In 1846, Ulysse Nardin founded what is now one of the world's premier makers of fine mechanical watches. Today, the name Ulysse Nardin is synonymous with elegance, quality, and innovation. Few products pack so much mechanical complexity into such a small area as fine watches. With more than 400 moving parts, Swiss watches, such as those made by Ulysse Nardin, have long been marvels of design and artistry. But in today's competitive marketplace, even companies like Ulysse Nardin must accelerate time to market while controlling costs. To make its product development process more efficient, the company implemented the Autodesk® solution for Digital Prototyping using Autodesk® Inventor®, Autodesk® Vault, and Autodesk® Showcase® software.

Prior to turning to Digital Prototyping, Ulysse Nardin spent about four years designing the inter¬nal mechanisms for each new watch it created. The process was lengthy due to design complexity, small design teams, and the number of physical prototypes required. Yet in the competitive market for high-end watches, Ulysse Nardin had to create ever more innovative watches—faster.

"Innovations take time and care to perfect," notes Pierre Gygax, Ulysse Nardin's executive vice president of production. "For example, with our perpetual calendar watches, you can adjust the date as you cross time zones with the push of a single button. The gears and springs inside do the rest. With 2D tools, designs took a long time, and then we still had to do three-to-five rounds of physical prototypes to achieve the high level of quality our customers expect."

Loïc Pellaton, Ulysse Nardin's technical manager, explains the challenge of 2D design further, "We used 2D design tools to draw the gears and springs, but we used our expertise and experience to mentally keep track of how all the parts would fit together. Only a few people could work on each design—it was simply too difficult to prevent interferences with multiple designers involved."

Ulysse Nardin accelerated its product development cycles using Autodesk Inventor software to cost-effectively take advantage of a Digital Prototyping workflow. As the foundation of the Autodesk solution for Digital Prototyping, Inventor software allows Ulysse Nardin's mechanical designers to create an accurate digital prototype of a new time piece.

Working with a 3D model, watch designers are able to visualize how gears and springs fit with other components as they design. This makes it much easier for them to spot and eliminate interferences early in the design process. They can also optimize the positions of mechanical parts that integrate with external portions of the watch, which are initially drawn in 2D by a conceptual designer.

"A typical Ulysse Nardin watch contains about 400 moving parts," says Pellaton. "Having a clear 3D view is a significant advantage. Autodesk Inventor helps us to place parts and explore different options very quickly. It has significantly accelerated one of the most complicated aspects of watch design."

More Effective Teams
With digital models integrating the design process, Ulysse Nardin has been able to use larger and more interchangeable design teams. These teams rely on Inventor to help them explore and hone digital prototypes, reducing the need to produce multiple rounds of physical prototypes.

"The digital prototype allows teams to easily validate their designs against the work of other teams," explains Gygax. "Designs progress more quickly and without collisions. With Digital Prototyping, our watch movements and cases are largely refined during design, so we produce just one physical prototype instead of three."

Streamlined Change Management
Ulysse Nardin uses Autodesk Vault to manage design data while making it easier for other workgroups to collaborate with the design team. So if people on the shop floor spot an opportunity to enhance a design, they generate a change order within Vault. The software automatically sends appropriate alerts and manages the change request.

"We are able to process change requests more effi¬ciently with Vault," says Pellaton. "It brings everyone who needs to review the request together electronically, allowing us to make changes quickly and with minimal disruption to other projects."

Finishing Touches
To help refine its watch cases, Ulysse Nardin recently began using Autodesk Showcase software. Autodesk Showcase creates accurate, photorealistic images of Ulysse Nardin's digital prototypes, enabling more efficient decision making. For example, the software allows design teams to visually explore a wide array of decorative and watchband options without having to produce a single physical prototype.

"We are impressed with Showcase," says Gygax. "It allows us to compare realistic representations of different watchband materials side by side. We see precisely how each band will complement the watch face. Product images created with Showcase are so realistic that we have used them instead of product photographs on our website."

Pellaton points to accelerated product development cycles as a key benefit of Digital Prototyping. He says, "With Inventor, we realize our vision twice as quickly. Instead of taking four years to design and produce a new watch movement, it now takes two. Inventor has also helped us lower costs. We are sav¬ing as much as $30,000 in prototyping production costs for each new watch movement."

Looking at the big picture, Gygax adds: "Inside and out, our customers expect a work of art. Autodesk Inventor provides an environment to explore ideas and continue innovation in the art of mechani¬cal watch making. From the beautiful case to the movement Ulysse Nardin watches are renowned for, Digital Prototyping helps us to create the kind of watches people dream of owning."
