Automatic Watch Care and Service

An automatic watch is a mechanical watch with a rotor. The rotor is a weight that swings as you move. That swing winds the mainspring. The spring lets its energy out slowly through a train of gears, and a balance wheel with a hairspring meters the time. No battery is doing the counting. If you do not wear the watch, the rotor does not swing, the spring runs down, and the hands stop. That stop is the normal end of the power reserve. It is not, by itself, a failure.

Some automatics can also be wound by turning the crown. Some should not be, because the winding works only one way or the crown is not built for it. If you do not know, do not grind the crown back and forth to "test" it. A watchmaker can tell you in a minute whether hand-winding is part of that movement. Forcing a crown past its stop is a bent stem, which is a real failure, unlike a watch that simply ran down.

The product file for this shop has no watches. Categories in it are rings, bracelets, necklaces, pendants, earrings and chains. Care instructions below are general horology, not a service menu and not a listing. If you came here to buy diamonds set in gold, start at the collections or at custom jewelry.

Pick the watch up, note the time, and if the crown is meant to wind, give it a gentle wind until you feel resistance. Do not force past resistance. Then set the time the way that watch is designed to be set, which usually means the crown pulled to a set position, never cranked while it is only pushed in. Wear it. If the hands start and keep a steady rate the next day, you had an empty spring.

A watch winder is a box that keeps the rotor moving while you are not wearing the watch. It is useful if you rotate several automatics and do not want to set them every Monday. It is unnecessary if you wear one watch most days. A winder is not a cure for a watch that gains minutes or stops while it is on your wrist. That pattern is a movement problem, and the next step is a watchmaker, not a more expensive box.

Do not shake a stopped watch hard to "get it going." The rotor can wind a healthy watch from normal wear. Whipping the case is how a balance staff gets bent. If a gentle wind and a day on the wrist do nothing, stop home experiments. We do not take watches in for that diagnosis. The catalog has nowhere to put one.

The hairspring is a thin coil. A strong magnet can make the coils stick, and a stuck hairspring usually makes a mechanical watch run fast, sometimes wildly fast. Speakers, magnetic clasps on bags and tablets, and some phone cases are ordinary sources. If the watch suddenly gains a lot of time after sitting next to one of those, magnetism is the first suspect. A watchmaker demagnetizes the movement with a small tool made for it. Kitchen experiments with other magnets are how you magnetize it worse.

Knocks are the other everyday killer. Dropping a watch onto tile can break or bend the balance staff even when the crystal survives. The crystal is not a crash sensor. If the watch stops after a drop, or the rotor sounds like it is scraping, do not keep wearing it to "see if it clears up." Metal on metal inside a movement makes expensive dust. Again, that visit is a watchmaker's visit, not a jewelry-counter visit.

Heat and cold change rate a little on every mechanical watch. A certified chronometer, under the COSC standard published for mechanical movements, is tested to stay within minus 4 to plus 6 seconds per day, in set positions and temperatures, usually on the movement before the watch is cased. That is a lab result for watches that actually went through the test. It is not a promise that every automatic on earth runs that close, and it is not a promise about a watch that has been magnetized or dropped. Most automatics are not chronometers. Judge yours by whether its rate is steady, not by a slogan on a forum.

A water rating is a statement about the watch when the gaskets were new and the crown was closed, under test conditions. Gaskets dry out. A crown that is not fully pushed or screwed down is an open door. A rating printed years ago is not a current test. Do not shower, swim or press buttons underwater because a dial still says a depth. Condensation under the crystal, a faint fog that was not there yesterday, means moisture is inside. Stop wearing it and get it to a watchmaker before rust starts on the steel parts.

Do not pull the crown in a pool, a sink or a steamy bathroom. Setting the time can wait until the watch is dry and cool. Do not use the bracelet sizing moment as an excuse to rinse the whole head in the sink. Pins and movements do not need a bath.

Jewelry has a different water problem, and it is the one this shop can speak about with products behind it. Gold chains and diamond pieces have their own cleaning limits, covered in how to clean a gold chain and how to clean diamond jewelry. A watch with stones glued or paved onto the bezel should not be thrown into an ultrasonic cleaner because a jewelry article said ultrasonics are fine. Stones added after the factory are often held in a way the original case was not built for. When you do not know how they are held, you do not bathe the watch.

Diamonds on a bezel or a bracelet can be part of the way the watch left the factory, or they can be added later. Those are different objects. A later stone job is not a factory piece, even if the dial still carries a name. Care follows the weaker of the two: the movement's rules, and the stone setting's rules. Prongs and beads that were added later can be thinner than a jewelry shop would use on a ring. Catching them on a sleeve can lift a stone. Check for dark holes where a stone used to be, in normal light, once a month.

Cleaning is a soft brush and a little mild soap on the metal, with the crown closed, and the watch not soaked if you are unsure of the gaskets. Dry it. Do not boil it. Do not use a jewelry pickle, a harsh dip, or a paste that cuts metal. If the stones are laboratory-grown or natural, the care is about the setting, not the origin. Origin still has to be disclosed when someone sells the stones. The FTC wants laboratory-grown diamonds named in clear words. GIA's point is that the crystal can match natural diamond while the growth history does not. None of that makes a paved bezel waterproof.

This shop sells diamond jewelry without a watch attached: lab diamond bracelets up to a 26.6 carat piece at $9,000, natural diamond pendants from $5,800 to $9,500, earrings to $4,115. Those are the pieces we can price. A paved watch is not among them. Read how to clean iced-out jewelry for the jewelry version, and iced-out watches in Miami only as local reading, not as a claim that a watch is on our shelf.

A mechanical watch needs a watchmaker when the rate is no longer steady, when moisture appears, when a drop changed the sound of the rotor, or when the maker's own guidance says it is due. We do not publish an interval in years, because intervals differ and this catalog does not include the watches. Follow the guidance that came with the watch if you have it. If you do not, a watchmaker's inspection beats a number copied from a stranger's post.

People sometimes expect a jewelry counter to work on a watch clasp. We are not publishing a watch-bracelet service. Link sizing, as a method you can do or hand to a watchmaker, is on how to size a watch bracelet. Clasp types on chains we do sell are on chain clasp types and lobster versus box clasp. Those pages are about necklaces and bracelets in gold, not about a folding watch clasp.

If the object in your hand is actually a gold chain that needs a cleaning routine, you are in the right shop and the wrong article. Go to the cleaning guide and the catalog. If the object is a watch, you are in the right article and the wrong counter.

Wear it or wind it the way that movement allows, so the stop you see is not a surprise. Keep it off magnetic clasps and off the back of a phone. Take it off for anything that bangs the wrist. Close the crown. Skip the water unless you have a fresh reason to trust the gaskets. Look at stone settings in daylight if the piece has stones. Keep the spare links in the box. Write down the day you last had a watchmaker look at it.

None of that routine requires a brand name, a forum argument, or a winder the size of a microwave. It requires knowing that an automatic is a spring, not a battery, and that a spring runs out. Quartz watches are a different machine. The comparison is on automatic versus quartz.

For anything we can actually sell, the rules are the jewelry rules. Insured shipping. A 7-day window for a manufacturing defect. No refunds. All sales final. The showroom is at 7900 NW 27th Ave, Unit 506, Miami FL 33147, phone 954-504-5640. You will find chains from $290 to $4,960 and rings from $495 to $8,680. You will not find a watch in that file. Shop the watch guides for reading, and the collections for metal you can take home.
