GLOSSARY OF WATCH TERMS
Finding your private label or custom made watch can be difficult when you encounter the number of terms that are used to describe watch functions and parts. To help you we’ve come up with a list of some of the most used terms by us.
A subdial on a chronograph that can time periods of up to 12 hours.
A subdial on a chronograph that can time periods of up to 30 minutes.
A watch with a dial, hands, and numbers or markers that present a total display of 12-hour time span. Analog digital refers to a watch that has both a digital display and hands of a conventional watch.
Anti reflex coating
AR (Anti Reflective) Coating is a superficial glass treatment assuring the dispersion of reflected light. Anti Reflective coating is designed to reduce light reflection by optical interference. An Anti Reflective coating bends incoming light wavelengths and eventually one wavelength cancels out another. Also, reflection is reduced to < .5% per side and transmission is increased to over + 98% depending on the substrate and its thickness.
Small opening. The dials of some watches have apertures in which certain indications are given (e.g. the date, the hour, etc).
Process of fitting together the components of a movement.
A mechanical movement that requires no winding because the rotor, part of the automatic mechanism, winds the mainspring every time you move your hand. Most automatics have up to 36 hours of reserve power. Mechanical movements are accurate within one minute each day. If an automatic watch is not worn for a day or two, it will wind down and stopped working.
Energy source in which electrical energy is generated through direct
transformation of chemical energy.
The ring which surrounds the watch dial (or face).
Bi-directional rotating Bezel
A bezel that can be turned either clockwise or counter clockwise. Rotating bezels can be used to measure elapsed times, or read second or third time zones.
A type of watch band made of elements that resemble links.
A feature that shows the date. Day, month, and moon-phases are often
shown additionally. There are several types of calendar watches. Most
calendar watches show the information digitally through an aperture on the watch face and some watches show the information on subdials.
Synonym for size and form of the movement. The term is used to indicate the movement’s shape, layout, or size.
A watch case has generally 3 parts. The bezel (which holds the crystal),
the case middle part (which contains the movement and fitted the
strap/bracelet) and the case back which is either snapped or screwed on. Stainless steel is the most typical metal used but titanium, gold, silver, and platinum can also be used. Less expensive watches are usually made of brass and plated with gold or silver.
The back side of a watch case that lies against the skin. May be transparent to allow viewing of the inner workings of the watch or be solid. You can engrave case backs with your name, company logo, numbering, water-resistance, case metal content and other details.
A chronograph is a mechanism for measuring short time periods
independently of the normal timekeeping function.
Swiss-made movements which meet very high standards set by the Swiss Official Chronometer Control. A chronometer is a mechanical movement of the very highest quality. Movements are usually tested in various positions and at various temperatures. COSC = Contrôle Officiel Suisse des Chronomètres (Official Swiss Chronometer Testing Institute).
The company was originally founded as Shokosha Watch Research Institute in 1918 and is currently known as the manufacturer of Cincom precision lathe machine tools as well as Citizen watches. The trade name originated from a pocket watch Citizen sold in 1924. It is one of the world’s largest producers of watches and movements.
Chronograph counter. Mechanism that shows, on a dial, the number of
revolutions of the chronograph-hand, i.e. 1/10th or 1/100th seconds,
minutes, and hours.
A function that lets the wearer keep track of how much of a pre-set period of time has elapsed. Some countdown timers sound a warning signal a few seconds before time runs out. These are useful in events such as yacht races, where the sailor must maneuver the boat into position before the start of a race.
The crown is used for winding up a mechanical watch or for setting the
hands to the correct time. Also you can use setting the date in the case of calendar equipped watches.
The crystal is the transparent cover over the dial. There are various
materials used like plastic, mineral glass or sapphire.
Watches made according to the specifications of the buyer. Design your own brand name watch from scratch.
The date is showing through an aperture in the dial. Typically at the 3
o’clock or 6 o’clock position.
Apertures which display both the date of the month and the day of the
A type of buckle that pops open and fastens using hinged, often adjustable, extenders. A deployment buckle is easier to put on and remove and is more comfortable on the wrist.
The face of a watch showing the time, your company logo or brand name and other functions that may be displayed by hands, markers, discs, or through windows. In high-end watches the numerals, indices and surface designs are applied as separate elements. In less expensive watches, they may be simply printed on the dial.
A watch that shows the time by numbers on an LCD or LED display.
A watch that measures current local time as well as at least one other time zone. The additional time element may come from a twin dial, extra hand, subdials, or other means.
Having a moulded or carved company logo, your brand name, design or text on the surface so that it is raised above the surface in low relief.
(End of Life) Some battery operated watches have a feature that indicates when the battery is approaching the end of its life. This is indicated by the second hand jumping every 4 seconds, or in a digital watch, by a flashing display.

The inner mechanism of the watch that keeps time and moves the watch’s hand, calendar, etc. Movements are either mechanical or quartz.
Pad printing (also called tampography)
A printing process that can transfer your 2-D company logo or your brand name onto a 3-D object. This is accomplished using an indirect offset printing process that involves an image being transferred from the cliché via a silicone pad onto a substrate. Pad printing is used for printing on otherwise difficult to print on products in many industries including medical, automotive, promotional, watch industry, apparel and electronic objects.

