Montblanc watch factory with the Montblanc writing culture.
