Dial colour

Clock face background colour. Indicated for models with pointer or combination dials (see "Dial type"); in purely electronic models, usually, either a grey substrate (for conventional LCDs) or a dark base (for LEDs) is used.

The most popular in modern watches are black, white, silver and blue dials. However, in addition to this, other shades can be found on the market — in particular, beige, yellow, green, golden, brown, red, orange, pink, grey and purple. A special case are watches with chameleon glasses (see below).

Some models are available in several colour options, in such cases these options are listed separated by commas — for example, "white, red, silver." If the dial is painted simultaneously in 2 or 3 colours, they are indicated as a combination — for example, "white with red" or "white with yellow and red". And multi-coloured models include models in which more than 3 colours are used for the dial.

Colour

The main colour of the watch case.

Modern watches are quite diverse in colour options. The most widespread models are in shades of " stainless steel ", golden and black ; however, in addition to this, on the market you can find, in particular, white, yellow, green, brown, red, orange, pink, silver, grey, blue and purple cases.

In general, the colour of the case is a fairly obvious parameter; Let's note only some of the nuances associated with marking:

— Multi-coloured models include models in which there is no clearly defined primary colour. If there is such a colour, it is indicated in the characteristics. And for two-tone cases, an additional colour can be specified, for example, "stainless steel with gold " or "black with blue "

— Silver, among other things, are plastic cases without additional coloring.

— "Stainless steel" in this case is a colour, not a material; other metals (e.g. alumin...ium and titanium) that are not complemented by PVD coating (see “Case Coating”) may have this shade. And the cases of gold watches, in turn, are not necessarily made of gold — red and white gold are also used in jewelry.

— Camouflage coloring is indicated separately — such watches are designated as "military", and here, again, the main shade of the coloring is given. However, not every military model has camouflage on the body; see below for details.

Screw-down crown

The crown (or the crown of the hands, if the watch is quartz), which is fixed on a special thread during non-working hours. Accordingly, for use for its main purpose, such a head must first be unscrewed, and only then it can be rotated.
The screw design serves two main functions. Firstly, it does not allow the head to move in case of accidental contact with surrounding objects (whereas a conventional head can be hooked and rotated in case of an unsuccessful hand movement, knocking down the position of the arrows). Secondly, the head fixed on the thread plays the role of a protective cap covering the gap between the axle and the body - this improves moisture protection.

Band width

The nominal width of the strap/bracelet supplied with the watch. It is indicated by the width of the fasteners for installing the strap on the case.

This parameter does not play a special role when choosing a watch, but it is key when choosing a third-party strap / bracelet — for example, to replace a broken one. If the width of such an accessory does not correspond to the characteristics of the watch, it will be very difficult to install it at best, and most often it will be impossible at all.

Also note that in most cases this width is about half the width of the watch itself (see "Diameter / Width"). For example, 32 mm watches are usually equipped with 14 mm straps, and for 43 mm cases this width is 22 mm. However, there is no strict dependence here, and models with the same case sizes may differ in the size of straps/bracelets.
