Tianjin Seagull Watch Group ‘postdoctoral Research Station’ Unveiled

At 10 am on September 20, 2011, the unveiling ceremony of Tianjin Seagull Watch Group’s ‘Postdoctoral Research Station’ was held at the Airport Seagull Industrial Park, marking the official launch of the ‘Seagull Postdoctoral Workstation’. The unveiling ceremony.
    Seagull’s ‘Postdoctoral Research Station’ hires Professor Du Ruxu, a doctoral tutor at the Chinese University of Hong Kong, as a postdoctoral research station tutor.
    The Seagull ‘Postdoctoral Research Station’ was approved by the Ministry of Human Resources and Social Security to build the station in November 2010, and was licensed on March 14 this year. It is the first post-doctoral scientific research station in the watch industry in China, and has been approved by the ‘National Office of Management of the Ministry of Management’ to independently recruit post-doctoral researchers. It is the first in Tianjin and the third post-doctoral station in China to be qualified to recruit post-doctoral researchers.
    The Seagull Group is the birthplace of China’s first mechanical watch, with 56 years of technology and cultural accumulation. Over the years, the Seagull Group has adhered to the development of science and technology and insisted on independent innovation and development. It has mastered the ‘three classic technologies of the world watch (Tourbillon watch, minute repeater watch, perpetual calendar watch), and the’ Seagull Watch ‘has become an independent core technology ‘No. 1 domestic’ watch brand. In 2009, Seagull Technology Center was identified as ‘National Enterprise Technology Center’. This year, Seagull was identified as the first ‘National Technology Innovation Demonstration Enterprise’.
    The Seagull Group inspires the responsibility of developing the Chinese watch industry and establishes the goal of ‘aiming at the same level in Switzerland and marching towards a well-known international brand’. And he is well aware of the gap between himself and Switzerland and Germany, and is making unremitting efforts to use domestic and foreign resources to carry out cooperation between industry, university and research, and strive to solve the problems of technological development, process innovation, manufacturing level and brand development.
    The research topic of the Seagull postdoctoral workstation is: ‘Application and Industrialization of MEMS Technology in Mechanical Watches’, which is a breakthrough innovation in the design and manufacturing process of mechanical watches. The expected goal is to improve the accuracy level of the Seagull cardless coaxial tourbillon watch and realize the application of the silicon escapement speed regulation mechanism in the Seagull high-end watches. At present, the Swiss watch industry is still in its infancy in the microfabrication of silicon materials. Seagull has pioneered the country and synchronized with Switzerland.

Bright Winter Lights Tasting Audemars Piguet Royal Oak Series Diamond Watch

The emergence of the Audemars Piguet Royal Oak has overturned the traditional watchmaking aesthetics of formal dress. The bold and innovative design of designer Gérald Genta created the Aquarium in the quartz storm. A devious road. Speaking of the Audemars Piguet Royal Oak series, the name is quite rooted, taken from the RoyalNavy Royal Navy ‘RoyalOak Royal Oak’ ship, because the shape of this series of watches is derived from the ‘RoyalOak Royal Oak’ ship . But the name of the ship is in honor of a legendary oak tree. In 1651, King Charles II of the United Kingdom defeated in the First World War. In order to avoid the attack of the pursuers, he hid under an oak tree, which was later named ‘Old Oak Tree’. Last year, Audemars Piguet launched a sparkling masterpiece for the Royal Collection, inlaid with brilliant diamonds into wrist timepieces, hooking people’s hearts and souls, adding dazzling light to the masculine and tough sports style.

Shining the bright light of winter

 
    The classic octagonal case design, hexagonal screws and so on are all the iconic designs of Audemars Piguet Royal Oak, deeply rooted in the series of models. Apart from these, one of the biggest highlights in this watch It is diamond setting. The watch’s lugs, lugs, bracelet and dial all use a closed inlay process, which is the oldest inlay process. A total of 1135 brilliant-cut diamonds and 25 rectangular-cut diamonds have been applied to the watch, which makes the watch a radiant effect.

