Accuracy
The accuracy of the rate is usually determined by the largest error — the deviation from the reference time, which can occur in a month when the watch is constantly running in normal mode. Accordingly, the smaller the number in this paragraph, the more accurate the clock. In addition, the accuracy of the movement is a kind of status indicator: if the error exceeds the values stated in the characteristics, this may indicate a malfunction in the mechanism.
If the accuracy indicators are the same both in advance and in lag, one number is indicated in the characteristics — for example, 30 sec / month (i.e. +/-30 sec / month); however, many mechanisms have unequal deviations, for example -15/+25 sec/month. Also note that this parameter is relevant only for quartz watches (see “Movement type”): in mechanical models, the accuracy of the rate is noticeably lower, it is measured in seconds not per month, but per day.
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.
