In the evolution of the Tudor chronograph, the third generation 9400 series PrinceOysterdate watch released in 1976 set off a revolution, because this marked the first time Tudor used the famous Valjoux7750 automatic movement for assembling a chronograph. From the appearance, this new series adopts a more traditional layout, with sub dials at 6, 9 and 12 o'clock respectively, while the 3 o'clock position is reserved for the date display window. The 79100 series, introduced in 1989, has not  changed much and is still driven by Valjoux 7750. The movement has a vibration frequency of 28,800 vibrations per hour (4 Hz) and is controlled by an oscillation pinion. It is highly reliable and highly praised. The last series with historical significance is the 79200 series, which came out in 1995, that is, 'blue crystal'. The series uses the Valjoux7750 movement, but the case outline is softer and rounder. Other design innovations include a black aluminum bezel with a tachymeter scale, a silver dial with a cream sub-dial, and a sapphire crystal with a Cyclops convex lens (replaces the traditional Plexiglas mirror).

Patek Philippe will celebrate the tenth anniversary of the establishment of the cutting-edge research department next year (not this year, although it came out in 2005). The achievements of this department are mostly focused on parts, including innovative breakthroughs that influence the future development of the Swiss watch industry. But it's not all, because there are many well-resourced brands that are also committed to the research and development of silicon materials and their applications. In other words, the road is narrow, and competition is widespread. Regardless of the type of material, or manufacturing or innovative applications, fierce competition is everywhere. The start-up years of some projects are even before the establishment of cutting-edge research departments.

Case: The Omega Seamaster 300-meter diving watch was 41 mm since its introduction in 1993.  The case size of the new watch is 42 mm, which is slightly larger. The watch has a helium exhaust valve at 10 o'clock. The new seahorse 300-meter diving watch has modified the shape of the helium exhaust valve. It was cylindrical before, and now it is modified into a conical shape with a narrow upper and lower width. The thickness of the new hippocampus at 300 meters is 13.5 mm.

Mr. Walter von Kanel, President of Longines, said: 'We are very satisfied with this year's Baselworld and this exhibition is really a success.'

When the first generation of chronographs (1913 Longines and 1916 Breitling) came out, the situation became more interesting. The smaller the limited available space, the more prominent the opposition between space and detail. Longines and Breitling chose to cut the outline of the chronograph element, the sub-dial is restrained and low-key, and unnecessary mark marks are discarded as much as possible. This is also the model followed by Patek Philippe and other watchmakers in the next ten years: watch design is prioritized, intended to show the strength of manufacturers, not for practical purposes. Comparing it with a pocket stopwatch, such as the original TAG Heuer Mikrograph from 1916, a clear difference can be seen.

Longines Concas V.H.P. ultra-precision series represents a new achievement in the field of quartz, combining ultra-precision, high technology and dynamic appearance, showing the brand's distinctive elegance. This series of watches is equipped with the exclusive movement developed by ETA for Longines. The movement is known for its excellent timing accuracy, and the analog display shows that the annual error is only ±5 seconds. At the same time, the movement uses a GPD (gear position detection) system, which resets the hands after the watch is affected by the magnetic field. In addition to these very attractive qualities, the movement is also equipped with a very long-life battery and adds a perpetual calendar function.

On the other hand, because the moon phase  cycle find out more is 29.5 days, the common moon phase display is difficult to accurately grasp the length of this cycle, but Omega's high-precision mechanical device has overcome this problem well. The moon phase of the Omega Speedmaster Series Moon Phase Observatory's moon phase display only needs to be adjusted once every ten years of operation. Not only the moon phase display, the most important time display of the watch is equally accurate. This watch has passed the certification of the Swiss Federal Institute of Metrology (METAS), becoming the first Speedmaster watch to obtain the 'Best Observatory' certification, its accuracy and performance are in a leading position in the watchmaking industry.

The TAG Heuer Carrera Mikrograph Centennial model is equipped with a unique self-produced movement-the TAG Heuer Mikrograph 1/100 second movement released in 2011. This is the first mechanical chronograph movement that integrates a column wheel. The central hand indicates 1/100 second.

The Brazilian football legend has captured the hearts and minds of millions of fans around the world because of its unique enthusiasm and spirit. This great achievement has been mainly created by the Brazilian Football Federation (CBF, Confedera o Brasileira de Futebol) for nearly a hundred years. In order to pay tribute to it, Parmigiani, a top watch brand with a close relationship with sports, formally established a cooperative relationship with CBF and became its designated sole partner. To this end, Parmigiani also specially created a unique Pershing series to commemorate this collaboration.

Lady-Datejust's Oyster case guarantees a water resistance of 100 meters (330 feet), which is a model of sturdy elegance and perfect proportion. The uniquely shaped middle case is cast from the original solid 950 platinum or 18ct gold. The triangular bottom cover is screwed down with special brand-specific tools to completely seal the case, which can only be opened by Rolex watchmakers.

At a glance, the special features of the DefyFusée Tourbillon movement are clear and easy to understand. The design of the bridge spokes is further enlarged by two-tone retouching, in which the top of the satin retouch is blackened, and the polished edges are light gray rhodium. The layout of the bridge board makes the setting of various functions and complex functions more balanced. In the upper part of the movement, you can appreciate the unique concept of the sesame chain constant motion mechanism. The mechanism consists of 575 individually hand-assembled parts, using bold blue processing, setting a precedent. At the other end of the 6 o'clock position, the tourbillon frame has a new construction and is equipped with an eccentric balance wheel that rotates once every 60 seconds. Like the sesame chain, the tourbillon frame presents a striking blue finish, enhancing the visual effect of DefyFusée Tourbillon's unique moving parts. The power reserve display is located at 4 and 5 o'clock on the edge of the dial and is indicated by a pointer with a red tip. This function is very useful when manually winding the watch. The DefyEl PrimeroFusée Tourbillon watch has a 50-hour power reserve.
