This is usually at the 3 ‘0’ Clock position on the case, also known as the winder or button. Most occasions it pulls straight out to operate the hands and in some cases the date, but on some models like diving watches it unscrews from the case before it can be pulled out, this is to ensure water resistance and no dust getting into the movement, on models such as the Rolex Submariner, Breitling SuperOcean, Omega Seamasters.

Tag Monaco GulfChronograph
A timing device (stop watch) with one to four small dials within the main one.
This is not to be confused with Chronometer.

Crystal
This is referring to the glass, it can be Mineral, Sapphire, or plastic (this is generally on older watches) sometimes called Hesalite.

Sapphire crystals are very hard and difficult to scratch, mineral glass tends to be present in less expensive watches.

Movement - staffordhall.comMovement
The movement refers to workings inside, which can be mechanical hand wound which was the first type in watches, automatic which is also mechanical but has a auto weight to self wind the watch when worn. Quartz is a battery movement, these type of movements are accurate within seconds a year, where as Mechanicals can gain or loose several seconds a day which is normal.

Solar and Kinetic (not the same as automatic) an auto weight powers a quartz type movement, which stores power in a Capacitor.

Movements also have a number referring to the type this is called “Calibre” so the Omega movement to the upper left is a 321 Calibre.

Deville 18ct - staffordhall.comCases
Watch cases can be made of lots of different materials such as Steel, usually stainless, Gold of all quality, Platinum, Silver, Brass, Plastic, and in modern days Ceramic, and Titanium.
Sometimes watches consist of two materials or more, referred to as 2 colour or Bi Colour watches, a very popular combination is steel and gold.
A case most of time is in two parts, caseback and main case, the caseback can be snapped on, screwed, or have several little screws holding it on.
There are also one piece cases in which the movement is fitted into the case then the glass fitted after, like the Breilting Top Time.

Omega - staffordhall.comBezel
