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.
Backlight
How to illuminate the clock face.
—
Luminescent coating. A variant used in pointer dials: the hands, and sometimes the scale, are coated with a “phosphorus” coating that glows in the dark. This method of backlighting is inexpensive and can be used even in low-cost models; in addition, it does not require batteries and is suitable even for mechanical watches. On the other hand, coverage is often not as effective as it should be. The fact is that for work it must be “charged” from the sun or another bright light source, and this “charge” is enough for an average of 5-6 hours, and already in the first couple of hours the brightness of the glow drops noticeably.
— Electronic.
Illumination based on LEDs or other miniature light sources. Usually, it does not work constantly, but turns on and off by pressing a special button; the exception is LED dials (see "Dial Type"). The main advantage of electronic backlighting is efficiency: it is guaranteed to be enough to view the image on the dial. In addition, such systems do not depend on external illumination, in contrast to the luminescent coatings described above. On the other hand, the lighting requires a battery to operate; therefore, this type of illumination is found exclusively in quartz watches (see “Mechanism type”).
— Luminescent coating / electronic. Systems that combine both types of illumination described above. This option is f
...ound mainly among models with combined dials: the hands are coated with a luminous coating, and the electronic backlight is intended mainly for displays and additional scales (and also as a backup option for the hands). The combined backlight is very convenient, however, such watches are somewhat more expensive.
— Tritium illumination. Illumination option found on premium pointer dials. Miniature flasks filled with tritium, a radioactive form of hydrogen, are responsible for the illumination in such models; from the inside, the surface of such flasks is covered with a phosphor, which glows under the influence of tritium radiation. Separately, we note that this radiation does not pose a danger to humans: it does not go beyond the bulb, and even inside its intensity is extremely low. Tritium illumination is expensive, but it is extremely convenient from a practical point of view: "flashlights" work constantly, without batteries and regardless of external lighting, and shine significantly brighter than a conventional luminescent coating. However due to the decay of tritium, they gradually lose their brightness, but this happens very slowly: it takes 12 years to reduce by half, and at least 20 years for the backlight to become useless.Strap colour
The main colour of the watch strap/bracelet.
The most popular shades nowadays are
stainless steel(the colour of most metal bracelets, not necessarily steel ones),
golden(bracelets made of gold and "gold"),
black(strap made of different materials, including rubber and nylon, as well as separate bracelets) and
brown(mostly leather straps). Other colour options include
beige,
white,
yellow,
green, camouflage (
military style),
red,
orange,
pink,
silver,
grey,
blue, and
purple.
In addition, some models of watches are equipped with two-tone straps. Most often,
white,
gold and
black are used as secondary colours, and this colour is specified after the main one — for example, “blue with white” or “stainless steel with gold”. If this paragraph lists several colours separated by commas — for example, "black, red, blue" — this means
...that the watch is either sold in several versions that differ in the colour of the strap, or comes with several interchangeable straps / bracelets of the corresponding colours at once. This nuance should be clarified separately.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.
