Tudor Tudor in the end is what kind of brand? It is often said that it is the younger brother of Rolex. It is the existence of the same watch factory, different production lines, and different levels. Indeed, at the beginning of its founding, Tudor was defined by Hans Wilsdorf as the "President of Civilians." As the founder of Rolex discovered in the promotion of the British, the high price of Rolex made it difficult for the local people to accept, Tudor was born. Tudor Kai Cheng Biwan bronze models Tudor's early product appearance has a strong Rolex atmosphere, including the case back cover, strap, crown, etc. will often find the shadow of the crown. Of course, there is the large and small rose logo on the disk, which is a symbol of the long-term rule of the British Tudor dynasty. The classical classics are also the topics most talked about by Tudor. In 2009, Tudor repositioned and began to transform, constantly injecting new elements into the models. In 2015, Tudor took out the first self-produced movement in the brand's history - the MT 56 series, MT stands for Manufacture Tudor, and changed the situation where only ETA, Valjoux, etc. were used in the past. The introduction of new movements will come to fruition – the rudder will need to be changed, and the ETA movement will be in short supply. This has created the MT series, and many people are not worried about the quality of the new movement, because even if it is ETA, Tudor has played top level. Another joke, if Tudor is shameful outside, Rolex's face can not hang, just as parents will not allow children to embarrass themselves as a result of nonsense. It is also simple to distinguish between MT 56 series movement models. MT 5621 (calendar, dynamic display) MT 5612 (calendar) MT 5601 (no calendar, slightly smaller size) MT 5602 (without calendar) Flagship North Flag Drives Storage Display Using MT 5621 Movement The movement dismantled in this issue is the MT 5612, a basic large second hand with a calendar display. The movement was applied to many models of Tudor pedigrees, such as the Pelagos diving watch with the best sports watch award in GPHG in 2015, and the Jin Qicheng series launched in 2017. Blue plate Pelagos, waterproof depth up to 500 meters MT 5612 movement frequency 4 Hz, diameter of 31.8mm, similar to the Rolex 3135, also has overbearing, precision, resistance to operation characteristics. After opening the cover After opening the rear cover, it can be found that the two-piece cover plate below the balance-type bridge bridge plate and the balance wheel is of a ladder type design, and the whole gives a firm and stable feeling. Close-up view of ladder bridge Below the balance wheel bridge is a four-arm ring balance wheel with four screws to fine-tune the speed. This is a high-precision fine-tuning method, also known as no-calcino balance or inertial fine balance. The pendulum bridge plate can be removed to find the fine-tuning mechanism of the pendulum core: by finely adjusting a screw at the lower right of the balance wheel, the clearance of the pendulum core can be adjusted to make the travel time more accurate. After removing the balance bridge plate, there is a screw at the bottom right. This design is the same as Rolex Prince's 7040, 3035 is also one, and 3135 is two, that is, the pendulum fine-tuning mechanism functions when the balance shaft core is slightly worn. After fine-tuning the spacing, it still retains the precision of travel time. This design is rare in premium brands. At the same time, the silicon single-layer hairspring also protects the movement from magnetic fields and temperature differences. Balanced bridge plate detail removed, good seismic performance The MT 5612 uses Incabloc shock absorbers, not Rolex's KIF (the Rolex 3113, 3135, 3555, 3186 uses KIF shock absorbers, and the 3132, 3136, 3156, 3187, 9001 and other movements use Paraflex shock absorbers). However, because of MT 5612's large size, the shock absorber effect is still good, and the current PP and Lange are also widely used. The automatic disc is separated from the automatic winding mechanism, and the wheel train of the automatic winding mechanism is located on the side Rolex 3135's automatic disc is connected to the automatic mechanism, while the MT 5612 automatic disc is separate from the automatic winding mechanism and is automatically mounted on the wheel cover. The advantage is that it is not easy to break. This type of automatic winding mechanism is also relatively rare on the side of the wheel design, this design is generally to reduce the thickness of the movement. As for the arrangement of the wheel trains, there is not much difference between the general arrangements and the general design. Automatic swing 5612 is a two-way self-winding structure, ball bearings, good performance on the chain, dynamic storage for 70 hours, in line with the R & D trend of the new movement in recent years. The MT 5612 movement is basically a matte blasting process on the polished surface. It seems that there is a slight gap between the watchmates who used the Rolex movement. However, if you look at other brands with the same positioning, Tudor has done a good enough job, and it is hard to blame. Flicking: If we can deal with the pry box below the balance wheel, it should be perfect. MT 5612 is certified by the Swiss Observatory. In fact, it is not difficult to achieve COSC certification. In the course of R&D, the brand uses a computer to simulate all the possible conditions of the movement within 15 years and improve it against the defects. Adhere to quality. Of course, MT 5612 is also faced with short-term repairs, which is a special case. Mechanical watches cannot be 100% stable, and even bigger brands occasionally have a situation. The emphasis is on how to deal with the problems and learn from the problems. This is a problem that all brands should think together.
