Porsche Design’s new P 6520 Compass Watch comes in at 42mm and is inspired by their first Compass Watch from 1978. “The P 6520 Compass Watch comes in two parts: the upper part is a three-hand watch. The lower part of the watch opens to reveal a liquid compass that can be easily removed. The watch is available with a compass for both the Northern as well as the Southern hemisphere.” A scratch resistant mirror helps align you. Limited to 911 units. (Via Selectism).