A movement which allows a watch to keep time without being wound. it uses an electric current to cause a quartz oscillator to vibrate, normally 32’768 Hz per second. The power comes from a battery that must be replaced about every 1.5 years. For our private label watches we only use the best quartz movements made in Japan or Switzerland.
Ronda, the second largest Swiss movement manufacturer (after ETA) produces about 32 million movements a year. Many companies, considereded “medium to high end” use their calibers (Maurice Lacroix, Raymond Weil, Swiss Army,Wenger etc.) There has been a consistent effort from Ronda to become alternatives to ETA when supplying complicated quartz movements. The finish of Ronda STARTECH calibers is on par with the best of ETA.

Rotating Bezel (turning bezel)
A bezel (the ring surrounding the watch face) that can be turned. Different types of rotating bezels perform different timekeeping and mathematical functions.
In an automatically winding wristwatch, the rotor is winding the mainspring by the movements of the wrist. It is a segment made of heavy metal, which turns freely in both directions.
In watchmaking, jewels made of synthetic ruby. They are used in sensitive parts of the machinery to reduce friction. They helping the watch stay accurate and last longer.
A crystal made of synthetic sapphire. It possesses the characters of high hardness, scratch resistant and light transmittance performance.

They are a successful leader in the watch industry with a considerable volume of production. Sellita combines the watchmakers’ craftsmanship with rigid quality standards. This has been the key idea of their work and it is the reason for their dynamic development. Over the years, this philosophy has enabled Sellita to provide mechanical movements to the mid-range as well as top-of-the-end markets and watch brands. It is predicted that Sellita will step in ETA’s shoes and start providing movements on a mass scale in the next few years.
Small second hand
A hand which showing the seconds on a sub-dial.
Split Seconds Hand
Actually two hands, one a flyback hand the other a regular chronograph hand. When the wearer starts the chronograph, both hands move together. To time laps or different finishing times, the wearer can stop the flyback hand independently while the regular chronograph hand keeps moving.
Stainless Steel 316L
An extremely durable metal alloy that is virtually immune to rust, discoloration and corrosion. Stainless steel is used for jewelry and watches with 316L being the type commonly used for such applications. It can be re-finished by any jeweler and will not oxidize or turn black.
Stainless steel finishes
The following finish can then applied to achieve the desired aesthetic appearance.
1. Brushed finish
2. Satin finish
3. Matte finish (brushed but smoother than No.1)
5. Physical Vapor Deposition (PVD) This is a special treatment for hardens the surface. (Usually comes in black color)
The strap fixed the watch on the wrist. Can be made of leather, rubber,
textile or metal.
A white and highly reflective precious metal. Sterling silver refers to silver that is 92.5 percent pure, which should be stamped on the metal, sometimes accompanied by the initials of the designer or the country of orgin as a hallmark. Although less durable than stainless steel and other precious metals, sterling silver is often employed in watches that coordinate or look like sterling silver jewelry. A protective coating may be added to prevent tarnishing.
Sweep seconds hand
A seconds hand that is mounted in the center of the watch dial.
Throughout the world the reputation of Swiss made watches is unrivalled. Know-how, impeccable quality, aesthetic prowess, technical innovation: the indication Swiss made reflects all this, and much more.
You can find a tachymeter on some chronograph watches. This is a
feature used to measuring speed per hour on a scale on the dial or on the bezel. The distance based on 1000 meters.
The “space age” metal, often used with a silver-gray appearance. Because it is 30 percent stronger and nearly 50 percent lighter than steel it has been increasingly used in watchmaking, especially sport watch styles. Its resistance to salt water corrosion makes it particularly
useful in diver’s watches. Since it can be scratched fairly easy, some manufacturers use a patented-coating to resist scratching. Hypoallergenic.
A watch shapped like a barrel, with two convex sides.
A device in a mechanical watch that eliminates timekeeping errors cause by the slight difference in the rates at which a watch runs in the horizontal and vertical positions. The tourbillon consist of round carriage, or cage, holding the escapement and the balance. It rotates continously at the rate of once per minute.
An isotope of hydrogen that is used to activate the luminous dots or indices on a watch dial. The radioactivity released in this process is too slight to pose a health risk.
A watch that combines two metals, usually yellow gold and stainless steel in the case of fine watches.
Uni-directional rotating bezel
A bezel that turns only one way – counterclockwise. Particularly useful for divers, because the bezel cannot accidentally rotate it in the wrong
direction and the diver is on the side of safety.
Movement of a pendulum or other oscillating element, limited by two consecutive extreme positions. The balance of a mechanical watch generally makes five or six vibrations per second (i.e. 18,000 or 21,600 per hour), but that of a high-frequency watch may make seven, eight or even ten vibrations per second (i.e. 25,200, 28,800 or 36, 000 per hour).
