1. Water-Resistant Versus Waterproof
A watch marked as water resistant without a depth indication is designed to withstand accidental splashes of water only.

Do not submerge such a watch. Higher levels of water resistance are indicated by increasingly higher acceptable depths, usually indicated in meters.

There are a variety of ways to make a watch water resistant. All such watches use rubber gaskets or "O" rings to seal the case back. A watch with a back that screws onto the case provides a higher degree of water resistance. Some crowns (the "winding stem") actually screw into the case to further increase water resistance.


Usage Recommendations

The following usage recommendations are suggested by the Seiko Corporation of America:

• Water-resistant to 30 meters (100 feet). Will withstand splashes of water or rain but should not be worn while swimming or diving.
• Water-tested to 50 meters (165 feet). Suitable for showering or swimming in shallow water.
• Water-tested to 100 meters (330 feet). Suitable for swimming and snorkeling.
• Water-tested to 150 meters (500 feet). Suitable for snorkeling.
• Water-tested to 200 meters (660 feet). Suitable for skin diving.
• Diver's 150 meters (500 feet). Meets ISO standards and is suitable for scuba diving.
• Diver's 200 meters (660 feet). Meets ISO standards and is suitable for scuba diving.

Please note that we do not recommend swimming or diving with your watch unless it has a screw-down crown (also known as 'screw-lock' or 'screw-in' crown) and is water-resistant to at least 100 meters.

2. Keeping Your Watch Dry
Always make sure your watch is dry after it has been exposed to water. By taking a few minutes and thoroughly drying your watch with a lint-free cloth, you will prevent rust from forming. This is a key point in ensuring the long life of your watch.

3. Caring for the Crystal

The crystal is the transparent part of the watch through which you tell time. As we discussed with water, a watch may have a scratch-resistant crystal, however no crystal is truly scratchproof. Therefore, it is not advisable that you toss your watch onto the dresser or into a drawer at the end of the day. It's better for the watch to store or wrap it in a soft cloth before placing it down. The more care you take with the watch, the less scratches you will end up with. Replace broken or scratched crystals immediately. Even a hairline crack can let dust or moisture into the mechanism, threatening its accuracy. If you place the watch in a drawer with other jewelry, this too may scratch the watch, as it might rub against the other pieces. Another suggestion would be to store the watch in its original case, since these cases are generally soft and made specifically for the watch.

4. Metal Versus Leather Bands

If you participate in activities that cause excessive sweat or perspiration, you may want to consider getting a watch with a metal bracelet or rubber strap, instead of a leather strap. Watches that have natural and genuine leather straps will gradually deteriorate with constant exposure to perspiration. Metal bracelets would best be classified as "dress" watches.

5. Battery Replacement

Watches that run on batteries are known as 'Quartz' watches. The batteries will last anywhere from one to several years. How will you know when the watch needs the battery changed? Most of the watches sold by WorldofWatches.com come with free lifetime battery replacement. Send the watch in with your receipt, and WorldofWatches.com will replace the battery. If a watch was not purchased from WorldofWatches.com or did not come with free lifetime battery replacement, consider taking it to a local watch professional for battery replacement.

Watches that do not need battery replacement include automatic (self-winding) watches and solar-powered watches (which have a rechargeable battery). You may want to consult the watch's manual if you're not sure what type of watch you have.

6. Cleaning Your Watch

The best way to clean your watch is by using a lint-free cloth and a toothpick. Use the toothpick to clean out any dirt buildup in the bracelet or casing of the watch and the cloth to wipe it clean. If it is water-resistant, give it an occasional cleaning with a mixture of warm water and a mild soap. If the strap is leather or non-metal, clean only the case.

7. Servicing Your Watch

Like any other piece of machinery, a watch must be cleaned, oiled, and serviced. Every couple of years, you may notice the watch losing time or running fast-or it may stop working altogether. Just take your watch to a local watch professional for servicing.

8. Automatic Watch Maintenance

Although automatic mechanical watches do not have batteries, some easy-to-follow maintenance is necessary for continued and long-lasting good use.

Self-winding automatic watches depend on the movement of the arm to operate and do require some winding, even if you wear your watch on a daily basis.

If you wear your Automatic watch everyday, it is best to wind it once, every two weeks to keep the wheels in motion and oil fluid. Simply wind the crown (the same knob used to adjust the time and date) until you meet slight resistance.


