Method 1: Divide the current time by 2 and point the resulting quotient at the sun. The direction to which 12 on the dial points is north. For example, if it is 8 a.m., divide by 2 and the quotient is 4. Align the 4 on the dial with the sun, and the direction 12 is facing is north. If it is afternoon, the calculation should be done in 24-hour timekeeping.
Method 2: In the northern hemisphere, place the watch horizontally, with the hour hand pointing to the sun, and the bisector of the angle between the hour hand and the 12 o'clock scale pointing in the north-south direction.
Note: To determine the direction with the above methods, the exact local time must be used, such as the local time in Urumqi is Beijing time minus 2 hours and 9 minutes; in addition, these methods cannot be used south of the Tropic of Cancer because the closer you get to the equator, the sunlight is almost direct, and it is difficult to use a watch to discern the direction.

How do you recognize direction with watch hands?
With the hands of the watch to identify the direction: Method 1: the time divided by 2, the number of the hands aligned with the direction of the sun, then 12 o'clock in the direction of the north. For example, four o'clock in the afternoon, that is, 16 o'clock, divided by 2 to get 8, the position of the 8 o'clock against the direction of the sun, then the direction of 12 is north. Method 2: (Northern Hemisphere) Place the watch flat, the hour hand points to the sun, and the direction of the reverse extension of the hour hand and the 12 o'clock degree equidistant line is north. (Southern Hemisphere) The direction of the 12-hour degree aligned with the direction of the sun, the direction of the center line of the angle between the 12-hour degree and the hour hand is due south, and the reverse extension is due north. Extended information on other ways to identify the direction after getting lost 1, shadow clock method: on a flat piece of ground, placed 1 meter long vertical tree trunk. Note the location of the tree's shadow, and mark the top with a stone or stick. 15 minutes later, mark the new projected location of the top of the trunk on the ground. The line between the two points will give you the east-west direction - mark west first. 2、Make a simple compass: In the absence of the sun, you can use a small piece of wire to magnetize it by rubbing it sufficiently against your own hair, then place it on a leaf, then let the leaf float in still water, and the magnetized wire will cause the leaf to rotate slowly until it is aligned in the north-south direction, and then you can use other methods to identify the specific direction. A piece of wire (or a sewing needle) rubbed repeatedly in the same direction against the silk will become magnetic and can be hung to indicate the North Pole. The magnetism will not be very strong and will need to be re-fricted at intervals to increase the magnetism. If you have a magnet, it will be more effective than using the silk - be careful to keep rubbing the iron needle against the magnet in the same direction. Suspend the magnetic needle from a piece of string so that it does not interfere with the balance. But don't use a cord that has kinks or twists in it. 3, the scientific use of the North Pointer: When the magnetic needle of the North Pointer is stationary, its N end (usually have a sign) pointed in the direction of the North. The use of the compass to identify the direction is very simple and fast, but need to pay attention to: 1. Try to keep the compass level; 2. Do not distance from the iron, magnetic material is too close; 3. Do not mistake the S end of the magnetic needle as the north, resulting in 180 ° of the direction of the miscalculation. 4, with the eyes of the pie: 1) observation of the sky: observation of the sky is the most common observation of the North Star, the night, in the dark starry night sky, we will always find the shape of a spoon of the Big Dipper, the end of the spoon at seven times the distance of a bright star, that is, the North Star, which is directly under the North, clockwise that is, East, South, West. 2) Observe the Sun: Every day the sun rises in the east and sets in the west - but not due east and due west either. There are some seasonal deviations; when the sun is at its highest point at noon, in the Northern Hemisphere, it is located due south; in the Southern Hemisphere, due north. The distinction between the northern and southern hemispheres can be determined by the movement of tree shadows: clockwise in the northern hemisphere and counterclockwise in the southern hemisphere. Tree shadows can be used to determine both direction and time. 3) Observation of trees: you can find a tree stump to observe, the broad side of the annual cycle is the south; or to find a tree, its south side of the branches and leaves of the north side of the sparse. 4) Observation of rocks: where there are many rocks, you can also find a striking rock to observe, the moss-covered side of the rock is the north side, the dry and bare side is the south side;
