Depending on how old you are,you may or may not remember observing your dad wind his watch each night before going to bed. If he did not perform that ritual,he would certainly wake to a watch that had stopped. With the advent of the automatic watches,those rituals were banished. What makes it automatic? There really is not that much change from the basic mechanism to keep the watch working, but how that mechanism is powered really altered the way we maintained our watches. Mechanical watches on the whole work in a comparable method. They all simply require a movement of a series of gears to “tick” of increments of time, which in turn registers as movements of the hands on the face of the watch.
Inside the watch is a rotor which sits on a staff in the middle of the watch’s movement. What it does is rotate in a circular motion and winds the mainspring which is the source of power in mechanical watches. With regards to an automatic watch,the winding of this spiral spring is done automatically with any arm or wrist movement. Self-winding, automatic watches work fantastic for individuals who wear the watch everyday, alternatively, if you do not wear the watch often, you will need to note it needs manual winding about twice a week. On the whole,automatic watches will stay working better if they are wound manually about once every two weeks for the simple reason this helps keep the watch lubricated.
One of the big misconceptions about them are they never need any winding, since it all depends on the movement of the arm to keep it functioning well. A power reserve allows the movement of your watch keep time for anywhere between 10 and 72 hours. There is something called a power reserve, and the bigger the reserve, the longer your automatic watch will keep running without further movement or manual winding. Rolex was the first watch manufacturer to devise and patent the rotor system that is still used today. They called it the Perpetual and it was part of the popular Oyster line created in the early 1930s. Emile Borer was the Rolex technician who came up with the system, but he was not the first to develop a rotor.
In 1770 that distinction went to Swiss watchmaker, Abraham-Louis Perrelet. This was quite the invention because it wouldn’t be until much later in time that wrist watches were worn, and there just wasn’t enough physical movement with a pocket watch to make it a feasible way to move the rotor and wind the mainspring. Automatic watches vary from quartz watches which are powered by batteries and not by either a manual or automatic winding system. Powered by a battery, the quartz crystal inside a quartz watch vibrates nearly 33,000 Hz. The frequency at which the crystal oscillates depends on its shape, size, and the crystal plane on which the quartz is cut. The positions at which electrodes are placed can slightly change the tuning, as well.
If the crystal is accurately shaped and positioned, it will oscillate at a desired frequency. In nearly all quartz watches, the frequency is 32,768 Hz, and the crystal is cut in a small tuning fork shape on a particular crystal plane. This frequency is a power of two (32,768 = 215), just high enough so most people cannot hear it, yet low enough to permit inexpensive counters to derive a 1-second pulse. A 15-bit binary digital counter driven by the frequency will overflow once per second, creating a digital pulse once per second. The pulse-per-second output can be used to drive many kinds of clocks. Watch batteries last about two years, where automatic watches have a never ending source of power:movement or motion. Quartz watches account for most moderately priced watch sales today, but connoisseurs of watches still like the prestige and elegance of a superbly crafted mechanical watch. Automatics have started to regain some of the quartz market in recent years accounting for huge increases.
Lubrication is essential to keeping an automatic watch running well. Watches can be lubricated by manually winding the watch periodically and taking it in to a jeweler once about every 3 to 5 years. When winding an automatic watch, just wind it about 30 to 40 times or until you feel some resistance. It is a good idea to keep the watch in a watch winding box is that is a good way to keep the watch lubricated. Automatic watches are also reasonably priced. They actually come in every price range. Some economical brands include Invicta watch and Orient watch, and then the price can reach into the very expensive range depending on the embellishments or the prestige of a specific brand.
FAQs About Automatic Watches Automatic watches are mechanical timepieces that offer many benefits over traditional wind-by-hand watches and modern battery-operated quartz watches. Women's and men's automatic watches are particularly fashionable in the luxury watch field, and are also obtainable at many price points. Automatics have been available since the 1920s, but they didn't come into common use until the 1950s when watchmakers began producing them more economically. Men's and women's watches with automatic winding technology are stylish, attractive, interesting and low-maintenance.
What is an automatic watch? An automatic watch is a timepiece that operates through the continued movement of the wearer's wrist. Automatic wristwatches don't need winding if worn on a daily basis. The energy is preserved by using a half-disc metal weight, called a rotor, that spins when the arm is moved. This energy is used to power the watch and can keep the watch going at night or while the watch isn't being worn. Stored energy in an automatic wristwatch can keep an unworn watch running for 24 to 48 hours.
Is an automatic watch different from a wind-up watch? Men's and women's automatic watches are mechanical, like traditional wind-up watches. The only difference is that the conventional manual watch needs to be wound daily. Automatic wristwatches use the same parts and technology as mechanical watches, but they are wound automatically with the motion of the wearer's wrist.
Can an automatic watch be wound too tightly? An automatic watch can be wound constantly and never break. You can wear your automatic watch day and night, and the watch will never be over-wound.
What happens if my automatic watch runs out of power? If your automatic watch is unworn for 24 to 48 hours, it will likely stop running. An idle automatic can be wound with 30 rotations to restore its energy. Even just a couple of turns of the crown or a brief shake will usually get it started again. Simply wind the watch and set the time and your watch is ready to go again.
How accurate is an automatic watch? A high-quality automatic mechanical watch is fairly accurate. Mechanical watches, including automatic varieties, can lose or gain as much as two seconds of time a day and as little as one second of time per week. Each mechanical watch is different,and you will quickly get to know how accurate your watch is.
What is so special about an automatic watch? After the quartz watch boom of the 1970s,men's and women's watches with mechanical craftsmanship and quality made a comeback in the 1990s. Watch wearers recognized the benefits and pleasure of interacting with a mechanical device as part of their daily routine. An automatic watch, by virtue of being a machine, signifies quality and the owner's fascination in the mechanics of timekeeping. Traditional mechanical women's and men's watches also offer an aesthetic value that is difficult to replace with battery-operated timepieces. Automatic watches give consumers a mechanical watch option that is easy to use, because the automatic mechanism eliminates the need for manual winding.
Are automatic watches expensive? An automatic watch can be expensive. Many luxury watch brands offer a wide range of automatic watches that are intended to be investment pieces. Automatic watches maintain their value for the reason that they are well-made and appealing. A number of entry and mid-level brands offer well-engineered automatics in a wide range of prices. In the last 20 years, there has in addition been a tremendous surge in vintage watch collecting trends. A well-maintained 1950s or 1960s automatic wristwatch, which often possesses a contemporary design, can provide a lifetime of trouble-free service at a moderate cost and add style to your daily life.