Watch real shot

 
    The case is made of 18K white gold, and the bevel and sides are polished by three processes: brushing, mirror polishing and matte polishing. The bezel and lugs are set with dense diamonds, which makes the watch bloom at 360 degrees. .

    The lugs and case are integrally formed, and the turning lines are clear, and the overall structure is simple and British.

   18K white gold diamond dial with rectangular cut diamond hour markers and white gold fluorescent royal oak hands, starlight. A date display window at 3 o’clock adds a practical feature to the watch.

   The same platinum crown is located on one side of the watch. The hexagonal shape and the hexagonal screws on the bezel have the same effect and complement each other.

   The watch has a built-in Audemars Piguet Calibre 3120 movement that provides a 60-hour power reserve. The movement is equipped with a balance spring with fine-adjustable riser and a screw-type adjustable support screw. The bridge is chamfered with diamonds and is decorated with an inverted hairspring. The 22K gold oscillating weight is also carefully carved and engraved with the brand ‘AP’ logo.

   The ‘decreasing’ link bracelet retains the design characteristics of the Royal Oak watch bracelet, and at the same time, it is beautifully crafted with diamond setting.

Summary: The Royal Oak series, which was born in 1972, has always been sought after by table friends. It represents a kind of attitude that breaks the tradition and takes the risk. The same goes for this 2018 diamond watch. The harmony between the iconic Royal Oak design and the diamond created the glamorous wrist watch.

Real Trajectory Around The Sun: Time Equation Watch (On)

You know, there are 365 and a quarter of a year, and a day can be divided into 24 hours. If your watch is accurate enough, only the second hand can see the difference between the watch and the standard time. You may also know that the time calculated by the watch is actually based on the orbit of the human’s imaginary earth around the sun, so every year is equal and every day. But everything is not perfect, you know, the earth’s true orbit around the sun looks like a kidney? This kidney-shaped track and the ideal track have only four repeated dates, and the rest of the time, spent in the gap. One doesn’t need a watch that displays the true solar time, but can’t help but know the truth behind such a timing tool.

The earth’s orbit around the sun is actually not a circle, but an oval-shaped kidney shape. Only on the four days of April 16th, June 14th, September 1st, and December 25th each year, the ideal circular orbit intersects with the true orbit, and the average solar time will be consistent with the true solar time.
   The way the ancients used to define a ‘day’ is the time it takes the sun to pass through the same fixed point in the sky twice (that is, the time that the earth rotates a week). The time that the earth makes one revolution around the sun). If the orbit of the earth around the sun is a perfect circle, and the axis of the earth is also facing the sun instead of tilting, then dividing a year into 365 days and 24 hours a day is perfect. but it is not the truth. The orbit of the earth around the sun is an elliptical kidney-like shape. That is to say, the distance between the earth and the sun is different on different dates. People use it in daily life and use the ideal perfect circular orbit to calculate ‘ There will also be a slight difference between the ‘average solar time’ and the ‘true solar time’ presented in real orbit. This difference is the so-called ‘time difference’, which is about plus or minus 15 minutes, or more precisely, between plus and minus 14 minutes and 22 seconds and minus 16 and 23 minutes; only on April 16 and June 14 The four days, September 1 and December 25, the ideal and the true orbit intersect, and the average solar time will be exactly the same as the true solar time. This is what the time equation watch is about.

