How long does it take for the second hand of a watch to move 1 micron?

The second hand makes one full revolution in 60 seconds. The distance travelled by the tip depends on the length of the second hand - this is the radius of the circle. For example, for a 10-centimeter second-hand (the clock has a diameter of about 20 centimeters - that's a clock like you would typically see on a wall), the speed of the second-hand's tip is (2 x pi x radius) / 60 seconds = 2 x 3.14 x 10 / 60 or about 1.05 cm/second.

How many times does the long hand go around an hour?
We're assuming that you mean the "hands" on a clock.

What do the numbers around the face of a watch mean?
The numbers around the face of a watch indicate the hour and minutes of time depending on which hands of the watch are pointing to which numbers. The short hand points to hours and the long hand points to minutes. If the long hand is pointing to 6 and the short hand is pointing to 3 = 3:30 If the short hand is pointing to 6 and the long hand is pointing to 3 = 6:15
Compare 20 micron thickness to gold filled?
The thickness of gold on a gold-filled watch varies, including on the same watch, as a gold-filled finish can vary in thickness. But generally, a gold-filled finish will be about 20-40 microns thick. A 20 micron gold-plate finish is a bit thinner than most filled-gold finishes but is more uniform. A 20 micron gold-plate finish will wear a long time and compares well with a gold-filled finish.

How do you use a chronograph?
Hold the watch in one hand with the watch face toward you. The "crown" is on the right side of the watch between two buttons. A crown is a raised button. Pinch the middle crown with your fingers and pull it out as far as it will go. Turn the crown to set the time; the watch hands that originate in the center of the dial display the daily time. Push the middle crown in one stop so it is in the middle position between being flush with the watch and in the position you set the time from. You will see the date and day change on the left-side indicator on the face of your watch. Turn it forward to change the day; turn it backward to change the date. Push the crown flush to the watch case and use the crown in this position to wind the watch Start the chronograph by pushing the upper button on the right side of the case. This will activate the "second" hand, which is the long hand coming off the hour and minute hands at the center of the watch face. The second hand automatically starts the minute "totalizer," which is located below the date and time dial. The minute totalizer automatically triggers the hour totalizer, which is the dial at the bottom of the watch face. Stop your chronograph by pressing the bottom button once. To reset the totalizers and the second hand, press the bottom button again
