The Quartz Watch

Posted by Joel Bixi on

In the mid 1920’s, the discovery of the “crystal oscillator” paved the way for the now most popular Quartz watch. For informational purposes, the definition of “Quartz” is that, the accuracy of the watch is powered by a mineral crystal that has the same name. (In technical terms, when the crystal oscillator which is a quartz crystal cut in the shape of a tuning fork, comes under mechanical stress it creates voltage called “Piezoelectric” that makes it oscillate (vibrate) which creates a consistent frequency. In watches it is usually 32,768Hz, which is high enough so most people can’t hear it, but this frequency is picked up by an electronic counter that overflows once a second, thus sending a pulse once per second that drives the accuracy in clocks). Enough with the technical, back to watches… In 1927 the first Quartz clock was invented, and in 1967 the first Quartz watch prototype was revealed, it now represents most of the watches manufactured worldwide. 

This tuning fork is made out of Quartz Crystal - Actual size 3mm.

Paving the Way To Today's Watches

In the beginning of the 16th century, with the invention of the mainspring, a thin metal wire that gets wound up with a key, and keeps the wheels of the watch turning for hours until it’s due for the next wind, this innovation enabled longer time keeping per spring wind, as well as to create [...]

The Solution

The accuracy problem was so great that early clocks didn’t even have a minute hand. There was just an indicator on the dial, which was marked with 4 zones, indicating in which 15 minute zone one is. Some clocks of that era do feature a second’s hand, which is believed just to show that the [...]

The Evolution

Accuracy of time was a big issue (imagine walking to town square to check the sun dial, and suddenly it becomes over cast), so in the 15th century, with the invention of springs, innovators got to work to incorporate this new device into time pieces, namely big clocks that were kept moving while the spring [...]

History of Time

Until the 15th century the sun was the source of time from looking at its position in the sky, to elaborate sun dials in town square. As you can imagine meeting times couldn’t be too accurate, but then again, if one lived in a small town with limited outside contact, there was always time to [...]

The Watch Industry

There’s a nifty little device that makes our lives so much easier, it keeps us organized, tells us when to eat, when to sleep, when it’s time to go to work and when it’s time to leave work, when is our next appointment, interaction, meeting, connection, date etc. it’s a very integral part of our [...]

Introduction

I would like to write a little something about the evolution of time and it's devices, i'll keep it short and to the point, with just a bit of background information about the watch industry in general, and STORM concept and design in particular, so why don't you join me for the ride, and let's [...]
