Arctos is the first German watch company, the automatic watch from high-tech ceramics (zirconia ZrO2) and titanium manufacturing. Hight-tech ceramic is a material which is increasingly a more important role in space wins. High-tech ceramic has a much higher strength than metal, after Mohs scale, diamonds are just a little harder. Ceramic tools can e.g. even steel cut. It is an ideal material for watches, under extreme conditions are used. Here is the model number GPW home.

The glasses for watches can be in 3 groups. Plastic lenses, mineral glass and sapphire glass. Each of these types has different characteristics, different application areas and also various fashionable aspects. There is also within these groups different quality standards in the following should be clarified.
also Hesalithglas, acrylic or Plexiglas called – consists of the plastic polymethylmethacrylate (PMMA). They are relatively lightweight and impact resistant. Disadvantage of plastic glasses is their low hardness, so they are easily scratched.
The chemical name for mineral glass is silica SiO2. Good Mineralgäser are not simple window glass. The surface is good mineral glass in the manufacture in a complex procedure chemically hardened. Mineral glasses are much harder than plastic glasses, they are not osmotically and not yellow. But there is also mineral glass damage. Is particularly detrimental when a fraction small glass splinters in the movement reach and cause damage there.
The hardest among Uhrgläsern is undoubtedly the Saphirglas. Sapphire crystals are synthetically by the Verneuil process produced. A small drawback of the sapphire crystal is to increase light refraction of this mineral. It may be more disturbing reflections on the watch shows. Therefore, high-quality sapphire crystals in watches also reflective.
In recent years, in Germany automatic watches receive strong indentation. Because of the differences to quartz watches take watches collector of automatic watches to other requirements and needs.
A clock will move you need when an automatic, the iM is not worn – as your second or third watch – to move. At the latest after 48 hours would your wristwatch without Watchwinder stand still, and thus lose their accuracy. It is the mover to watch a special pillow or anxious in a holder mounted, which with the help of an electric motor slowly around the axis of the clock turns. Thus, the main spring of the automatic continuous tense.
In high-quality moving clocks can be found in the various rule Lift Programs (= rotation programs). Here lies the big difference to approve tenders: these programs are missing the elevator and even the possibility to define the direction of rotation. These programs can be the number of revolutions per day setting. We speak here of “Turns Per Day (TPD). If the interval between the individual turns too large, the clock before the next movement, and briefly loses its accuracy.
Also, there are different mechanisms or pathways, automatic watches watches on the move to fix. Many watches mover offer flexible cushion to the automatic stretches, and then in the corresponding device attached. Especially with very large clocks you should make sure if there are two pillows on the plate mover of the watches are attached, that it is not too close together. Otherwise, might affect the clock and due to the scratching motion.
On very good quality watches and you can move to your specific caliber concerted Lift Program.
When the number of revolutions / intervals per day for a particular watch model you should check the details of the watchmaker or follow the manufacturer. These can be found in the technical data sheet of the built-caliber as TPD. Nor is there the direction of rotation of the caliber specified.
Most automatic caliber need 650 to 900 TPD in the clocks move. However, there is also a new automatic work from glass, with only 450 TPD agents.
Old Auto Works would work with most watches mover overdrawn, so you’re here in a meaningful Einstellprogramme the manufacturer should look out for. In the newer calibers find exactly for this reason a towing spring, which, if the spring tension is too strong, harmless nachrutscht.
Statements that wristwatches with new resins various calibers, if you do not run, are nonsense, as today’s synthetic oils clocks and thus can not be resins. In older calibres, however this risk and thus the use of a watch movement from a technical point of view is recommended.
You should, however, in preference to all technology not forget that most watches movement also a delight for the eye are.
The absolutely perfect time
The clock radio with Eco-Drive need to actually drive a very special name. They are unique watches, with the (image) the two most advanced technologies, which today are: the principle of Eco-Drive and the radio-controlled time. The automatic synchronization of the time with the radio signal from Mainflingen, near Frankfurt, will save the manual time setting. The environmentally friendly Eco-Drive drive, both natural and artificial light into energy converts, makes the battery superfluous. In addition, the watches with a Full (FMC) that the best possible protection of the movement is not receiving power to influence. Functioning of Funkuhren: Funkuhren for Europe with a receiver for the DCF77 signal, which in Mainflingen / Frankfurt is broadcast. Three independently operating atomic clocks generate both a time signal. After comparing these time signals will be interconnected by the master clock signal on the long wave of Mainflingen from within a radius of up to 2000 KM broadcast. This time information is used by the Physikalisch-Technische Bundesanstalt in Braunschweig and produced by Telekom on broadcast transmission towers.
