Portable precision clock with additonal functions
First Claim
1. A portable precision watch with time-keeping functions, additional functions and energy storage means, wherein the watch also containsa GPS receiver with an antenna and evaluation electronics,a compass for determining the magnetic north-south direction,a memory for storing destination coordinates,an input element for inputting selectable destination coordinates,and a display element for displaying the direction from a location to a destination, whereinwith the evaluation electronics, the coordinates of the location are determined andfrom the coordinates of the location and the coordinates of the destination, the direction to the destination is calculated,wherein by way of the compass the alignment of the watch to the geographical north-south direction is determined and taking account of this alignment of the watch, the direction to the destination is made viewable as a vector display in the display element,wherein all elements are grouped together as a compact functional unit and the computation of the data is effected in a microprocessorand wherein the watch time can be controlled by the received GPS time.

Abstract
The portable precision watch, additionally to time-keeping functions, also comprises a GPS receiver with antenna, evaluation electronics, a compass, a destination coordinate memory, an input element and a display element. With the evaluation electronics the coordinates of the location and the direction to the destination are computed and are made directly viewable as a vector display in the display element. Thus a very compact precision watch is provided which may be personally carried everywhere and worldwide, and directly displays the direction to any destination, in particular as a pocket watch or wrist watch.
