The beginnings


Del West was founded in 1973 near Los Angeles by Al Sommer, an aerospace engineer. The company is now a world leader in valve train components for high-performance engines. Having dominated the Formula 1 circuits for over 30 years, we are also renowned players in the aerospace, medical device and luxury markets. Since 2008, we have been a recognised player in the Swiss watchmaking industry. Amassing a unique combination of skills, the Swiss Del West structure combines materials science and cutting-edge skills in industrial creation and production. All of our watch activities are centralised in Roche, in the Swiss canton of Vaud.

Olivier Conne

Chief Executive Officer


With his unwavering optimism, entrepreneurial spirit and a strong tendency to stray from the beaten path, he could have easily been “born in the USA”. But he is Swiss, trained at EPFL before earning his stripes at a large multinational for which he worked on four continents. His go-getting attitude hinges on the precision, rigour and deep-set demand for honesty that characterise his Swiss roots.

Born to innovate

At Del West, everything begins in the same way: discovering new solutions and developing unique concepts to answer the questions of tomorrow. Incorporating a design office, watchmaking workshops, cutting-edge simulation tools and production on the same site, Del West is a well-oiled machine destined to invent and create for you. And although we have been creating innovative watches since 2008, we have known how to do so for much, much longer: pioneers of titanium valves and inventors of ceramic coatings for pneumatic valve springs, we have been at the cutting edge of motor sport innovation for over 30 years.

World firsts created by Del West

Del West creates all-new materials to produce extraordinary watches. Here are a few examples of innovations developed and produced for watch brands with exacting standards.

We created the world’s first watch made from PEO Coated aluminium. This all-new composition combines the lightness of aeronautical aluminium with the unique hardness and appearance of ceramic.

Even more lightweight than aluminium, we produced the very first PEO Coated magnesium watch. This material also offers a technical white colour with a unique look.

For an MMC (Metal Matrix Composites) watch, we directly incorporated ceramic into the material – a first in watchmaking. The ceramic microspheres are introduced into the very structure of the aluminium matrix. The watch is also covered with ceramic to protect it.

To create the very first watch made from TiAl intermetallic, we succeeded in giving this material the intended shape even though it is renowned as being impossible to machine. The challenge was worth it: formed of equal parts aluminium and titanium, this metal is very light yet also very resistant to oxidation. This is an example of the cutting-edge skills developed by Del West for F1 and adapted to create an exceptional watch.

Design and industrialisation


At Del West, our employees frequently wonder: “What if…?” Often, an idea arises from this question, from a mixture of curiosity and imagination. Everything begins with an idea. But ideas also come from our clients. Working in the strictest confidentiality, our specialists interpret their requests and elucidate them. Now come the design tools. Once we have settled on an idea, we conceptualise various different options using CAD (Computer Aided Design) software such as CATIA or SolidWorks, which are industry standards. We then use FEM (Finite Element Method) software such as ANSYS or others developed in-house, to evaluate the behaviour of each option when confronted with different physical constraints. Lastly, we complete a number of successive iterations to be sure that we have settled on the perfect solution.

Quality


Precision is part of Del West’s signature, and that is no coincidence. It defines our organisation. We demand that our products are of the utmost quality because our history has made this requirement an essential element. Demonstrated by a true culture of high quality – crucial in the world of Formula 1 – the widely renowned precision of our products is ensured by the most advanced three-dimensional and optical measuring instruments. But it is also guaranteed by our valued employees – the watch parts are inspected by professionals with extensive experience in the watch industry. The visual assessment is carried out in accordance with the strictest requirements for watch aesthetics.

DLC and PVD


DLC (Diamond Like Carbon) coating is an extremely thin film applied using plasma-assisted chemical vapour deposition, or PACVD. These coatings combine a very low coefficient of friction with extreme hardness. They are used to reduce wear in a wide range of industrial applications and to make watch parts more attractive. Del West mainly makes use of them when reduction of friction is an essential objective, such as for watch movement components. Outside of its watchmaking applications, we have been using this coating for over 20 years in products intended for use in motor sports. Our “thin film coatings” service is provided by UB-TS, a joint venture created with our partner HEF and based at the Roche site.

PEO surface treatment

PEO surface treatment


Plasma electrolytic oxidation, or PEO, is a very dense and hard ceramic treatment applied to surfaces made from light alloys such as aluminium, titanium, magnesium or zirconium. We apply extremely hard treatments that have an average thickness of 30 microns. PEO differs from other surface treatments such as anodising due to its intrinsic adhesion to the substrate to which it is applied and its greater resistance to wear. It is also a lot denser. There are many applications of this treatment, which include the coatings of F1 pneumatic valve springs and certain watch components.
