We are not born with a sense of “time”; however throughout the history of civilization a manifestation of order and an incredible interest in past, present and future seemed to create a need to measure our tasks and activities.
First, simply the measure of light and dark destined our lives.
The observation of the moon, the sun and stars, together with their movement helped measure the passing of time and enabled a little planning.
The Egyptians were probably the first to divide daylight into twelve equal parts however, as the length of days changed with the seasons, that it was not until l884 that a 60 minute hour was universally adopted at the International conference.
It was here that the Prime Meridian of longitude would pass through
Greenwich, England, thus establishes the system of world time divisions that exists today.
However, the first5 timekeeping device was probably the shadow clock, known to the Chinese as early as 2500BC.
Egyptians later utilized shadow clocks (or sundials) from around 1000BC; the Weather clock was used in
Egypt as early as 1400BC to record time during cloudy periods and during the night.
The Hourglass was also a very well known time keeping device together with the burning of graduated candles.
In approx. the first half of the l4cht Century, we see the presence of weight driven mechanical clocks. These early clocks used a bar, oscillating to and fro about a central pivot. This permitted the teeth on a “verge” wheel to escape one by one thus releasing power intermittently to the clock mechanism which enabled its hands to show the time. This system continued to be utilized until around the middle of the l8th century. As all early clocks were weight driven and made mostly to strike the hour, most were found in prominent buildings for public utilization.
Coiled springs was a real breakthrough in about l500, and paved the way for small portable timepieces of all kinds. We saw the emergence of these in Italy around 1500, however, the German, Peter Henlein is credited with the idea of producing a watch that was specifically intended to be worn on the chest or carried in a purse.
Over time, these time pieces became smaller and smaller, but little improvement in the performance. Huygens, in l657 created the first pendulum clock, and shortly after, in about 1660, English physicist Robert Hooke perfected and used flat coiled balance (or hair) springs in watches. This is when the art and skill of watch and clock making parted and became separate trades all together. This enabled errors to be reduced to minutes rather than the hours per day. Thomas Tompion, George Graham and Thomas Mudge all improved on each others ideas and led to the picket watch era of the l800s and the wrist watch era of the 20th century and beyond.
The first quartz crystal clock was developed by Warren Morrison at the Bell Telephone system of
America laboratories in l927.
Its precision and stability led to its adoption as the primary time and standard in the l930s and 40s displacing pendulum clocks.
Eventually, quartz clocks achieved and accuracy of less than 1/100
th of a second per day.
The invention of the transistor in l947 which would later see electronic circuits miniaturized to the point where an electron watch would be possible.
The first battery powered wrist watch was produced by the Lip Watch Company of
France in l952.
Hamilton Watch Company of
USA claimed the world’s first commercially produced electric watch in l957.
In November l959, the Bulova Watch Company announced the arrival of the world’s first electronic watch – the Acutron. A revolutionary concept in that it used a tuning fork vibrating at 440 hertz in place of the traditional balance as well as transistor switching to supply maintaining power. During the l960’s we saw Ebauches SA, Citizen, Junghams and Seiko also introduce electronic watches, using transistor switching in place of earlier mechanical contacts and were much more reliable.
The first Watch to use and electronic digital display was made by HMW Industries of USA under the Pulsar brand.
This used tiny light emitting diodes to form the display, a system later discarded because of its heavy current demand on batteries.
The first liquid crystal display was produced in
Switzerland in l972 – providing a constant indication, instead of a button that had to be pressed to see the time.
Many, many improvements have been made and great sophistication has become apparent in terms so functions and longer battery life etc. and of course recently, the commercialization of the Ground Positioning Systems (GPS) radio control and mobile telephone function, and appears to me, no end in site!!!!
Quarts versus Mechanical?
The difference is their accuracy which is determined and controlled by an oscillator or balance and the power source, either in spring or a battery.
Mechanical watches use a balance wheel fitted with a flat spiel spring as the oscillating element. It is would manually by turning a winding crown or auto-magically by a rotor weight that swings backwards and forwards with the movement of the wrist.
Treaded with care and regularly maintained, these watches will last for a very, very long time and can be stored for long periods with out the worry of internal damage through leaking batteries, this feature is particularly beneficial for dress watches or those not worn regularly.
