JACOB & CO.

Jacob & Co. is known for a number of signature watch styles, such as the "Five Time Zone Watch," which it debuted in 2002. Inspired by the jet-set lifestyle of many of its clients, the timepiece features four fixed time zones—New York, LA, Tokyo and Paris—with the fifth dial set to the location of the wearer. Other notable watches include the "Quenttin," the first-ever watch with a 31-day power reserve, seven mainspring barrels, and a vertical, side mounted tourbillon (a regulating device in which the timekeeping element of the watch rotates inside a metal cage to negate the effects of gravity on accuracy), and the Ghost Watch, a Swiss made digital watch that features a pentagram shape and can display up to 20 time zones.
