The company is aptly named Montre Exacte, which is French for the highly precise watch. As early as his childhood days, Umscheid was fascinated by the fact that the different hands of the clock seemingly lead individual lives while inescapably pursuing a pre-set choreography. This master watchmaker learned his craft the traditional way at the vocational training college for clock and watch makers at Karlstein. Like Poysdorf, it is in the north of Austria, but slightly further west, where granite boulders are hard, water is soft and they have been manufacturing clocks for several centuries. Following stints in watch retail and wholesale, Umscheid ran a little shop restoring watches through the 1990s. It was there in 1999 that he was discovered by a Swiss maker of upscale watches, for whom he worked for from 2001 to The quarter watch is a high-precision chronometer from. Its distinctive feature is the second hand that returns to the initial position after completing quarter cycles. A separate quarter hand indicates in which quarter minute the second hand is at the time. All images are renderings based on data from Solid Edge and are

2 Results (continued) Saved effort required for prototypes Achieved predictable quality Reduced customer complaints Motion of the second and quarter hands is controlled by the unique quarter jumper. Shaped like a champagne glass (in blue), it is visible through the glass bottom of the watch body. Solid Edge is extremely fast, and has an intuitive menu navigation that allows great freedom for creating new files and making modifications to parts as well as assembly environments. While typical watchmakers usually do not develop a great affinity for information technology, early in his career Umscheid started to work intensely with computeraided design (CAD). He took a step toward three-dimensional (3D) modeling in the 1990s by acquiring a Solid Edge software education license from Siemens PLM Software. Umscheid s decision to acquire a Solid Edge CAD system has proven to have a profound effect on his career. By using a CAD system, I was able to analyze problems not only through the magnifying glass, but on the computer model as well, says Umscheid. I quickly developed a habit of modeling and inspecting parts in the CAD system prior to production. With Solid Edge, we don t need to build any prototypes. We can verify functionality more exactly than with the real object, and we can implement modifications to individual components or the entire assembly much faster.

3 The complete clockwork is made of about 200 components and provides precise function exactly 48 hours or 86,400 seconds from winding. achieves the desired level of precision by verifying the interplay between all individual parts. Using synchronous technology, Solid Edge supports all necessary modifications. By attaining such precision, he won a contest for the restoration of valuable watches and colleagues gave him the nickname l exacte (the precise), which is used in the company name. Providing distinct features I have always been annoyed by the enormous lack of precision with which watches all the way up to the most expensive chronometers are traditionally devised, says Umscheid. The practice of approaching the desired result experimentally basically by trial and error has been appalling to me since I was 17. This is why in 2012, Umscheid laid the foundation for his own manufacturing company. No more than one year later, he presented his first series of models. These models represent the neighborhood that they are made in, the wine quarter. It is called that because it is a wine-growing region covering about one quarter of the federal province of Lower Austria. One quarter (of a liter) is also the size of the typical glass in which vintners and innkeepers serve the local wine. The brown clock face with embossed ridges resembles typical barn doors and the strap is made of gradl, the material used to make vintner aprons. The packaging is carved out of used wooden wine barrels. The distinctive feature of the wine quarter watch is the quarter jumper shaped like a champagne glass that is visible through the glass bottom. It makes the second hand jump back to its initial position every Synchronous technology enabled us to align the methods that we use when working on the computer model as well as the piece itself.

We can verify functionality more exactly than with the real object, and we can implement modifications to individual components or the entire assembly much faster. 15 seconds and the unique quarter hand indicates the current quarter of the minute. In this way, the manually wound-up wine quarter watch works for exactly 48 hours. When the 86,400th second has passed, the second hand stops in its initial position. Removing restrictions In the haute horologerie (expensive watchmaking) of today, hand sketches are no longer the dominant means of designing, says Umscheid. The problem with specific software for watch design is it puts numerous restrictions on watchmakers, particularly stipulating practically all of the processes with predefined functions. This frequently results in the integration of identical errors by multiple manufacturers. This kind of software also does not usually offer easy ways to extract data required in generating presentation material or even for machine programming. As a watchmaker rich in experience at the workbench but with no formal CAD training, Umscheid first had to get acquainted with the unfamiliar methodology still history-based at the time of the CAD tool as well as with its nearly unlimited degrees of freedom. He found that it emancipated him from the restrictions of the industry solution, and enabled him to generate high-quality drawings for part production. Functional verifications are performed within the environment of the surrounding clockwork. This helps prevent collisions.

