Patek Philippe's "advanced technology research" series wonderfully launched a new timepiece, Ref. 5750 three question clock, equipped with a special fortissimo sound amplification and transmission system, which opened a new chapter for the timepiece.The fortissimo "FF" component consists of an elastic interruption sound rod and a good oscillating wafer made of see-thorugh sapphire crystal. No matter what kind of material the case is made of, the device can make the sound clearer as well as louder, and the sound quality is superior, which is far better than the traditional 3 question watch. This special edition chronometer features a smooth case and a great arc ring. The design is actually inspired by the ref. 5178 three time reporting watch equipped with "church bell" audio spring. The case is 40mm in height and 11. 1mM in thickness, which is 0. 57mm thicker than the ref. 5178 view. In order to show the excellent performance of fortissimo system, Patek Philippe specially selects 950 platinum material with poor sound transmission effect. It has achieved an innovative breakthrough in the manufacturing technology of timekeeping watches. The dial design is ingenious and consists of five parts. The central part will be decorated with a hollow pattern, which is inspired by the spokes of antique cars. The actual black bottom is decorated with spiral lines of cochlear design to make the hollowed out pattern more eye-catching. The small second hand watch dial is located at 6 o'clock position and also adopts a rotating dial with the same hollow routine and black cochlear background; In addition , there is a small mobile indication mark to add another flexible atmosphere. The switch is equipped with the platinum sword shaped flat pointer and a black Zheng Plated American platinum eagle three-dimensional period scale to really make the time display clear at a glance. Patek Philippe's three question time reporting watch provides you with R 27 automatic gathering movement, that is shining back. The technicians and designers who devote themselves to Patek Philippe's "advanced technologies research" depend on the famous movement, strive to improve the time volume through mechanical devices, ensure excellent sound quality, and minimize the size of the movement. After technical exploration in multiple directions, they decided to offer the design of the basic movement, Then on one side of the splint A element (facing the actual wrist side) is added as a mechanised loudspeaker. Generally, the loudspeaker relies on a phalic shaped diaphragm, which can be connected to the external edge like a drum skin. The Patek Philippe loudspeaker system does not use a diaphragm, but uses a 0. 2mm thick artificial sapphire oscillating wafer. This wafer is hard and can move freely. Through the angular motion of the wafer, the device can Greatly enhance the sound transmitting effect between the square inches of the enjoy. Three patents have been registered for this public address program. Transparent blue glass chip can also ensure that the details of the movement can be seen at a glance. The roll-out of this miniature public address system is full of challenges, which makes the design along with manufacture from the movement face a severe test.