If you do not wear your Automatic watch everyday, you should try to wind it at least twice a week to ensure continuous operation, as well as keeping the inside mechanism in complete running order.

Try to wind your mechanical watch at the same time every day. This is extremely beneficial for the mechanism. You may want to make it a routine, winding it every morning when you wake up.

Avoid setting the day and/or date (if your watch has these functions) at night. The day-date mechanism is activated during the nighttime hours and could be disrupted if set at this time.

Also, always avoid wearing your mechanical watch if you are playing a sport requiring continuous arm motion (e.g. tennis, baseball, golf), since continuous arm motion could damage the movement.

9. Watch manufacturers advise people to have their mechanical watches serviced regularly even if they're working fine. Why is that?
Like a car, a mechanical watch needs to be lubricated regularly to keep it running smoothly. Over time, the oil will deteriorate and friction between the movement's part will increase, causing abrasion and making the watch less accurate. In addition, the friction can create a very fine dust that will itself act as an abrasive on the watch movement parts.

10. How often does a mechanical watch need to be serviced?
Manufacturer's recommendations vary, but most range from every three to five years.

(Top of Page)



11. What happens to it when it goes in to be serviced?
The watch is taken apart and the bracelet and case are cleaned ultrasonically and polished. The pieces of the movement are cleaned chemically and examined. Worn parts are replaced. The movement is then reassembled, lubricated and regulated. Then, if the watch is water resistant, its water resistance is tested.

12. Where should you take your watch to have it repaired or overhauled?
If the watch is under warranty, the warranty may be invalid unless you take it to a service center authorized by the manufacturer. You can get a list of authorized repair centers from the manufacturer. If the warranty has expired, you can take it either to an authorized center or to a reputable repair shop.

13. How much does an overhaul cost?
It varies a great deal, but consumers can generally expect to pay upwards of $100 - sometimes a great deal upwards- for an overhaul of an uncomplicated automatic watch. As a rule, the more expensive the brand, the more expensive the overhaul.

(Top of Page)

14. How long does the watch have to remain in the shop?
This, too, varies by repair shop, but turnaround times for overhauls are generally measured in weeks - two or three in many instances.

15. Do quartz watches need to be serviced like mechanical ones?
No. Quartz watch movements do not need nearly as much maintenance as mechanical ones do. That's because they have far fewer moving parts -just the gears that move the hands. (A digital watch has no moving parts at all). All that most quartz watches really require is that when the case is opened for a batter change, it be cleaned of accumulated dirt. However, some expensive quartz analog watch movements should have their gear train lubricated ever eight to 10 years. For inexpensive quartz watches, this isn't worth doing.

16. How often does a watch's water resistance need to be checked?
All water resistant watches need to have their water resistance checked ever time the batter is changed or the case is opened for any other reason. That's because when the case is opened, the caskets that keep the water out of the case are dislodged. (These gaskets, or O rings, are located inside the case at the joints where the case meets the case back, crown and crystal.) For this reason it's important that when the battery in a water-resistant watch needs to be changed, the watch be taken to a repair center that has water-resistance testing equipment. In some instances, water-resistance should be checked between battery changes. If the watch is worn in the water, frequently or exposed to a lot of sweat, it should be checked at least ever two years and, if exposure to water is very frequent, ever year.

17. Do you need to wind a mechanical watch every day?
The watch will run better if you do. You always get better performance from a watch when it's fully wound than when it's wound down. It's best to wind it even if you don't intend to wear it. That will prevent the movement's lubricants from congealing.

This doesn't, of course, apply to an automatic, or self-winding watch. This type of watch should be wound initially to get it started. If the wearer is reasonably active and wears the watch for 12 to 15 hours a day, it will remain fully wound.

18. Does it matter which direction you turn the crown when you're setting a watch?
On most mechanical watches it doesn't. On some, particularly those equipped with calendars, you should only move the hands clockwise. The manufacturer's instructions will include directions for setting.

On quartz watches, it's OK to move the hands in either direction to set them. Manufacturers point out, though, that you can eliminate the free play in minutes hand by setting it in the following way (a quartz watch, unlike a mechanical one, tends to have play in its minutes hands due to the lack of tension in the gear train): Move the minutes hand clockwise until it is a few minutes past where it is supposed to be, then move it counterclockwise back to the correct spot.

