Pros And Cons, Ceramic Materials That People Love And Hate

Ceramic is everywhere, but not always easy to see. In the current watchmaking industry, ceramics is one of the most fashionable materials, and its quality is favored by many brands. Behind the highlights, ceramics presents us with a whole new world of different materials applied in different ways. It has various advantages, but also has a few defects that cannot be ignored.

   Ceramic materials were first used in watchmaking and date back to the 1980s. First of all, the ceramics mentioned here should not be confused with the ‘ceramics’ used in kitchen cabinets. The high-tech ceramics are involved here. There are many different types of ceramics. They share some common characteristics, and these characteristics are why they are so popular. Among the dozen or more different ceramic materials used in the watchmaking industry, alumina (Al2O3) and zirconia (ZrO2) are the most common.

   Ceramics are resistant to acids and are not easy to oxidize and corrode; ceramics are abrasion-resistant and are not easy to produce scratches; ceramics are hard and difficult to deform. These three characteristics make the ceramic case a great success. In addition, ceramics have also been used in the manufacture of movement parts for a long time, such as ball bearings located under the rotor, which have a very unique operating sound. But that’s not all. Ceramic gears are used in the automatic winding mechanism of IWC’s new 52000 movement. The main purpose is to reduce the wear of parts.

   It is often heard that ceramics are indestructible, but this is not entirely true. In fact, the manufacturing process of ceramics determines that this material must have both advantages and disadvantages. High-tech ceramics need to be pressed into the mold in the form of powder. The melting point of ceramic powder is extremely high, and it is impossible to melt and then dump it like metal. In contrast, ceramics are made by sintering: powder particles are fused and diffused to form a continuous whole. The advantage of this process is that there are pores inside the ceramic, which makes the material lighter. The density of alumina is 3.9 g / cm3, compared to the density of 4.5 g / cm3 of titanium. On the other side of the coin, pores in the ceramic can form cracks, which can cause catastrophic fracture.

   Don’t forget that ceramics are extremely hard, and there is a saying that is too bad. Ceramic structures are inflexible, impact resistant, and fragile. In real life, if you wear a ceramic watch scratching a hard object (such as a rock), nothing will happen; if you accidentally drop it, the case will be spared; but if you throw it forcefully, there is a danger of fragmentation. In terms of performance, ceramics are almost the opposite of stainless steel, which explains why the former is so difficult to process. High hardness and fragile, it is difficult to put proper constraints on it during processing. The forming and sintering stages are particularly critical, and any mistake can lead to serious consequences.

Jaeger-LeCoultre Cermet

   Another advantage of ceramics is that they are highly inclusive and can be combined with other materials to change properties. Richard Mill’s TZP ceramics come from the interaction of zirconia and yttrium oxide for better impact resistance. Hublot has injected liquid 24K pure gold into the porous boron carbide body with a mass ratio of 25% / 75%, which means that this unique alloy can be called 18K. It is both precious and scratch-resistant. This is the unique magic gold of Hublot.

   Another way to take advantage of ceramics is to induce a chemical reaction in the aluminum watch case. Panerai has put it into practice and the result is a material called ‘Composite’. The aluminum case undergoes an oxidation reaction in a vacuum environment. The aluminum on the surface is converted into alumina. This is the most common form of ceramic and is very scratch resistant. The problem is that the case retains the advantages and disadvantages of the original material: the texture is light and stretchable, but it is prone to dents. Jaeger-LeCoultre is also interesting to create-‘Cermet’ (cermet), which consists of a titanium frame, which is then reinforced with ceramics.

   Ceramics are both ergonomic and aesthetically pleasing: smooth to the touch and thermally insulated. Unlike titanium or steel watches, which quickly heat up in the hot sun, ceramic watches remain refreshing in summer. Most ceramics are natural black, which is also a popular color in the watchmaking industry. Unlike PVD or DLC surface treatments, the color of the ceramic is permanent, does not wear out, and does not dim over time. Some ceramics are naturally white, just like Chanel’s favorite J12 watch. Some ceramics are chocolate-colored. Ceramics can also be dyed as a whole, and Bell & Ross’s blue and green watches are a good try. In fact, Bellevue and Chanel use the same production facilities.

