It's actually pretty simple!
There should be 4 buttons on your digital watch otherwise it may not work: Mode, Light, Start/Stop, Set.
1st. Click SET
2nd. Click both SET & MODE
If it doesn't work that instant, try clicking both SET & MODE a few more times.
And it should work the other way around, to change your digital watch from 12 hour to 24 hour.

Analog clocks have an hour hand and minute hand, and 12 numbers around a circle.
10:10, 11:11, 12:12 = 3/12 = 1/4 = 25% of the time.
10 past four in digital time may be written 4:10 if using a 12 hour format. When using a 24 hour format, it may be 04:10 if it is in the morning or 16:10 if it is in the afternoon.
If it is a 12 hour clock then on 9 pm on the Tuesday of the sixth week they will both be correct.

Chronographs/stopwatches are only made to time a certain limit. For digital watches, it can be up to as many digits as the digital watch can display, or limited by the manufacturer. For analog watches, it's only as far as the complexity of the mechanism. Some examples of analog watch chronograph limits can be 30 minutes, 1 hour, 12 hours, or even 24 hours.
On a digital 12 hour clock system it is shown as 07:20On a digital 24 hour clock system it is shown as 19:20

If you point the hour hand of a 12 hour watch in the direction of the sun, a point half way between the hour hand and the shortest distance to the 12 will be South in the Northern Hemisphere. If you are in the Southern Hemisphere, switch the hour hand and the 12 in the above directions and you will be pointing to the North. Of course, this is only a rough guage and is less accurate the closer you are to the Poles or the Equator. Don't forget to set your watch for the correct time zone.

Using your wrist watch you can find north within about 10 or 15 degrees. It's real easy... Step 2 You need a watch that has hands on it. A digital watch won't work here. Step 3 To find north using your watch, you will only be concerned with the hour hand and the number 12 (or the 1 if it is daylight savings time in your area) on the watch. Disregard the minute hand. Step 4 There are a couple basic rules to follow.... Step 5 If it is MORNING (AM), wait for the sun to rise. Point the hour hand of the watch in the direction of the sun (keeping your watch level to the ground) .... Step 6 Split the difference between the 12 and the hour hand on the LEFT side of the watch. (If you area is experiencing daylight savings time, split the difference between the 1 and the hour hand) .... Step 7 Here's an example of using the 12 and the hour hand. Say it is 8:00 am. Point the hour hand in the direction of the sun (keep the watch level). Splitting the difference between the hour hand (8) and the number 12, you'll find that north is in the direction of the 10. (See the thin black line on the photo. This is pointing north. Also notice the time on the watch shown is actually a little before 8:00 pm. That's fine, concentrate ALWAYS on the hour hand :-) Step 8 If it is in the AFTERNOON, the rules change and you want to use the RIGHT side of the watch. Say around 4:00 pm for example, you want to split the difference between the number 12 and the 4. Notice the thin black line in the photo goes to the right side of the watch. North would be in the direction of the 2. (Also notice the time on the watch is actually a little after 4:00 pm. That's fine, concentrate ALWAYS on where the hour hand is ;-) Step 9 Third rule.. if it is EARLY EVENING, split the difference between the hour hand and the 12 using the RIGHT side of the watch (like the 'afternoon' rule)... Step 10 For example at 8:00 pm EARLY EVENING, split the difference between the 8 and the 12 and north will be in the direction of the 4. Notice the thin black line points toward the 4. (Notice the time on the watch is actually a little before 8:00 pm. That's fine, concentrate ALWAYS on the hour hand, disregard the minute hand :-) Step 11 Keep in mind that if you area is experiencing daylight savings time split the difference between the hour hand and 1 on your watch using the rules above.
