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.
The type of markup used on the main watch face. This parameter is relevant for models with hands (see "Dial Type"), while the type of marking is indicated only on the main scale — additional marks on the bezel are not taken into account (although markings on the additional world time dial may be taken into account).
This parameter does not affect the functionality of the watch, and the choice depends solely on the tastes of the owner. The main types of markings found in modern watches include
Arabic and
Roman numerals (which can be supplemented with marks),
a combination of these numbers, as well as the simplest
marks themselves. Here are the main features of these options and their combinations:
— Arabic. Dials that have marks only in the form of Arabic numerals — that is, standard modern numbers "1", "2", etc. In this way, both all divisions of the dial, and only some of them (for example, 3, 6, 9 and 12 o'clock). However, anyway, there are no other types of marks in such watches.
— Roman. Dials that are marked only in the form of Roman numerals — combinations of the symbols I, V, X. This marking gives the watch a peculiar style, but it can take some getting used to — and therefore is less common than Arabic numerals. Again, in this case we are talking about dials that do not carry any other designations, excep
...t for numbers of this type.
— Tags. Minimalistic design, in which the divisions on the dial are indicated only by a label, without a signature. Most often, marks are applied to all twelve hours; exceptions to this rule are possible, but they are rare nowadays. It should be noted that such a design can be found both in classic watches with minimal functionality and in advanced models with extensive features: in the first case, the marks give the product a neat appearance, in the second, they save space on the dial for additional scales and markings. Theoretically, such markup is not as convenient as notation with numbers; however, almost all dials in modern wristwatches use a 12-hour scale with a standard location of marks, so with a little habit you can completely do without numbers — the position of the mark on the scale already carries enough information.
— Arabic + Roman. Dials that combine both types of numbers described above at once (sometimes also with marks; in this case, the presence of marks is not specified). The most popular type of watch with this feature is the world clock (see "Features and Features"), where one dial is marked with Arabic numerals and the other with Roman numerals. There is also a combination of these symbols on the same scale — for example, when 3 and 9 hours are indicated by ordinary numerals, and 6 and 12 by Roman numerals. However, neither one nor the other variant received special distribution.
— Labels + Arabic. Dials, in which part of the markings are applied with Arabic numerals, part with marks (for both, see above). Moreover, the ratio of both can be different: for example, in some models there is only one digit (usually "12"); in others, key positions "3", "6", "9" and "12" are designated by numbers; thirdly, part of the dial is occupied by a display, near which the numbers simply do not fit and you have to manage with marks, etc.
— Marks + Roman. The dials, in which part of the markings are applied with marks, part with Roman numerals. This markup method is generally similar to the “labels + Arabic” option described above (and can also provide different design options).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.
