Patek Philippe Watch

Patek Philippe is one of the most prestigious watch companies in the world, having a long history of artistic and technical excellence. It all began in 1839 when Antoine Norbet de Patek and Francios Czapek, both Polish migrants living in Geneva, started Patek, Czapek & Co. This watch making partnership lastest until 1844 before being amicably dissolved (the partners often did not agree). During this time Patek & Czapek did release one of the first crown wound pocket watches (1839) [before this time watches were wound with a key]. 1845 saw Patek and new partner Jean Adrien Philippe, whom Patek had met at the Paris watch show the previous year, start up Patek & Co. The company changed its name in 1851 to Patek Philippe & Co.

Patek Philippe made the first ever wrist watch in 1868, this being one of several important contributions that Patek Philippe has made to watch making history. In 1925 they produced the first wrist watch with a perpetual calander, but production problems meant that it was no until 1941 that series production was possible with the model number 1518 (with chronograph). Patek Philippe also produced its first wristwatch with a minute repeater in 1925, and a range of 40 of these models continued to be made up until 1962.

Patek Philippe released its first quartz watch in 1970, amd like every quartz watch it has produced since, the time was not displayed as digital or liquid crystal, but always as watch hands. Patek Philippe is not a mass producer of watches, only producing about 50 per day, and of the watches that it does produce some 20 - 30% more are still mechanicals over quartz movements. Patek philippe has always focused on the luxury end of the watch market. It is this focus that saw Patek Philippe in trouble in 1929, when many watch makers dissappeared, by which most of the company was sold to Fabrique de Cadrans Stern Feres. The Stern family is still heaviliy involved with Patek Philippe today, but the descendants of the Patek and Philippe family no longer have any involvement. It is also this history of focusing on the high end luxury watch market that makes Patek Philippe watches so collectable now days.

If you want to buy a top quality watch,Patek Philippe is a good choice for you,also you can choose Rolex,Omega,U-Boat,Bell&Ross,Richard Mille,Porsche Design,Tag Heuer,Breitling and Rado.

How to Get Used to Wearing a Watch

Often times when people start wearing a watch, they are not used to it, and feel awkward and unconfident. Watches can be useful for telling the time, and in some cases, the date too.

Steps

1. Pick something that you like. You don't want anything too sharp, tight, or loose. You should like the way it looks and it should feel comfortable. It should be waterproof and somewhat durable too. For the band, metal is the fanciest but it's also usually heavy and fragile; for more casual use, you can have a nylon Velcro fast-strap or a leather band, but never plastic, as it can easily snap and does not absorb sweat, causing the inside to be really sweaty.

2. Ignore it. Don't constantly fiddle with or take it off. Just act like it's not there and you will forget it's there.

3. With a shirt makes it easier. If you have a shirt or something down over your wrist, you may be less likely to notice the watch as much.

4. Wear it as much as possible. A widely accepted rule of thumb is that the more you wear something, the faster you will get used to it.

5. Most importantly, enjoy wearing it

Tips

· Periodically fine-tune it to be at the exact time. You can use time.gov as a basis.

· Take good care of it.

· Clean it often.

· If you wear it more than 50% of the time, you will start to always feel like you need to know the time and deprived when you don't, and also, your wrist will feel naked without it.

Warnings

· Make sure you don't lose your watch.

· Don't let the face get scratched by going to sleep with it, playing rough sports or activities.

· Wear it at home but remember to remove it before you shower unless you have a water-resistant watch.

How to Tell if Gold Is Real

In the United States, it is illegal to sell a product as gold if it is less than 10 karats. Here are a few tests you can run to test if the gold is real without damaging it.
Steps
1. Before purchasing the gold, check the label, if it has one. On rings the stamp will be on the inside and on bracelets and necklaces it will be in the clasp.
2. If the label does not say 10k, 14k, 18k, or 22k, then it is probably not real gold.
3. Ask the person who is selling it about how many karats are in the piece of jewelry.
4. Test the density of gold. It is about 19.3 grams/cm cubed, which is much higher than most other metals. Platinum, iridium, osmium, and neptunium are the only metals with density higher than 20 grams/cm cubed. To test its density, use a scale and a graduated cylinder. First weigh the gold, and then put some water in the graduated cylinder. It doesn't matter how much, but keep note of the amount. Then put the gold inside the water (this won't damage it) and note the water level. Get the difference between the two numbers for the volume of the gold. Density= mass/volume. If the answer is close to 19 grams/cm cubed, then it is real gold.
5. If you do not care if there is a small dent in the gold, bite into it. Because real gold is softer than fake, if it stays intact then it is fake.
6. Use the streak method. Take the gold and streak it across an unglazed piece of porcelain. If it is black, it is fool's gold, but if it is goldish-yellow, it is real.
7. Another test is the hardness test. According to Moh's scale, you should not be able to scratch glass with gold, but with fake gold, such as Pyrite, you should be able to.
8. Pyrite, which is fake gold, if magnified 10 times, is actually made out of tiny cubes.
9. When gold is hammered, it will not break, but might bend. However, if Pyrite is smashed, it will break into tiny little cubes.
10. You can take it into a shop where they can test if it is real gold. This is an inexpensive way and it takes only a short amount of time.
Tips
Some methods will change the look of the gold, only if it is fake. You can put nitric acid or vinegar to test it. It will not change if it is real. Be very careful with nitric acid, it can burn your skin.
Warnings
· The density test will not work if the gold has gems or other material.

Over Wind or Over Wound Watch Mainspring

Where in the world did the phrase, "I over wound my watch" come from anyway? Do you think you can actually over wind your watch? Did someone tell you that you over wound your watch?

