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.

Power source

The power source of a quartz watch (see "Movement type") — in other words, the type of power source used in it.

Battery. A miniature battery, usually in the form of a characteristic "pill"; used exclusively in quartz watches (see "Movement type"). The main disadvantage of this option can be called the need for replacement when the charge is exhausted; at the same time, almost all replaceable elements of miniature standard sizes used in wristwatches are produced only in the format of disposable batteries, without the possibility of recharging. On the other hand, they provide a long time of work, are inexpensive and are sold almost everywhere.

Solar battery. Power supply system consisting of a photocell and a built-in battery. The photocell generates electricity when exposed to bright light, and the battery stores this energy and feeds the watch mechanism. The convenience of such models lies in the fact that with the regular presence of solar (or at least bright artificial) light, the owner does not have to worry about the energy reserve. On the other hand, the photocell significantly affects the price, and if you constantly stay indoors or wear clothes with sleeves that cover your watch, it becomes practically useless. Therefore, this option has not received wide popularity, and it is worth paying attention to such models primarily because they are regularly and a lot outdoors and/or in...bright daylight.

— Autoquartz movement (“kinetic”). A kind of automatic winding (see above), used in quartz watches. This technology was originally released by Seiko under the name "Kinetic", but nowadays it can be found in other manufacturers. Anyway, such systems work similarly to mechanical self-winding — transforming the energy from the movement of the user's hand into the energy necessary for the operation of the mechanism. However, in this case, such a mechanism does not start the spring, but rotates a miniature generator that generates electricity. The resulting charge is stored in a special capacitor and used to operate the quartz movement. Models with such mechanisms are positioned as "quartz watches in which you do not need to change the battery", and in general it is so. At the same time, they have the same limitations as conventional self-winding devices — in particular, with a sedentary lifestyle, this technology is practically useless. Yes, these watches are quite expensive.

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.
