Like any other science, horology — the study of timekeeping, clocks and watches — has its own ultra-specialized vocabulary, which can be intimidating to the uninitiated. To help newcomers to the watch world, especially if you are a huge fan of watches, here’s and list and an explanation of ten essential terms that you must know when you go watch shopping.
A small opening on the dial providing an additional indication (usually month, day or moonphase).
This ring-shaped piece surrounds the dial of the watch and joins the case to the crystal. Though generally stationary, some bezels can be rotated by hand, as is the case on diving watches, which are traditionally equipped with rotating bezels with markings to help divers calculate the amount of time needed to return to the surface.
This usually round, box-like component can be considered as the shell of the watch. The case contains the movement, dial and hands.
This term refers to a watch’s additional functions outside of its standard ability to show hours and minutes. Chronographs with stop and start functions, moonphase displays, date indicators and chiming mechanisms are some of the most common complications found on watches.
This complication allows the wearer to measure short stretches of time, for example to time a lap at the race track, using a separate timer. Chronograph functions have become especially popular on men’s watches over the past century.
Sometimes also called a winder, this is the small dial that allows the wearer to wind the movement and set the time.
Also called the face, this is the disk where the time, date and any other additional indications are displayed.
These are the small projections on the case used to attach the strap or bracelet.
This is the complex ensemble of parts that make the watch run, a little like the engine in a car. There are three main types: battery-powered quartz movements, self-winding mechanical movements or hand-wound mechanical movements.
Second time-zone indicator
Among the easier terms to decipher, this complication indicates the time in a second time zone thanks to an additional hand or a separate dial.