Since the introduction of the world’s first wristwatch with multipolarem radio receiver in 1993, is Citizen Funkuhren at the forefront of technological development. Today’s models continue to impress with your design and technologies used. With the Super Skyhawk has Citizen in 2007 brought out a radio clock, which is capable of the signals from the U.S. time zones, Japan and Europe to receive.
Eco-Drive means “organic drive”. The term “Eco-Drive” comes from the watch manufacturer Citizen for a wide range of solar-powered quartz watches (such as the Promaster series). In an Eco-Drive clock is a special lithium-ion battery, the ever on a solar cell, which also acts as a dial charged. The solar cell is a light cell from silicon, which even natural and artificial light can be converted into electricity. Eco-Drive watches can vollgeladenem with battery 150 to 240 days without light running. This period is called dark power reserve.
Some of Citizen watches have a dark power reserve of up to 8 years. This period is enormous in these Watches achieved by the function of the pointer at a dark time (ie, the clock is no light source) by 24 hours off. The timing is in these internal clocks, however, continued. Once the clock again a light source is suspended, move the pointer to the current time and the clock running.
The secondary battery in the Eco-Drive watches, according to Citizen after 20 years to a capacity of 80 percent.
Modern quartz works offer a precision required for the normal user watches no wishes unfulfilled. The month of change, there is always reason to check the date and, if necessary, to correct them. The Citizen Perpetual Calendar (Ewig calendar) is up to the year 2100 programmed and knows every month bills, whether the date of 30 or of 28 to 1 changes of the month and he also knows when in the case of a leap year at 28 February 29 follows. The programming is therefore up to the year 2100, since under the rules of the Gregorian calendar, a leap year, and thus fails the computing algorithm is not effective.
The rules of the Gregorian calendar:
- All years, which by 4 divisible without rest are leap years.
- All years, which by 100 without remainder divisible, are not leap years.
- All years, which by 400 without remainder are divisible, in turn, are leap years.
The lighting of the future
Each clock contains small self luminous lighting elements, produced by the world’s leading physical Swiss Institute for lighting components Mb-Microtec. These lighting elements (Borosit glass capsules) are firmly embedded in the hands, the hour indexes on the dial and watch divers in addition to the rotation ring. To detect the time at any time, even at dark night to guarantee on all models is the highlight of the position 12 with orange and green color at the other positions elaborated.
The secret lies in the use of tritium. The tritium watches need no external light source to the color on the face of charge, as required conventional fluorescent color, nor they need a push of a button in order to illuminate the dial, such as watches with Elektroluminiszenz needed.
Tritium Gaslichtquellen (TGLQ) are working on the same principle as fluorescent compounds that act directly on the dial-be. a zinc-based fluorescent tritium is suggested.
The essential difference is that this process in a glass tube held inside the lamp with the coating and is filled with tritium.
TGLQ glow around a hundred times brighter than normal fluorescent compounds, and they also have the advantage that the glass tube can be safely handled, because no radioactivity penetrates to the outside. The under high pressure hermetically sealed, tiny fluorescent cells are resistant to water, oil and most corrosive materials. Even extreme temperatures (-170 degrees Celsius to +400 degrees Celsius) and temperature shocks for the TGLQ lighting system is no problem.
The tubes can be found on dials and hands are, since they only have a diameter of 0.5 millimeters have.
For the life of TGLQ: after six years, the glass tubes about 50 percent of its brightness, after 12 years, yet 25 percent to offer – the human eye perceives this as a way, still half as bright as the full performance.
These advantages have TGLQ watches with an absolute must in the world of emergency, safety and security, but also for adventure – and sports enthusiasts made. The U.S. Army has the superiority of the new lights early. Their use in the specification MIL-W-46374F prescribed. Meanwhile, over 300,000 H3 watches in the U.S. armed forces in action.
