Whether you’re looking for yourself or browsing gifts for loved ones, a watch is always a great option for convenience as well as style. How do watches work? Time-keeping devices are ingenious in design, not to mention elegant.
The first wearable watches included the mechanical watch, famed for its ‘ticking’ sound. Mechanical watches utilise a series of compartments that operate in harmony with one another. The first is the mainspring, which measures the passage of time and needs to be wound every so often.
A weighted compartment called a balance wheel moves back and forth, and with each turn of the balance wheel an escapement allows the wheel to move forward, allowing the hands of the watch to move ‘clockwise’ at a consistent pace. Due to their delicate nature, these kinds of watches require periodic specialist cleaning. In the 1920’s, the use of electricity provided an entryway into a new era of watchmaking. An electronic oscillator is controlled by a quartz crystal, eliminating the necessity for the winding process of the mechanical watch.
This highly sophisticated technology became commonplace by the 1980’s, as the materials are inexpensive and able to be mass-produced. This style of watch now dominates the watch market, as it is able to produce more precise timekeeping and requires less maintenance than its predecessor.