19. Will heat and cold affect a watch's accuracy?
Heat and cold will affect the time-keeping ability of a quartz watch. Quartz crystals, whose extremely steady vibrations are responsible for the unrivaled accuracy of quartz watches, are cut so they perform optimally at room temperature. A temperature of 100 degrees Fahrenheit will throw the timing off by about 1 second a day, as will one of 32 degrees Fahrenheit.

Extreme temperature will also affect the accuracy of a mechanical watch, but not as much as other factors (see below). One reason is that hot and cold cause the metal parts of a watch movement to expand and contract (though advances in metallurgy have made this less of a problem than in the past). Another reason is that heat and cold affect the viscosity of the oil that lubricates the movement, and thereby affect the movement's accuracy.

20. What other factors affect the accuracy of a watch?
In a mechanical watch, wearing habits such as when the watch is wound, how long it's worn each day and what position it lies in when it is not being worn all play a critical role in determining how consistently a watch runs. Although a typical mechanical watch might gain or lose about 5 minutes a month, it's possible, by adjusting the watch to fit a wearer's regular habits, to achieve much higher accuracy than that. The more consistent your wearing habits, the more consistent the time-telling will be.

None of these factors make any difference with a quartz watch. With quartz, temperature is the only variable that affects the accuracy of the movement.

21. Can a mechanical watch be worn playing sports?
In general, yes. All or nearly all mechanical watches manufactured today are equipped with anti-shock devices that protect the watch's balance-staff pivots - the part of the watch movement most vulnerable to damage from impact. These devices are usually effective enough to protect the watch from the shock it encounters when you hit a tennis or golf ball, for instance.

Nonetheless, there is a small change that an especially hard knock could damage not only the balance but the rotor axle, which is some automatic movements serves to secure the rotor to the watch movement. So deciding whether to wear your mechanical watch or not while playing sports is a matter of risk assessment. The odds, however, are on your side.

(Top of Page)

22. Is the same true of a quartz watch?
There is very little chance of damaging the movement of a quartz watch while playing sports -a quartz watch does not contain the delicate balance-staff pivots that make anti-shock devices necessary in mechanical watches. You can, of course, damage other parts of the watch -the crystal of instance- whether the watch is quartz or mechanical.

23. Will anything damage a scratch-resistant sapphire crystal?
Don't be misled by the term "scratch resistant". It doesn't mean "scratch proof". The most scratch-resistant crystals are made of synthetic sapphire, an extremely hard mineral that measures 9 on the Mohs hardness scale (diamond, the hardest natural substance known to man, measures 10). Despite its high rating, sapphire can be abraded by some materials. Brushing against a synthetic stone surface, like those found on some furniture or walls, for example, could cause a scratch.

Also keep in mind that the more scratch-resistant a material, the more brittle it is, so scratch-resistant crystals are more likely to chip or shatter than non-scratch-resistant ones.

24. Will wearing a watch on the inside of your wrist affect its accuracy?
If it's a quartz watch, no. The position of a quartz watch has no bearing on its time-keeping ability.

A mechanical watch is a different story. Mechanical watches are regulated at the factory to run optimally on a right-handed person who will wear the watch on the outside of his or her wrist -i.e. crown down, dial up. The watch will not run as accurately in any other position, unless it is adjusted to do so. If you want to wear the watch on the inside of your wrist and have it run as well as if it were on the outside, you'll have to have it re-regulated.

25. How long will a quartz-watch batter last?
A silver oxide battery will last two to three years. Lithium batteries will last 10 years or more. (They aren't interchangeable. Watches are designed to use either silver oxide or lithium batteries.)

(Top of Page)


26. Can you hurt a watch by pulling the crown out too hard when setting it or, in the case of a mechanical watch, winding it too much?
It's unlikely you would hurt a watch doing either of these things. You would have to pull extremely hard on the stem to damage it while setting the watch. It is in theory possible to overwind a mainspring so that it breaks, but watch repairers say this rarely happens.

(Top of Page)


27. It is true you can preserve a quartz watch's battery power by pulling out the stem if you won't be wearing the watch for a few days?
Pulling out the stem saves 75% to 80% of the watch's energy because the gears and hands aren't turning. However, he points out, the savings is marginal when you consider that a silver oxide battery will lose 5% to 8% of its power a year just sitting unused. Another argument against trying to save battery power this way is that if the gears in the gear train sit stationary for a long time, the lubricants congeal.
