Music and Time

How do you check the time when it can't be seen?

This is a big difficult in mainly two situations - when your far from the nearest clock, and when you don’t want or can’t iluminate it. Some years ago, people start moving to towns and working by schedule, turret clocks were a big help in the organization of the working day rithms, then at night when in the absence of a wrist watch, or light, the best way to know time was by counting the chimes of the grandfather, mantle, cuckoo or other clocks.

So having already machine chiming the time why not making it play music as well? Music boxes and clocks togther start being the main way of knowing time.

Key wounded clocks may have from one to three holes the first one is responsible to keep the hours, minutes and seconds moving, the second wounds the spring that powers the chiming mechanism, and the third, if there is one, wounds the music box.


The Mechanism its a simple idea, a spring thats wound by a key its connected to a set of gear that rotates a cylinder filled with strategically placed rivets, those rivets lift hammers that hit metal tubes. If the tubes have different length it’s possible to make the sound of different music notes. The rivets work like fingers and the hammers like piano keys.

Some high-end wristwatches are showcases of technology and craftsmanship, but others try to throw a bit of fun into the mix as well.

One example is the Jacob & Co Opera watch, which ditches conventional chimes in favor of a complete 120-note music box that plays on demand.

And if that isn't enough, the mechanism rotates around the dial in a tiny ballet as it plays.