Chopard Women’s Watch-news Chopard

Chopard has launched two ladies watches-L.U.C Tourbillon Lady and Happy Sport Chrono Chocolat.
L.U.C Tourbillon Lady is an extravagant and gorgeous work that combines the brand’s capabilities in haute horology and fine jewelry.
Baguette diamond bezel, rectangular and round diamond inlaid dial, white diamond inlaid case and baguette diamond inlaid crown (total 8.60 carats), create this hand-wound mechanical watch, L.U.C 4T. Especially the small tourbillon with four superimposed tubes formed at 6 o’clock. Complete hand-polishing is also the style of COSC-certified watches, and has obtained a very high quality guarantee: PoinÇon de GenÈve (Geneva Seal). Selling rose gold and platinum quantitative series, for those very few noble people who hold this watch, they can rest assured that they will not damage their nails when they wind the watch. Chopard took all this into consideration and provided the customer with a platinum handle, through which they can be used to wind the watch to ensure that the watch can run for 9 days.
For more sports customers, (or not so rich people, but also …) Chopard has prepared a noble and sophisticated style-Happy Sport Chrono Chocolat. A larger watch with a chocolate-colored refractory ceramic fiber case, a rose gold rotating groove, five removable diamonds, and a synthetic rubber metal strap carved into a meandering undulation Dune pattern. Although it has a waterproof timing function, it is also excellent and elegant.

Writing A Day In Lange History

November 9, 1989 completely changed Lange’s fate. The fall of the Berlin Wall allowed Walter Lange to revive the family business that had been forced to suspend. Lange never thought that one day he could make a comeback in his hometown of Glashütte and complete a special task-revitalizing the fine watchmaking industry in Saxon. Those who used to be with Lange once again witness the coming of historical moments today.

   Two photos five years apart: the former was taken on November 9, 1989, and the crowd was at the Brandenburg Gate
Celebrating the reopening of the gate on the Berlin Wall in front of (Brandenburg Gate);
The latter was taken on October 24, 1994, and Lange launched it in the Dresden Palace.
The first watch collection in the new era of Saxony fine watchmaking.
  The fall of the Berlin Wall marked the end of a political struggle. Although Glashütte is far from the center of the political whirlpool, this small town on the southeast end of the former German Democratic Republic clearly felt the shock on November 9, 1989.
   Annett Cellar, who was in charge of financial accounting at the time, was one of Lange’s first employees after the reconstruction, and she followed the development of the situation nervously in front of the TV. She recalled that when a reporter asked when the new rules on freedom of travel would take effect, the moment an exhausted civil servant replied ‘immediately,’ she thought she had heard it wrong. Later, a friend called her one after another to make her sure it was true. ‘We can hardly believe it,’ she said. Watchmaker Ursula Göhlert was equally shocked. ‘We have to adapt to this new beginning. In Berlin, which is divided into two worlds by the wall, people have felt the division of the country more effectively.’
  The people of East and West reunited under confusion and joy. Gudrun Pahl, who now works in customer service, understands the storm from a Western perspective. When she saw photos of people swarming across the border, she really understood the beginning and end of the incident. Britta Bäurich, who works in the sales department, is like most people. After learning about the fall of the wall through the news, he has ‘an indescribable feeling’ and excitement. Can not help but be mixed with doubt. Christoph Schlencker, the head of the testing laboratory, recalled: ‘At the time, we were worried that the gates would close again. A few days later, things became clear: the gates really reopened. . ‘

