Watch found Nobel Prize won
Famous Swedish chemist, inventor of nitroglycerin explosives Alfred Behnhad Nobel
The Nobel Prize, founded as a fund, is part of the legacy of Sweden's renowned chemist Alfred Bernhard Nobel, the inventor of nitroglycerine explosives (31 million Swedish kronor). The Nobel Prize consists of five awards in physics, chemistry, physiology or medicine, literature and peace. It was awarded for the first time in 1901 to those who made a significant contribution to humankind in these fields in the previous year in accordance with the annual interest or return on investment of the fund. The Nobel Prize includes gold medals, certificates and bonuses.
At the time of the first prize presentation in 1901, the prize money per individual was SEK 150,000, which was equivalent to a 20-year salary for a professor in Sweden. In 1980, the single prize of the Nobel Prize reached SEK 1 million, SEK 6 million in 1991, SEK 6,500,000 in 1992, SEK 6,7 million in 1993, and SEK 9 million in 2000 At that time, equivalent to about 1 million US dollars). From 2001 to 2011, individual bonuses were SEK 10 million (equivalent to about $ 1.45 million in 2011). Gold medal weighs about 270 grams, containing gold, medal diameter of about 6.5 cm, the front is the Nobel statue relief. Different awards, medals on the back of different patterns, each award-winning design and vocabulary are not the same. Ceremony grand and simple, the annual attendance is limited to 1,500 to 1,800 men; men must wear a tuxedo or national costumes, ladies wear dignified evening dresses; the white flowers and yellow flowers used in the ceremony must be from the Italian town of St. Morey Bell passed away).
Who won the Nobel Prize for the watch industry it?
Charles Édouard Guillaume (1861-1938) 
Charles Édouard Guillaume, born February 15, 1861 in Fleurier, Switzerland, is located here. He died in France in 1938 and his father was Swiss watchmaker, earliest as a ship clock and as director of the International Bureau of Weights and Measures. The old gentleman married AMTaufflieb in 1888 with 3 children.
Invar or Elinvar 
Through a large number of experiments found that when the nickel content of 36%, the thermal expansion coefficient of inflection point, the lowest
In 1920 won the Nobel Prize in Physics. Nickel-iron alloy with a coefficient of thermal expansion close to zero was found and named by him as Invar or Elinvar with the lowest coefficient of thermal expansion at 36% nickel. This material is not only hard, corrosion-resistant, low thermal expansion coefficient, but also has good magnetic properties. Is a very good performance of the metal material.
Antique double truncated Guillaume balance, above the counterweight yellow gold, white platinum, extravagant 
Antique double truncated Guillaume balance was the expensive new material for antique pocket watches, the use of Guillaume balance are high-end stuff!
Although Ivana won the Nobel Prize, the time it takes to make a balance wheel is not long, as new, better discoveries are made on the material behind.
Now most of the balance wheel is Glucydur beryllium copper alloy 
Modern balance wheel
The second peak of material advancement was the subsequent progress of Invax invented in 1930. The Nivarox alloy, with the addition of other elements other than nickel, contained 54% iron, 38% nickel, 8% chromium, 1% titanium, 0.2% 0.8% manganese, 0.9% beryllium and less than 0.1% carbon. The temperature tolerance of balance and hairspring using Nivarox is 0.3 seconds.
The third peak, which is currently the most widely used material, is Glucydur beryllium-copper alloy. Inva steel makes the balance no longer use bimetal truncated structure. Glucydur beryllium-copper alloy canceled the screws on the balance wheel, smooth swing (smooth Glucydur balance) popular. Light swing greatly reduces the difficulty of manufacture and adjustment balance, a substantial reduction in watch manufacturing costs. The price of this alloy is about 200 yuan per kilogram, not only the low coefficient of expansion, but also does not have a magnetic, hard Brinell hardness of 400, and particularly corrosion-resistant. The current balance of the Glucydur beryllium bronze is standard on high-end watches. In ancient China there were many legends about swords, such as Zhanlu Sword and Yuejian Goujian Sword, both of which were bronze wares of the ages, which might be the beryllium bronze sword made by the ancients.