5 Aligning methods In a clock unit with numerous parts geared into each other, collision prevention is as important as the right play between them, says Umscheid. With very little initializing effort, Solid Edge affords us with all the benefits of 3D modeling that makes fulfilling these criteria easy. Convinced of the merits of Solid Edge, the self-educated CAD user updates his system with every new release of the Siemens PLM Software solution. In 2008, even before any users in mechanical engineering adopted it, Umscheid was the first customer in Austria who risked full conversion to synchronous technology, says Wolfgang Hackl, who has a CAD and computer-aided manufacturing (CAM) consulting company, and is a Siemens PLM Software channel partner. The unique synchronous technology for feature-based and history-independent modeling allows Umscheid to make changes to existing parts or assemblies with virtually no preparation. With Solid Edge providing a valid definition of dependencies, all affected parts are automatically modified accordingly due to the functions for direct modeling supported by live rules, which ensures the coherence of the entire time piece. A solution manager graphically visualizes all details of any changes during modification work. Synchronous technology enabled us to align the methods that we use when working on the computer model as well as the piece itself, says Umscheid. Solid Edge is extremely fast, and has an intuitive menu navigation that allows great freedom for creating new files and making modifications to parts as well as assembly environments. Of special importance for watch designers is that changes can be made as easily by entering new dimensions as by simply dragging the particular edge or face. we were able to create convincing presentation material using photorealistic renderings by using models from Solid Edge. They have a level of detail that can t be achieved with photos of the real object Presentation images directly derived from Solid Edge data show more detail than photos of the finished watch ever could, supporting timely sales success.

6 Solutions/Services Solid Edge Customer s primary business manufactures high-precision haute horlogerie watches in both classic and contemporary designs as well as instrumentation and custom design work. Customer location Poysdorf Austria Many months prior to the completion of the design work, we were able to create convincing presentation material with photorealistic renderings by using models from Solid Edge. They have a level of detail that can t be achieved with photos of the real object and come with the advantage that we can show certain functions of the watch in motion or in cross-section views. Eliminating prototypes Beyond the simple design, using Solid Edge offers the watch manufacturer far-reaching functionality for converting product ideas to high-quality, practical luxury goods. The opportunity to create all required tools by 3D modeling using the engineering data of the work pieces accelerates manufacturing of specific tools due to reduced data entry and helps prevent inaccuracy in dimension transfer. Programming of the special-purpose machines for the production of all turned, milled or spark-eroded components for watches also uses the 3D models of commercially available tools as well as the component modeling data of Solid Edge. With consistent data, the Austrian watchmaker ensures coherence of all manufacturing processes and seamless integration of all modifications. Through seven iterations, Umscheid, who is clearly a perfectionist, examines not only the flawless function of the whole clockwork, but also the interaction of parts to achieve the best possible result: a watch that does not require restoration or maintenance and retains its unparalleled precision over the lifespan of its wearer. Achieving timely sales Development of the base model of a watch over several years can only be refinanced if sales roll in promptly. In this area, Montre Exacte also benefits from the opportunities resulting from the comprehensive development of the chronometers in Solid Edge. Many months prior to the completion of the design work, we were able to create convincing presentation material with photorealistic renderings by using models from Solid Edge, says Umscheid. They have a level of detail that can t be achieved with photos of the real object and come with the advantage that we can show certain functions of the watch in motion or in cross-section views. As a result, s first limited series was sold out even before the first watch was ever produced.
