The Ultimate Mechanical Chronograph Watch With Outstanding Performance

Breitling challenged one of the most sophisticated and sophisticated clock manufacturing technologies in the contemporary era and successfully launched its own double-tracing chronograph movement, which once again demonstrated the brand’s extraordinary capabilities in the field of chronograph technology. Dedicated to creating professional Breitling ‘Wristwatch’, its carefully developed new Breitling self-made B03 movement (two patents have been applied) uses innovative structures to ensure the best accuracy, robustness and reliability. Now, Breitling has decided to present this major technological leap to its supporters through its most famous aviation chronograph series (Navitimer). The new model is available in stainless steel and red gold, with a unique bronze dial.

   There are very few watch brands with home-made mechanical chronograph movements, and it is rare to see a brand with a patented double-tracking chronograph movement developed and produced entirely in-house. With the heavy debut of Breitling’s homemade B03 movement, which has the Swiss Official Astronomical Observatory certification (COSC), Breitling once again confirms the brand’s leading position in the field of mechanical chronograph watches, and strengthens its role in the development of chronograph watches. Key role. For nearly a century, Breitling has set a number of key milestones in this field; in 1915, Breitling pioneered the first independent timing button at 2 o’clock; in 1934, Breitling invented the second independent timing button; 1969 In 2015, Breitling led the world’s first self-winding chronograph watch. One of Breitling’s most classic wristwatches, the famous 1944 Duograph, is also an indispensable part of this epic legend; this watch is equipped with an ultra-thin double-tracking chronograph movement. Watch collectors’ favor and pursuit.
Performance comes first
   The double-tracing chronograph is one of the most difficult mechanical watch functions recognized in the industry; the watch is equipped with two central chronograph hands that overlap each other. After the push-travel button is pressed, the two hands are separated from each other, and one hand is stationary. It is used to measure the middle time (segmented timing), and the other one continues to run; after pressing the chase button again, the stopped hand will immediately ‘catch up’ (in French, ‘rattraper’) the running hand. These ‘super-complex’ watches are usually produced only in small batches and require a lot of time for watchmakers to adjust and rate them (correction of the clearance between the pin wheel and pinion, spring tension, and clamps Depth of penetration, etc.) In the process of developing a self-made double-tracking chronograph movement, Breitling has used innovative methods to create this unique mechanism. Guided by the brand concept of ‘professional wristwatches’, Breitling, a technical watch expert, strives to ensure that the watch still has excellent ruggedness, accuracy and reliability, while mass production, just as the brand is above The slogan proposed in the 1940s-‘Quality in series’. Breitling’s goal is to develop a system with the fewest components to ensure the best performance, to avoid the lengthy tuning process. In short, to find a simple and efficient solution for complex problems. In order to achieve this goal, the Breitling team took many years to carry out in-depth research and testing.

Rethinking traditional mechanisms

   Energy levels are one of the main challenges faced by developers of dual-tracing chronograph movements. Repeated start and stop of the double chasing hands will produce different energy requirements, which will not only affect the timing accuracy, but also weaken the watch’s power reserve. One way to solve this problem is to equip the movement with a separate system for separating the tracking needle when the time is stopped-this is the way Breitling uses. However, in order to find a more reliable and effective solution, Breitling’s engineers and watchmakers re-examined and transformed the traditional structure of the double-tracking hand timing device. They have developed two innovative designs and have applied for patents for them. One of the breakthroughs is related to the independent system mentioned earlier; the driving device of the follow-up movable rod is usually designed with a cylindrical pin, and once the component is smaller than a certain size, it will be particularly complicated to produce. Breitling replaced the traditional latch design with special stampings, which not only realized a more precise shape structure, but also helped to strengthen the robustness of the part. Thanks to this independent system, the chronograph no longer affects the chronograph accuracy and power reserve of the watch. Another innovative technology is related to the braking mechanism of the chase needle; in traditional design, watchmakers will use a round wheel with a clamp positioning (smooth periphery or with ultra-fine gear teeth) to achieve this function . This kind of braking system is not only difficult to produce, but also affects the accuracy to a certain extent. Breitling engineers took inspiration from bicycle brakes equipped with rubber pads, and proposed a new design concept of adding a ring-shaped seal around the wheel and restricting the clamps by pressing. This can not only bring accurate braking effect, but also help simplify production and further improve the reliability of the system.

Smart construction

   Breitling based on the earlier developed 01 movement, carefully developed and built a new B03 self-winding double-tracking chronograph movement. Breitling’s own 01 movement is an excellent intelligent platform that supports other useful functions including dual time zones and world time display, bringing unprecedented ease of use and convenience. Breitling’s self-made B03 movement combines the advantages of this high-performance ‘engine’, including a 70-hour power reserve (to ensure better rating stability), and an innovative modular design structure. The new movement’s dual tracking device only contains 28 parts; Breitling reassembled and installed most of these parts on a module located between the base plate and the calendar device, which effectively simplified the production, assembly and maintenance of the movement; Breitling can remove this module directly from the movement, and maintain and repair it. Like all Breitling movements, the new Breitling B03 movement is certified by the Swiss Official Observatory (COSC), which represents the highest benchmark for accuracy and reliability.

Breitling Aviation Chronograph Dual-Chase Watch: Extraordinary Power at Your Fingertips

   In order to better highlight this new high-performance ‘engine’, Breitling chose its world-renowned Navitimer to present this new technology. Since its introduction in 1952, the Breitling Aviation Chronograph has become one of the originators of various mechanical chronograph watches around the world. The Breitling Aviation Chronograph Dual-Chase Watch comes with a 45 mm case and comes in two different versions-a stainless steel version and a limited edition of 250 red gold with a transparent sapphire case. Both watches feature unique bronze dials that complement the silver chronograph and inner bezel, perfectly embodying the classic look of the aviation chronograph series. This watch also has an extremely delicate design: the chronograph watch usually bears the brand’s famous ‘B’ and anchor logo on the end of the watch, but in this watch, this classic design is Divided into two-the end of the red chronograph hand with a ‘B’, the end of the chase with an anchor pattern. This means that when the chasing needle stops, the two patterns will be separated from each other; when the pointers overlap, they will merge into one, showing the Breitling classic logo. At 3 o’clock on the crown, there is a chronograph push-button, which can be used to count time and compare the results of multiple competitors. This ultimate mechanical masterpiece with outstanding performance will open a bright new chapter for the Breitling Legend series.