Audemars Piguet Royal Oak Equation of Time
   This Audemars Piguet watch has a perpetual calendar function besides the date and day of the week at 6 o’clock, the month, moon phases at 12 o’clock, and the leap year. It also has a rare sunrise and sunset time, which will be daily The raised and lowered status is displayed on the dial with hands. This approach of course increases the complexity of the movement, but in fact, its principle is the same as the time equation, enclosing the curve of sunrise and sunset time in a year into a plane figure (similar to an oval shape, depending on different regions) (Fixed) and make a cam that rotates once a year, and then use the lever with a rack to link the pointer on the faceplate; as the cam pattern fluctuates, the sunrise and sunset pointers will also move back and forth.
   Since the sun rises and falls at different places on the earth at different latitudes, Audemars Piguet has created its own cams for 250 cities around the world. And the time of “midday” in each city is also slightly different, so the time scale of the positive and negative 15 minutes on the outer circle of the time scale is opposite to the time equation scale. You can also see the city set by the watch and its average noon time. The location of the city name and time scale is actually meaningful. Every day, when the blue-steel hands that indicate the time equation overlap with the minute hand, you can directly read the time when the city’s real solar time reaches 12 o’clock on the day of the day (such as Le Brassus, where the Audemars Piguet factory is located on April 13th). It was about 12:35, which is 35 minutes and a half from the midday of the mean solar time). This design is like a sundial, but it also integrates the wisdom of the ancients into a small timepiece.

   If there is any function that is most suitable for combining with the time equation, it must be a perpetual calendar! Because the perpetual calendar itself is a function of an actuarial calendar and human achievement in astronomy, like the equation of time, it represents the relationship between the sun and the earth. Many of the time equation models launched by various brands include the perpetual calendar function; however, in addition to representing the difference between the true solar time and the average solar time by plus or minus 15 minutes, it is more clear to add a minute hand Coaxial hands directly indicate true solar time; this is not a feature that all time equation watches have.

   Baobo first introduced the chronograph work with real solar time hands in 2004. The Calibre 3863 automatic winding movement also has a perpetual calendar that can automatically interpret big, small months and leap years. This is a breakthrough in the history of the brand and is also a breakthrough in the watch industry. Innovative move (then Bao platinum also launched this big fire enamel dial). Under the numerous messages, the arrangement of the face plate is still organized; the difference is the moon phase, which is not displayed in a half-moon window, but instead uses the retrograde hand to display at 11 o’clock. Perhaps this will reduce the beauty of the traditional moon phases, which are sometimes hidden, but sometimes hidden, but Bao Platinum chose to focus on the 6 o’clock position, which is the key to calculating the time equation-the kidney cam. Even if it runs slowly (one rotation per year), you can still appreciate the undulation of one end of the lever according to the shape of the cam; and through the rack and gear train on the other end to the center and 1 o’clock, it is the real sun. Time and time equation.

Girard-Perregaux 1966 Annual Calendar and Equation of Time
   As mentioned earlier, the perpetual calendar is very suitable for displaying astronomical calendar functions in mechanical timepieces along with the time equation. But if you consider that in real life you don’t have to watch to automatically jump from February 28 or 29 to March 1, in fact, it is enough to have an annual calendar function. However, many models on the market that have the function of time equation also use the perpetual calendar mechanism, or the tourbillon, which is also one of the three major complex functions. There are really not many models that want to be simple and can mechanically interpret the true solar time. Girard Perregaux 1966 Annual Calendar and Equation of Time is one of them.

   The 1966 series is full of classic styles in Girard Perregaux’s product line, including a round case that is never tire of, linear and stick-shaped hour markers, and elegant willow-shaped hands, exuding beauty with a simple design. And this almanac time equation watch expresses its own characteristics with an asymmetrical dial configuration. The date dial at 1:30, the month window at 7 o’clock, and the small seconds at 9 o’clock. Time information required for daily life; at 4:30, a time scale of 15 minutes is indicated by a blue steel pointer in the shape of a willow leaf. On the whole, although the dial is rich in appearance, it is not too cluttered; it is low-key and does not have a distinguished texture. Built-in GP03300-0010 self-winding movement. From the sapphire crystal case back, you can enjoy the ring-shaped Geneva ripples on the 18K rose gold automatic plate, Geneva ripples on the splint and machine plate, fish scales, chamfers, polishing and other GP marks Check the modification.
