Each pocket watch works in a similar way. Most often, the sphere is divided into 12 parts. Each of these 12 parts conform what is known as the "arc zone".
The passage of time and different historical events opened up the opportunity for new pocket watch models.
What it is and how it works?
Pretty strange for a pocket watch, its original function was not only tell time but also indicate astronomical times. Therefore, at first sight takes some time to know and understand what they represent current trademarks and designs in the quadrants.
One can distinguish three parts:
- At the top there are a couple of small windows that when opened reveal a dozen animated figures of wood, the apostles, who parade every time the clock shows a new time. At the center is a rooster that sings when the parade ends and the windows are closed. This parade of the apostles is what brings crowds, even a quarter of an hour before!
Functionality and watch angle
Are you familiar with the pocket watch functionality? You can easily learn how to calculate the angle. For an hour the hour hand travels the arc of 30 ° (i.e., every minute moves 30: 60 = 0.5 °). The minute hand goes 360 degrees in one hour (i.e. 6 degrees in a minute). Thus the path of the minute hand is 12 times greater than the hour hand. Consider the following guideline:
1 .- Use the numeric control the hours angle to see that the angle corresponding to a time zone displacement of the needle "arc zone" is 30 º.
2. - Use the numeric control the minutes angle to see that the angle corresponding to a minute shift of the minute hand is 6 °.
3. - Press the start button for the pocket watch to indicate the 12 o'clock. Use the numeric control to point to in the 12 hours and one minute. Note that the text of the scene (in yellow) indicates the angle that the needle is 5.5 °. As you have seen before the minute hand has moved 6 °.
4. - Press the start button for the watch to indicate the 12 o'clock. Use the numeric control put in hours to mark the 1 o'clock. How many times has been the route of the minute hand of the needle the schedule? The astronomical pocket watch located in the tower of the former Old Town Hall is one of the great attractions of the city. This old clock, which dates from the early fifteenth century, gathers crowds of visitors when the show each new time was set in motion a set of small robots.