Earlier Lange employees were: Helmut Geyer, Annette Sina, and Christoph Schlusky
   Many people travel to Berlin, Munich and Stuttgart in the west or visit long-distance relatives immediately after travelling freely. But soon the question arises: what to do next? Design engineer Helmut Geyer set his sights on the declining watchmaking industry in Glashütte. Since the late 1970s, the former state-owned watchmakers have been producing quartz watches only, but in a market economy, these products are not competitive. Benito Lukas, the current director of the Lange Erosion Center, said: ‘The wave of layoffs was one after the other.’ He was one of the first victims, because he was young and not yet married. Several other employees, including Ursula Glet, were idle at the time.
   When Walter Lange expressed his intention to make watches again in Glashütte and hire employees for the new watch factory, news spread. Lange’s name still has a special meaning here. This is not only because of the brand’s long history and high prestige in the region, but more importantly, after Walter Lange was forced to flee to West Germany, he has always managed to keep in touch with the residents of his hometown of Saxony. Annet Sina’s grandfather used to make pocket watch movements for Lange, so after receiving the news, he hoped that his granddaughter could apply for a new Lange company. As for Helmut Geyer, he returned to be able to design complex mechanical watches again. Ursula Gelert also applied with the encouragement of her husband, although she initially had doubts as to whether she could meet the strict requirements of the company.
   Because East German training has always focused on manual skills, new employees at Lange have a good knowledge of mechanical watches. However, to make a watch priced over 10,000 marks in this new federal state, they could not fully adapt for a while. Therefore, the first step is to send employees to Switzerland to receive on-the-job training at sister company IWC, to understand the special requirements of advanced watchmaking. This includes superb sculptural and decorative techniques as well as computer-aided design. But most importantly, Günter Blümlein, Walter Lange’s business partner, persuaded this group of Saxon watchmaking pioneers to use bold design ideas and encouraged them to devote themselves to this. In a unique plan.

Before the fall of the Berlin Wall, people’s memories of time were hazy. The first Lange building was also depressed before it was renovated.

This is where the first female watchmakers made their watches in 1991
  After the training returns, they have to face the harsh reality again. The town of Glashütte lacked work equipment at the time, and everything had to start from scratch. At first there was only one computer-aided design workstation in the design office, and Helmut Goyer had to work in shifts with colleague Annegret Fleischer. The brand’s first plan was to make LANGE 1. Since it was decided from the beginning to adopt an asymmetrical dial design and an eye-catching large calendar display, developing a matching movement became the task of two designers. However, the design principle of the new large calendar display is not simple. The device must pass several tests to function reliably. At the same time, experienced designers need to suspend the design of the first watch movement and personally measure the size of the new room with a ruler. This is because the historic building that produced the Strasser & Rhode precision pendulum clock did not leave any architectural plans, and the building must be adjusted to meet the latest architectural requirements.
  At first there was no heating system either. In the winter, employees bring paraffin heaters from their homes for heating. However, from time to time, the old circuit system may cause the fuse to blow out due to excessive power. Despite the difficulties in the start-up phase, everyone’s excellent professionalism and deep knowledge base quickly came into play. In just four years, the first legendary Lange watch series was officially launched. Every piece of this watchmaking town marks the beginning of a new era.

Walter Lange took a group photo with the first four watches of contemporary Lange on October 24, 1994.
Of which LANGE 1 made Lange famous

   October 24, 1994 was a decisive day. The first four watches LANGE 1, SAXONIA, ARKADE and TOURBILLON ‘Pour le Mérite’ are subject to strict inspection by professional journalists and franchisees. After many rehearsals, this conference was meticulous and perfect. Everything is ready and under control, and only outside reactions are unpredictable. In the end, 123 watches sold out within a few minutes, and the last three were decided by lot. Outside the door of this important press conference, Lange employees were anxiously waiting for the results. When they heard the exciting news that ‘wholesale of watches were sold,’ everyone could not help but breathe a sigh of relief.
  ‘That feels wonderful,’ said Ursula Gelert. That night, Annette Sina and Britta Baruch sat together to fill out the first bills.
  Such a proud achievement was unexpected. These handmade Lange watches are instantly appreciated by collectors and enthusiasts. A small team of people that day has grown into a multinational company with operations in 62 countries. These four new era watches have also created 5 extraordinary watch series, with more than 70 models. This success story has made Lange a model for many watch companies. Walter Lange, who celebrates his 90th birthday this year, sums it up: ‘What makes me most satisfied is to be able to personally witness the town of Glashütte once again becoming the center of German watchmaking.’ What is firmly believed is: ‘As long as our watchmakers insist on creating the best watches in the world, Lange can go higher and further.’

