Comparison Citizen NY0040-09EE vs Seiko SNZG15K1

Watch models designed for left-handed people. The key feature is the location of the crown, which is not traditionally on the right, but on the left side of the case.

The number of stones provided in the design of the watch.

This parameter is relevant for models that have arrows and corresponding moving parts in the "stuffing" (wheels, gears, etc.). The stones in this case are, in fact, a specific kind of bearings used to fasten rotating parts. "Stones" are made from synthetic minerals (for example, artificial sapphires). They provide slightly less friction than traditional metal bearings, and most importantly, they are more reliable and less prone to wear, which accordingly affects the durability of the entire mechanism. However, it is worth noting here that these advantages are relevant mainly for mechanical watches (see “Mechanism type”), quartz models in this sense are not so demanding on bearings.

It is believed that the more stones, the better, but here it is worth considering the functionality of the device. So, for a watch with a central second hand, 16 jewels are considered sufficient, with a side one - 17, but if there are additional functions (calendar, days of the week, etc.), this number can increase accordingly. In addition, the presence of 40 or more stones is often not so much a real necessity as a publicity stunt.

A caliber can be described as the type of movement used in a watch. It is expensive and impractical to design a unique movement for each watch model, so most manufacturers often use the same movement in different watch models, sometimes with significantly different designs. The term "caliber" is due to the fact that initially the type of movement was designated by a number (in inch lines) corresponding to its largest size; however, today unique names or alphanumeric indices that are not directly related to sizes are widely used.

Knowing the name of the caliber on which the watch you are interested in is built, you can, if desired, find more detailed information about the mechanism and determine how its characteristics meet your requirements.

The amount of time that the watch is able to operate normally without winding the spring or changing/recharging the battery (for more details, see "Power source"). Modern mechanical watches (see “Movement type”) have a standard power reserve of 40+/-5 hours. However, this parameter is usually indicated for the simplest mode of operation, without the use of additional functions such as a chronograph(see “Functions / Capabilities” ), which also “eat up” the plant. Thus, such a watch is supposed to be wound every day, but nothing will happen if you miss the usual time and remember to wind it a few hours later than usual.

In turn, for quartz watches, the power reserve is often not indicated in the specifications. This is due to the fact that this parameter, firstly, is quite large compared to mechanical models (it would be measured in tens of days rather than hours), and secondly, it strongly depends on a number of external factors (for example, the quality of the next batteries). Therefore, it is very difficult, if not impossible, to reliably determine the power reserve in such cases.

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 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.

The rotating bezel is a swivel ring around the dial, with marks applied to it (ring).

Usually the bezel scale is similar to the minute/second scale of the dial, it is marked from 0 to 60, most often with marks every 5 or every 10 minutes (seconds). In such cases, this function is a somewhat simplified analogue of the timer or stopwatch / chronograph used in watches with analogue dials. To work in the stopwatch mode, you need to align the zero on the bezel with the position of the second or minute hand (depending on how long the period needs to be detected), and at the end of the measurement, look at what division on the bezel this hand has reached. To work in the timer mode, zero on the rotary scale is set at the end of the countdown, and the user can only monitor whether the arrow has reached zero. Thus, you can turn the watch into a timer or stopwatch mode with just one turn of the ring — it's faster and more convenient than digging into the settings. Such features are appreciated, in particular, by scuba divers who use a timer to control air supplies; at the same time, in diving watches, the rotation mechanism is often made one-sided, so that the bezel cannot be accidentally turned in the direction of increasing the remaining time.

There are other types of rotating bezels — for example, in the form of a scale with cardinal points used in watches with a compass.

The presence of a case back made of transparent material in the design of the watch, allowing you to see the mechanism.

This element does not play a practical role, but it gives the watch an original appearance. Note that the transparent cover can be combined with a Skeleton, open balance (see below) and/or a transparent case (see above) case. The key differences between these features are that Skeleton and the open balance allow you to see the movement from the front, while the transparent case can be seen through, but the movement may not be visible.

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.
