Unique functions needle Seconds In Hours

 

Wall clocks or watches will usually consist of 3 types of needles, which is the shortest needle is pointing hour, minute needle and the needle is the most slender pointer seconds. At no clock watches that do not have a second hand. Well, after having hours that do not have a pointer seconds I just know this is a unique function of the second hand on the clock. Want to know what does it do? Ok, I'll tell ya tomorrow ... hahahahahaha .. joking .. Come on let's look below:
The second hand (which is shown above in red) has a very important function. This needle is a needle that we can see movement very well. Needles hours and minutes rather hard to see when it moves. The movement can be seen well is what makes it unique, why? Because when the second hand is not moving so we know what time it is dead.
That's right, right? So when the second hand has stopped, meaning our clock battery may need to be replaced or damage did occur in it. Clearly, the dead hours when the second hand is not moving.
