It might not be the first timepiece from Porsche Design, but the Porsche Design Timepiece No. 1 Watch is the first to be developed entirely in-house. Much like the company's first watch from 1972, the No. 1 is an all-black affair, with a 42mm titanium case that's treated instead of painted to make the matte finish more durable, as well as a black instrument dial with contrasting white markers. Behind the blackened sapphire crystal case back, a mechanical Valjoux 7750 chronograph mechanism keeps the time with a power reserve of 48 hours, and a black rubber strap rounds out the understated look. Limited to just 500 units worldwide.