Downfall of Mechanical watches is that they have a relatively small power reserve – after winding, rarely more than 40 hours without winding again. The automatic winding systems only work on movement, thus, not on the wrist, no movement, not winding!
Quartz is named for the quartz crystal used to make the oscillator. An electric charge will cause quartz to bend, and bending the quartz causes it to generate an electric charge. When a battery is the source of the electric charge, it supplies the power to the circuit which then produces an alternating current. The physical dimensions of the crystal will determine the frequency at which it then will oscillate. As it oscillates, it generates a current very stable, alternating, which is transmitted back to the integrated circuit.
Quartz Watches offer much greater accuracy for timekeeping. Improvements in design and technology produce watches now which can run for many years on a battery. Because the quartz watch have few mechanical components, designers are able to produce very slim and elegant watches. The slimmest available is less than 1mm total thickness, from case back to glass. Analogue displays (with hands) are easier o read than digital displays. At a glance the wearer can determine not only the time but the time remaining until the next hour and the time elapsed since the last reading.
Quality is the real difference!
The quality of the watch case will be a good indication of the overall quality of the watch. The material which the case is made from is a good indication as a precious metal case (i.e. gold and platinum) are not fitted with lower-grade movements.
Gold is an excellent case material because of its resistance to corrosion and its any-magnetic properties. A quality well-made gold or platinum case will give many years of service if not abused.
Stainless steel is excellent material because of its resistance to wear and corrosion. However, necessary to check that case made entirely of stainless steel and now lower grade plated cases with just a stainless steel back.
Highly scratch resistance metals can be tungsten carbide alloys, ceramic and titanium which can be made in steel or gold-colored finishes – these are more often found in the higher end price range due to costs associated with the materials.
Most popular cases are plated types, and now even plastics, generally watches in the lower price ranges.
Mechanical Movements are influenced by the material the components are made from – highly refined alloys, the higher priced watches.
The higher the quality of the watch movement, the more stable and reliable its performance.
Battery power, the correct battery must be fitted and is best to follow the manufacturer’s recommendation and to have it fitted professionally.
Batteries designed for hearing aids, calculators or cameras may work in watches but their sealing is not designed to be reliable over long periods and they should never be used in watches.
Water-Resistance?
Is the internationally agreed term for describing the qualities of a watch that offers protection to the consumer against damage caused to watches by the entry of moisture.
Water-resistant – is just that, it may resist (not necessarily will) water by immersion in no more than one meter of water for approx. 30 minutes. However, not guaranteed by the manufacturer or the retailer.
It will not resist water for any depths more than this, and most certainly not for any length of immersion.
If a Water resistance case is opened it may not be resistant again. It is recommended that any watches that are marked water resistant, they be returned to the manufacturer for battery replacement.
Divers Watches?
The watch must be subjected to water immersion without damage to 200mtrs, Dial clarity, Ability to resist the corrosive effects of salt water; cases are much stronger and better sealing.
There is Standard for Divers Watches, which was ratified in
Australia in l996.
Caring for your Watches
Mechanical:
- Should be wound daily, unless automatic (at beginning of the day).
- May vary in timekeeping, 15-30 seconds a day is not unusual
- Serviced and re lubricated about every three to four years.
- Performance can be affected by exposure to strong magnetic fields
- Auto winding systems need to be worn six to eight hours a day to ensure they stay fully wound
Quartz:
- Should be told at point of sale the battery life, that they should be removed as soon as watch stops to prevent damage from substance that may leak out
- What timekeeping accuracy that may be expected
- Those with auto generating systems need to be work for six to eight hours a day to function properly.
All Watches:
- Should be told at point of sale if they are water resistance
- The affect of wear, exposure to chemical, rough treatment and ageing of the gasket with watch cases.
- Exposure to extended periods of vibration
- Dress Watches usually offer a lower level of protection against water resistance, dust entry and rough treatment.
Servicing?
All good quality watches should be serviced regularly. Reputable jewellers and watchmakers should have established their businesses to provide high quality specialist services and it should be an aspect that sets them apart from retailers who rely heavily on price alone to sell their products.
Many customers own high quality watches which are increasing in value due to the fact that they are no longer made or have become collectables due to the reputation of their makers or technology inherent in their construction. It is most important that those handling these items recognize their value, handle them appropriately and offer the high quality service they deserve.
