What Do I Need To Know About Watch Battery Replacement?

It is highly recommended that you contact a watch repair professional who can perform a watch battery replacement without damaging your watch. Simply opening a watch case can cause damage if handled improperly. For example, some watches have cases that twist, while others snap to open. Opening the cases of luxury watches also requires specially-designed tools. Water-resistant watches, especially, should only be opened and re-sealed by trained watch makers with the correct tools and testing equipment.

When considering watch battery replacement, you must use the exact type battery in the same position as the prior battery. Polarity markings must also be observed. If a wristwatch has two batteries and only one battery is dead, both batteries should be replaced. White powder or liquid in the battery compartment can be a sign of previous battery leakage which may have damaged the movement.

As of January 1, 2012, some states in the U.S. will require the use of only 0% mercury button-cell batteries. Old batteries should be properly recycled to avoid mercury contamination to the environment.

Can A Watch Crystal Still Chip If It’s Labeled “Scratch Resistant?”

Yes, it can still chip. However, watch crystals which protect the watch face can be made to resist scratches from everyday wear. Watch crystals made with synthetic sapphire—or a combination of synthetic sapphire and mineral glass—provide the most scratch resistance.

What Is Eco-Drive?

These watches use a solar conversion panel and an energy cell to provide power to the watch mechanism. The eco-drive watch can use light from any source to generate electrical power. This power is held in a storage cell that does not have the charge/discharge cycle which is typical of most types of batteries, which means eco-drive watches can give long term performance.

What Does Jewel Mean?

The term “jewel” refers to a type of bearing in a watch mechanism. Modern jewels are typically made of synthetic sapphire or ruby. Jewel bearings reduce friction, therefore they offer a high degree of accuracy in timekeeping. The number of “jewels” is often used to characterize the quality of a watch. A watch with 17 jewels or more would indicate a high quality, precision watch. Jewels in watches have little monetary value.

What Does “Water-Resistant” And “Water-Proof” Mean?

The term “waterproof” has not been used to describe watches since the late 1960s. “Water resistant” is now the term used to describe a watch’s resistance to an ingress of moisture. A watch receives a water resistance rating based on laboratory pressure tests. These tests simulate the water and pressure a swimmer or diver is subjected to under static conditions. However, it’s important to note that most water activities will subject a watch to motion and various temperatures and water pressures, all of which are dynamic in nature. That’s why many manufacturers and watch makers suggest you purchase a water resistance rating that is two levels beyond the static rating you would select for your anticipated use. You may see these “levels” of water resistance sometimes expressed as “Atmospheres.” For example, a watch rated for:

3 Atmospheres (100 Feet or 30 Meters) can withstand splashes or brief immersion in water, but may not withstand the rigors of swimming.

The Technology

Each accessory in the Philip Stein collection contains our unique proprietary technology disc. Designed to be worn any and every day, it helps you to live in tune by re-establishing your personal connection to the earth.

How It Works

We live surrounded by frequencies, and these frequencies affect our bodies.

In the modern world, some of the frequencies in our environment are natural, while others are manmade.

The Natural Frequency Technology in Philip Stein accessories is specially programmed to pick up and channel only those frequencies that are natural and beneficial to our bodies and minds. In other words, our products tune you back to a state where you can perform and live at your best.

The Technology In Detail

Everything – from our own cells and bodies, to the water, plant life, and materials that make up our environments – resonates or operates at a certain frequency.

As living beings, we have always been surrounded by natural frequencies, and it’s likely that we’ve become accustomed to living in balance with them. The modern age, however, has created artificial frequencies that can interfere with that balance.

Philip Stein Natural Frequency technology works in the same way as a finely-tuned antenna, harnessing and channeling beneficial natural frequencies directly to your body. The result is a greater sense of wellbeing and balance, day or night, no matter where you are. Our technology helps you live in tune.
