Glass material

The material of the transparent coating covering the dial.

Plastic. Transparent plastic (also known as "plexiglass", also known as "organic glass") is considered the simplest option and is found mainly in models of the initial and middle price range, mainly sports and tourist specialization. This material is lightweight, inexpensive, and also tolerates shocks and falls well: with a strong impact, it will crack rather than break, and plastic fragments are much safer than glass ones. These properties are indispensable for shockproof watches. On the other hand, plastic is very sensitive to scratches and tends to become cloudy quickly due to scratches; and in general it gets dirty more easily than glass.

Mineral. Mineral in this case means ordinary, widespread glass — like the one used in windows. It favorably differs from plastic in high hardness: to scratch such material, you need to make considerable efforts. As a result, mineral glass varieties do not become cloudy and remain transparent for almost the entire life of the watch. Among the shortcomings, brittleness can be noted: upon impact, the glass surface can shatter into fragments. On the other hand, even for ordinary glass, such a blow should be quite strong; in addition, manufacturers often use various design solutions (“dial” recessed into the case, tempered glass, etc.) in order to reduce the ri...sk of such an accident to an absolute minimum. Thanks to all this, mineral glass has become widespread today in all types and price categories of watches.

Sapphire. Glass made of artificially grown sapphire (transparent corundum — aluminium oxide). The main advantage of this material is the highest scratch resistance: such a surface can only be scratched with a diamond or a material similar in hardness to it. On the other hand, sapphire crystals are not cheap, but they do not withstand shocks well and are relatively unsuitable for "protected" watches. As a result, this material is found mainly in rather expensive models designed for everyday use (although there are exceptions).

Diameter (width)

The nominal size of a watch case in diameter (for round cases) or width (for other options, see "Case Shape"). In the most miniature modern models, this size is 21 – 25 mm or even less, among the largest there are cases of 46 – 50 mm and even larger.

Larger watches are more convenient in the sense that the dial readings are better visible on them, and it is easier to provide various additional functions in the design. On the other hand, small watches look neater and create less discomfort directly when worn. In addition, female models (see "Gender") are traditionally made more miniature than male ones. So the choice for this indicator depends mainly on the intended specifics of the application: for example, large cases are best suited for outdoor activities and tourism, about 41 – 45 mm in size, for household wear (regardless of gender) — about 31 – 35 mm, and as an accessory to an evening dress, a small watch of 30 mm or less would be more appropriate.

Also note that the size of a compatible strap/bracelet is associated with this indicator — see "Strap Width" for details.

Thickness

The thickness of the watch case. A fairly obvious parameter; we only note that nowadays it is customary to attribute watches with a thickness of less than 7 mm to ultra-thin models. This design has both aesthetic and quite practical meaning — a thin watch will be useful for those who wear narrow sleeves with tight-fitting cuffs.

Weight

Total weight of the watch. As a rule, it is indicated taking into account the complete strap/bracelet.

The lightest modern watch weighs no more than 50 g. The most popular models weigh 50 - 100 g, and weight more than 150 g most often means not only a large, but also a fairly advanced device, usually for sports and tourism purposes.

Both light and heavy weight have their advantages: light watches create minimal inconvenience when worn, while massive watches are subconsciously perceived as a solid and reliable device.
