Glossary of Watch Terms
alarm: A beeping sound that notifies users of a pre-set time.
altimeter: A device that determines altitude based on changes in barometric pressure. An altimeter is often integrated into outdoor sport watches such as several models manufactured by Suunto Watches.
analog: A watch that uses hour and minute hands to show the time.
analog-digital display: A watch that uses analog (hour and minute hands) as well as digital (numbers) to show the time.
anti-magnetic: A watch that is not susceptible to magnetism, which is often found in televisions, speakers, refrigerators, and other electronics. Electronic watches are anti-magnetic; whereas, mechanical watches can be thrown off balance if they come in contact with a strong magnetic field.
automatic watch: A mechanical watch that is wound by the movements of the wearer's arm. Although quartz watches are more common, automatic watches are available from a number of manufacturers including Swiss Army.
automatic winding (or self winding): A watch with a mechanical movement that is wound by the motion of the wearer's arm, not by turning the winding stem. If it's not worn for a couple days, an automatic watch will need to be wound by hand to get it started again.
balance: On a mechanical watch, an oscillator regulates the speed of the movement.
balance spring (hair spring): On a mechanical watch, a very fine spring that returns the balance wheel to a neutral position.
balance wheel: On a mechanical watch, the part that oscillates, dividing time into equal segments.
battery reserve indicator (end-of-battery indicator): A feature on some battery-operated watches, this indicates when the battery is near the end of its life often by the second hand moving in two-second intervals.
bezel: The ring that surrounds the watch dial, or face. It's usually made of gold, gold plate or stainless steel.
bi-directional rotating bezel: A bezel that can be rotated either clockwise or counterclockwise, to be used for mathematical calculations, such as average speed, average distance, or elapsed time.
bracelet: A watch band made of links.
built-in illumination: A light on a watch that lets the wearer read it in the dark.
cabochon: A decorative stone that has been carved into a round shape.
calendar: A feature that shows the date. On some watches, it also shows the day of the week.
caliber: A term used to indicate the movement's shape, layout, or size.
cambered: Refers to a curved or arched dial or bezel.
case: The metal housing of a watch's parts.
caseback: The back side of a watch case (the side that lies against the skin).
case materials: The materials used in a watch case. Can be inexpensive cast metal or a solid metal, such as steel, gold, platinum, or titanium. Some watch cases have gold plating over brass.
chapter ring: The ring of figures and minute marks on the watch dial. The hour marks are sometimes called chapters.
chronograph: A watch with a built-in stopwatch function. The accuracy of the stopwatch can vary from 1/5th second to 1/100th second.
chronometer: A label given to Swiss-made watches that meet very high standards set by the Swiss Official Chronometer Control (COSC).
complications: Features added to a watch beyond basic timekeeping. These can include perpetual calendars, moonphase displays, alarms, repeating mechanisms, chronograph functions, power reserve indicators, and tourbillons.
cosmograph: Similar to a chronograph but with the tachymeter on the bezel instead of on the outer rim of the dial.
countdown timer: A function that keeps track of how much of a pre-set period of time has elapsed. May include a warning signal just before time runs out.
crown (stem) (pin): The button on the outside of the watch case used to set the time and date. In a mechanical watch the crown also winds the mainspring. If the crown screws into the case (called a screw-in or screw-down crown), it makes the watch watertight.
crystal: The transparent cover on a watch face made of glass crystal, synthetic sapphire or plastic. High-quality watches typically have a sapphire crystal, which is highly resistant to scratching or breaking.
day/date watch: A watch that indicates both the date and the day of the week.
day/night indicator: A colored or shaded band on a watch showing world time that indicates which time zones are in daylight and which in darkness.
deployment buckle: A buckle that pops open and fastens using hinged, often adjustable, extenders.
depth alarm: An alarm on a diver's watch that sounds when the wearer exceeds a pre-set depth.
depth sensor/depth meter: A device on a diver's watch that determines the wearer's depth based on water pressure.
dial: The watch face.
digital watch: A watch that shows the time through digits instead of a dial and hands. While digital watches fell out of favor following an initial wave of popularity after they were introduced in the 1970s and 1980s, they have fashionable once again with brands such as Nooka
direct-drive: A function that allows the second-hand to advance in intervals instead of a smooth sweep, allowing for more precise timekeeping.
dive watch: Dive watches are watches which have a minimum 200 meters of water resistance. In addition, they often have an elapsed time bezel, highly visible hands and markers and are constructed of materials that resist corrosive salt water.
dual timer: A watch that measures current local time as well as at least one other time zone.
Eco-Drive Technology: Solar power technology employed by Citizen Watches in most of its quartz models.
E Ink: Technology used in the display of Phosphor Watches which replicates the appearance of paper and ink. Also called Electronic Paper Display, or EDP, the technology is based on small capsules, about the diameter of a human hair filled with an equal number of negatively charged black particles and positively charged white particles floating in a clear liquid medium. The capsules are arranged in a thin sheet and laid over electronic circuitry which can form patterns of pixels. The patterns of pixel cause the black and white particles in each capsule to gravitate either to the top or the bottom of the capsule. What the the viewer sees on the watch's dial is an actual fluid ink display that can change instantly. But all you really need to know is it looks really cool..
elapsed-time rotating bezel: A graduated rotating bezel that keeps track of elapsed time. Turn the bezel to align the zero with the watch's seconds or minutes hand, and then check it to see how much time has passed (without needing to subtract).
