integrated pushers. Watches are still a main business of Porsche Design. In 1996 the Swiss watchmaker Eterna, which invented the ball bearing for the winding rotor used in automatic movements, was bought by F.A. holding company. The Porsche Design product suffering most often from plagiarism is probably the sunglasses with drop-shaped lenses, which was issued during the 1980s in a lot of unusual color combinations, e.g., purple lenses with golden or white frame. F.A. designed many more spectacles. Most often, they had some unique attributes — e.g., a saddle-shaped cushion adapting to the nose shape automatically and opening symmetrically through an internal cam mechanism. The drop-shaped spectacle had a quick release mechanism to provide quick lens changes. One pair even had magnetically held lenses; another one got its shape from the intended production method: Its shape was accommodated to a sand casting process of titanium. The production issue was actually not made of titanium, but the shape remained. Transportation design remained an issue on F.A. Porsche. He made several studies for metropolitan trains, a motorcycle, several bicycles and a slightly dolphin-shaped racing boat called Kineo. As the company grew the product categories diversified. There are three possibilities how designs made by Porsche Design can appear — Porsche Design brand products made exclusively for Porsche Design; products bearing the manufacturer's name and the writing "Design by F.A. Porsche"; and products with no hint of Porsche Design at all. Porsche Design came up with several bathroom designs, a washing machine, furniture, knives, television receivers, desk lamps (one with three telescoping radio antennas attaching the light bulb holder to the base and one employing design aspects of a guillotine in its pull-out mechanism), tobacco pipes with air-cooled-engine-inspired cooling fins, pens made out of wire-cloth used in oil hoses for racing engines, computer monitors, computer external hard drives, coffee makers, and even a grand piano for an Austrian manufacturer Bösendorfer. The Design by F.A. Porsche mark is used no more, with the exception of the professional kitchen knives of Chroma Cnife. The formerly completely private owned Porsche Design company belongs in the meantime to a cooperation company between F.A. Porsche and the Dr.-Ing. hc F. Porsche AG, of which F.A. held roughly 13%. F.A. Porsche retired in 2005 due to his state of health. He was given the title Honorary Chairman of the Supervisory Board, a title that was originally invented for his father