These are all good questions and to an extent, the term "over wind and over wound" are correct. Yes we know and have heard it at least a thousand times, that "you can't over wind" a watch. The people who say that have heard the term before, and don't know what they are talking about. They seem to parrot the phrase in order to impress someone with their knowledge of watches. Well, here we go, they may be right and they may be wrong as the term was used.

The term "over wind" originated back in the days of blue steel mainsprings and animal fat oils that were used to lubricate watches. So lets get one thing out of the way now. In technical terms, you can't actually over wind a watch. The mainspring will only go so far into its coil, if you could keep winding your watch, something would break. The stem might be the first thing to break, then for sure you would strip the teeth off the clutch. If the clutch and stem were to withstand the stress, then for sure the teeth in the crown wheel and ratchet wheel would strip. Now this would be over winding your watch. Now the details...

Blue steel mainsprings were rather weak in terms of their ability not to take on a "set." This is when the mainspring conforms itself to a little larger in size than the space it occupies within the mainspring barrel. When they take on a set, it is difficult for the fully wound mainspring to release itself from its own coils and powering the watch.

Watches were lubricated with animal fat oils. Over a period of about one year, these types of oils would tend to gel and become thick and tacky. Now, if you have both of these elements present in your watch, and you wind it up all the way, as far as it will go, the thick oil will bind the coils of the weak mainspring together and the coils will not slip and power the gear train. Here, you have now over wound your watch. Had you only wound it up say three forths of the way, the mainspring would still slip and provide some power to your watch. So you see, in this sense, you can and did over wind your watch.

Old jewelers many years ago, would tell people that they over wound their watchs and that was the reason they stopped. For the average customer, the lack of information was OK. Why go into great detail as to why the watch stopped. It just took time away from the bench. The jeweler would tell them the watch needed to be cleaned. This took care of the problem for about a year or so until it needed to be cleaned again.

It is interesting that now, after all of these years, we still hear people saying that they, "over wound" their watches. There are still many old watches out there that have not been serviced for decades. People will wind them up, and they will run for awhile, then one day, the dreadful "over winding" takes place.

White alloy mainsprings and synthetic watch oils. These were very important inventions in the field of horology. The white alloy springs for the most part would not break and maintained their original "S" shaped form. The new oils did not gel and become thick like the old animal fat oils. Watches could go for much longer periods of time without the need for yearly cleaning. With these modern advances, the old terminology of "over winding" started to slowly fade away, just like the old watchmakers who coined the phrase in the good old days. A period of horological history that has long since vanished.

We hope that you found this topic interesting and useful. If we can help you with your questions or solve your "over winding" questions.

Wear Your Watch on the Right Wrist to Protect Your Heart: Common Sense and the Left-Handed Heart Meridian

Right-handed people usually wear a watch on their left wrist. But wearing a battery-powered watch on the right is safer for the heart meridian running down your left arm..
If you’re right-handed, you probably wear a watch on your left wrist. You might consider switching, however, when you consider the impact that your watch’s battery can have on the health of your heart meridian and, ultimately, on your heart.

What is the Heart Meridian?
The heart is one of the 14 major organs and systems in Traditional Chinese Medicine. Each of these organs has a corresponding meridian, a line of energy flow through the body that becomes strong or weak in tandem with that body part. In healing a weakened organ, the energy of the related meridian is used both to diagnose the health of the body and as a means to begin to strengthen it.
The meridian system has been used and translated into dozens of different energy healing techniques (including energy psychology, Energy Medicine, Touch for Health, Brain Gym, and accupuncture) because the approach is so effective.

How Does a Watch Battery Affect the Meridian?
The meridians are subtle energy structures and can be very sensitive to the objects and materials that surround our bodies. Magnets and other metals, in particular, are known to affect the energy of the meridians.
Wearing any piece of jewelry for long can bring on fatigue or have the opposite effect and make the wearer over-energized. Some people are so sensitive that they have to remove earrings or other jewelry after only a few minutes, because the metal charges with their energy and begins to affect the way they feel. Glasses with metal frames can have tiny holes drilled at the end of the “arms” to discharge energy, but that can’t be done to most decorative jewelry or to watches.
Anything that crosses over a meridian is likely to affect it. 6 of the 14 meridians have paths that run down the arms and fingers, so bracelets, rings, and watches all have the potential to affect these lines of energy. Watches are especially a hazard because of their batteries and the mechanical motion, both of which have the potential to disrupt the normal flow of meridian energy.

Why is the Heart Meridian, in Particular, at Risk?
Because the heart has its own rhythm and our very life depends on it not being disrupted, most healing approaches that use meridians are very cautious of anything that may affect the heart meridian.
A watch’s mechanical motion is mildly disruptive, but watch batteries, with their intense electromagnetic charges, can be very hazardous to the steady flow of energy in a meridian - especially for people whose hearts are weak or who know they are at risk for a heart attack or other circulatory problems.
The heart meridian occurs on both sides of the body, so it runs down both arms and hands. The heart meridian on the left side, however, is the more significant because of the position of the heart in the left side of the chest cavity.

Solutions to the watch-battery energy dilemma
You may have heard of people whose bodies make watches stop. They can put on a watch and within seconds, minutes or days, the watch stops running. People like this have one of the solutions spelled out for them: Don’t wear a watch. It’s easy to rely on wall clocks or a cell phone timer instead.
Alternately, there are some watches available that need to be wound or that wind themselves based on movement. These watches are a safe alternative for most people that won’t disrupt the heart.
If you absolutely must wear a battery-operated watch, wear it on your right wrist.
