Two column wheels control the chronograph functions. One of them deflects the arms of the rattrapante splitseconds clamp. The clamp is freely suspended so that its arms can centre themselves around the periphery of the rattrapante wheel, gripping it with uniform pressure from both sides. The surfaces of the clamp and the wheel are finished with straight and circular graining. The fine teeth of the wheel are roughened for a better grip.<\/p>", "ShareDescription" : null, "ShareLink" : "https:\/\/www.alange-soehne.com\/-\/J3wpXhr", "ImageURL" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/SetWidth1680-170725-Tourb-gallery-1.jpg", "ImageTitle" : "170725 Tourb gallery 1", "MobileImageURL" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/CroppedImage760428-SetHeight428-170725-Tourb-gallery-1.jpg", "Width" : 960, "Height" : 560, "ThumbLink" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/CroppedImage200125-170725-Tourb-gallery-1.jpg", "ThumbList" : [], "ExpertInfos" : false, "Videos" : false, "MediaCategory" : "Bild", "OneColumnText" : "0", "ZoomImageURL" : null, "ZoomImageTitle" : null, "IframeURL" : null, "ID" : 7583 }, { "ClassName" : "Media", "Title" : "Assembly of the perpetual calendar and the moon phase", "Description" : "
The perpetual calendar correctly displays the different durations of the months in the 100-year cycle of the Gregorian calendar. In other words, it only needs to be corrected by one day in the year 2100. This is ensured by the 48-month wheel of the calendar module that has recesses and protrusions for each month.<\/p>\n
The seven-stage transmission for the moon phases is calculated so precisely that it only needs a one-day correc-tion after 122.6 years of uninterrupted operation. The deep blue hue of the white-gold lunar disc is the result of a patented coating process. Interference effects function like a filter that hides all non-blue colour spectra of the incident daylight. The crisply contoured stars are cut out of the coating with a laser beam.<\/p>\n

Assembling the tourbillon is one of the most difficult tasks in crafting the TOURBOGRAPH PERPETUAL \u201cPour le M\u00e9rite\u201d. Before the filigreed component can be positioned in the basic movement, it will already have undergone a multitude of preparatory steps. The long road to perfection begins with the preliminary assembly of individual parts. Initial assembly is followed by adjustments, disassembly, final finissage and final assembly. The tourbil-lon bridge firmly secures the cage to the chronograph bridge as it rotates suspended between two diamond end-stones. The newly introduced curved shape of the tourbillon bridge posed new challenges to the finishing special-ists. The black-polish technique applied to the surface of the steel part is finished to a mirror gloss so immacu-lately that incident light is reflected in only one direction. The surface shines only when viewed from that angle. From all other perspectives, it appears to be jet black.<\/p>", "ShareDescription" : null, "ShareLink" : "https:\/\/www.alange-soehne.com\/-\/ldwBXJr", "ImageURL" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/SetWidth1680-170725-Tourb-gallery-3.jpg", "ImageTitle" : "170725 Tourb gallery 3", "MobileImageURL" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/CroppedImage760428-SetHeight428-170725-Tourb-gallery-3.jpg", "Width" : 960, "Height" : 560, "ThumbLink" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/CroppedImage200125-170725-Tourb-gallery-3.jpg", "ThumbList" : [], "ExpertInfos" : false, "Videos" : false, "MediaCategory" : "Bild", "OneColumnText" : "0", "ZoomImageURL" : null, "ZoomImageTitle" : null, "IframeURL" : null, "ID" : 7587 }, { "ClassName" : "Media", "Title" : "Assembly of the rattrapante wheel", "Description" : "
The rattrapante hand arbor is about one centimetre long and extends from the dial to the rattrapante wheel on the opposite side of the movement. The arbor is turned from one piece of round hardened steel and painstakingly trued by hand. Then, it is passed through the hollow chronograph hand arbor.<\/p>", "ShareDescription" : null, "ShareLink" : "https:\/\/www.alange-soehne.com\/-\/GywCXJr", "ImageURL" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/SetWidth1680-170725-Tourb-gallery-4.jpg", "ImageTitle" : "170725 Tourb gallery 4", "MobileImageURL" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/CroppedImage760428-SetHeight428-170725-Tourb-gallery-4.jpg", "Width" : 960, "Height" : 560, "ThumbLink" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/CroppedImage200125-170725-Tourb-gallery-4.jpg", "ThumbList" : [], "ExpertInfos" : false, "Videos" : false, "MediaCategory" : "Bild", "OneColumnText" : "0", "ZoomImageURL" : null, "ZoomImageTitle" : null, "IframeURL" : null, "ID" : 7589 }, { "ClassName" : "Media", "Title" : "Assembly of the fus\u00e9e-and-chain mechanism", "Description" : "
Once the watchmaker has wrapped the delicate chain around the previously assembled mainspring barrel, they can integrate both components into the basic movement. The chain is then attached to the fus\u00e9e. The planetary gearing or differential must be mounted first. Inside the fus\u00e9e, it ensures that the flow of power from the main-spring barrel to the escapement is not interrupted while the watch is being wound. The 38-part mechanism handles this function in a space with a diameter of merely 8.6 millimetres.<\/p>", "ShareDescription" : null, "ShareLink" : "https:\/\/www.alange-soehne.com\/-\/61w2X6r", "ImageURL" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/SetWidth1680-170725-Tourb-gallery-5.jpg", "ImageTitle" : "170725 Tourb gallery 5", "MobileImageURL" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/CroppedImage760428-SetHeight428-170725-Tourb-gallery-5.jpg", "Width" : 960, "Height" : 560, "ThumbLink" : "https:\/\/www.alange-soehne.com\/assets\/GalleryImage-2880x1800-px\/_resampled\/CroppedImage200125-170725-Tourb-gallery-5.jpg", "ThumbList" : [], "ExpertInfos" : false, "Videos" : false, "MediaCategory" : "Bild", "OneColumnText" : "0", "ZoomImageURL" : null, "ZoomImageTitle" : null, "IframeURL" : null, "ID" : 7591 } ] , "ID" : 8261 }
