History of Quartz Watches
The first quartz clock was developed in 1927 by Marrison and Horton, who worked for Bell. It wasn't until the 1950s that this technology was compressed into a wristwatch.
The first quartz wristwatch wasn't actually a quartz watch as we know it today, but rather an electric watch made by Hamilton. It wasn't until 1969 that Seiko released the Astron 35 SQ, a watch that was incredibly accurate and priced at over £10,000 in today's money.
The Astron 35 SQ was a game-changer, and its release led to the development of "Super Quartzes" by top manufacturers like Breitling and Omega. These watches were phenomenally accurate and shielded against extreme temperatures and radiation.

A Brief History
The first quartz clock was developed in 1927 by Marrison and Horton, who worked for Bell. They were the pioneers of quartz technology.
In the 1950s, this technology was compressed into a wristwatch, but it wasn't the quartz technology we know today. Hamilton produced the first electric watch, but it wasn't a quartz watch like the Astron.
Seiko released the Astron 35 SQ in 1969, which was a highly accurate watch that cost over £10,000 in today's money. It was priced out of reach for many people.
The Astron has been unfairly blamed for almost destroying the Swiss watch industry. This claim is still debated today.
In 2023, quartz watches can cost anywhere from a few pounds to several thousand pounds, with all modules doing the same job.

Before
Before the invention of quartz watches, timekeeping was a labor-intensive process. Mechanical watches relied on intricate mechanisms and precise craftsmanship.
The first mechanical watches were developed in the 16th century, with keyless winding and stem setting emerging by the 19th century. These early timepieces were prone to errors and required regular adjustments.
In the early 20th century, the introduction of the first wristwatches made timekeeping more accessible and convenient. However, these early wristwatches were still prone to mechanical errors and required frequent adjustments.
The accuracy of mechanical watches was limited, with some watches losing or gaining up to 10 minutes per day. This lack of precision made mechanical watches less reliable for everyday use.

How Quartz Watches Work
Quartz watches are a clever combination of a battery, an integrated circuit, and a quartz crystal.
The battery releases an electrical charge that passes through the integrated circuit to the quartz crystal, causing it to vibrate up to 32,000 times per second.
The oscillation frequency is fed back through the integrated circuit, generating a precise electrical impulse that moves the hands accurately.
A quartz movement consists of a battery, electronic circuits, and a quartz crystal.
The battery sends electric current through the quartz crystal, causing it to oscillate at a frequency of 32,768 kHz.
The oscillations are measured by the circuits and converted into an exact time signal, which regulates the movement of the watch hands.
Quartz crystals are shaped like tuning forks and are incredibly precise, allowing for accurate timekeeping.
The quartz crystal's oscillation frequency is a key component of a quartz watch's accuracy.
Performance and Accuracy
Quartz watches are super accurate, delivering an accuracy of around +/- 20 seconds per month. This is a significant improvement over mechanical watches.
The 9F quartz movement takes precision control to the next level with a regulation switch that allows owners to adjust for any deviations in accuracy. This feature ensures the watch remains accurate even in extreme temperatures or other conditions.
A quartz watch represents a remarkable blend of precision, affordability, and durability, offering unparalleled accuracy compared to mechanical watches. By harnessing the consistent oscillations of a quartz crystal, quartz watch movements provide accuracy that's hard to match.