Blancpain’s New Carrousel Question And Answer Sheet

Few watch factories in the world can launch the complex technology of the minute repeater watch, among which there are only a handful of brands capable of producing self-made minute repeater movements. Since the late 1980s, Blancpain has developed two unique minute repeater movements that have focused on and continue to develop. In 2010, Blancpain added a third movement-‘Le Brassus minute repeater’ with ultra-high technology.
  Blancpain’s original technology is clearly visible in this minute repeater. The minute repeater has a church bell ringing device, which means that the timepiece sound will be long and deep. After the device rotates around the movement for one and a half times, it will play a full and pleasant sound. For watchmakers, transmitting sound through the case’s starting mechanism has always been a severe test. Blancpain watch overcomes the difficult technology and hides the church bell bell in the exquisite case. Its volume and clarity are the masterpieces of choice for watchmaking. In addition, in order to highlight the performance of the three-question function, Blancpain specially developed a unique floating tuning device for this movement, and the movement runs more smoothly and naturally.
  The minute repeater has always been regarded as a very fragile and easily damaged treasure. Whenever the repeater asks, if the player wants to adjust the time, the movement may be damaged due to various circumstances. Blancpain’s new work resolves this situation. When adjusting the crown, the three-minute mechanism and the drive connection of the crown will be automatically interrupted to reduce the risk of damage to the movement. This time, the details should not be underestimated. In order to show its meticulous and sophisticated technology, the watch’s rose gold plywood and bottom plate are especially hand-crafted.
  The brand new Le Brassus timepiece is equipped with Blancpain’s one-minute floating carrousel, which was created two years ago. This technology has set a number of records in the history of the table, including the world’s first floating carrousel and the world’s first One minute Carrousel, and the world’s first carrousel minute repeater with a power reserve of 100 hours. Blancpain combines Carrousel with the minute repeater technology. The new Le Brassus minute repeater dial has a size of 45mm, with a rose gold case, a brushed white gold dial, and rose gold digital hour markers. The new watch’s open dial center and sapphire crystal back cover clearly appreciate the chic and intricate art of the minute repeater device, as well as the carving of the movement’s splint.

Vacheron Constantin Patrimony Traditionnelle 14-day

Vacheron Constantin’s latest model is equipped with an unparalleled 14-day tourbillon movement in an elegant low-key round case. This latest model of the Patrimony Traditionnelle line is also the brand’s first watch to meet Poinçon de Genève’s (Geneva hallmark) new standard for the Geneva mark.
The new Calibre 2260 movement was developed by Vacheron Constantin’s design engineers and watchmakers. The movement fully matches the design of the case. Its manual winding movement continuously outputs high-quality kinetic energy for the watch for up to 14 days. . Two sets of barrels are used in parallel, each of which is made of two barrels in series, so a total of four barrels are used, which means that they relax at the same time, but are four times slower than a single barrel.

The new Calibre 2260 movement consists of 231 components and two large bridges (instead of the three bridges of the previous Vacheron Constantin Tourbillon).
The tourbillon bridge is inspired by the brand’s iconic Maltese cross and showcases the excellent craftsmanship of each part of the movement, including a large number of internal corners, bevels that are completely handmade. It is completely handmade according to the ancient method. It is very time-consuming and labor-intensive to polish. It only takes more than 11 hours to polish the upper bracket of the tourbillon to achieve the best results.
The positions of the hour and minute hands driven by the Calibre 2260 are slightly off-center, while the 14-day power reserve is displayed in a 280-degree arc for improved readability. The 12 o’clock display and minute scale bezel on the silver opal dial are inspired by Vacheron Constantin’s rich cultural heritage.

Patrimony Traditionnelle 14-day Tourbillon is the first watch officially produced by Vacheron Constantin under the new rules of the Geneva Seal. The new standard is to certify the entire watch, rather than just the movement as before.
On the 125th anniversary of the birth of the Geneva Seal, this world-renowned seal has further improved its standards in response to the vigorous development of the watchmaking industry, the rapid development of watchmaking technology and the continuous innovation of materials. The new standard requires regular sampling of all manufacturers applying for certification and a rigorous seven-day precision test (simulated wearing design).
