Following the company relocation to Detroit, the Packard brothers focused on making automotive electrical systems via the Packard Electric Company. General Motors acquired the company in 1932, renaming it Delphi Packard Electric Systems in 1995. The company was spun off and became independent of GM in 1999.
In 1927, Packard commissioned the world's most complicated watch but not to be outdone, Henry Graves Jr. surpassed his rival in 1933 to become the owner of the most complicated watch ever made, spending 60,000 SF, nearly five times the price paid by Mr. Packard. It took over three years, and the most advanced horological technique in engineering this truly one-of-a-kind timepiece; only one watch was ever built. Complications included a perpetual calendar with phases and age of the moon, indication of sunrise and sunset, and a celestial chart depicting the constellations of stars in the sky over Packard's home in Ohio. Called "the Supercomplication" and designed and built by Patek Philippe, an ultra-complicated (with 24 functions) pocket-watch for Henry Graves, Jr. who entered into a friendly horological competition with James Ward Packard, which resulted in the production of the watch (known as "The Supercomplication") sold to Mr. Graves in 1933. This pocket watch, "the Supercomplication" was held in the Museum of Time near Chicago, IL for years until it was sold at Sotheby's for a record breaking  $11,002,500 to a secretive anonymous in New York City on December 2, 1999.

Before that he had experimented with electrical devices and organized two companies to manufacture them. In 1893, having studied the motor plans of Daimler and Benz and the body-building methods of Levasseur, he had drawn the plans for the first Packard; the financial depression of the next few years prevented him from manufacturing cars for the several years afterward. It was not until 1899 that the first Packard rolled out upon the roads, a high, sloping car, followed by children and stared at by scornful farmers. ..."
