This parameter determines, first of all, the appearance of the clock, and only then — the functionality. In addition, the wearing of "men's" and "women's" watches by adults is related solely to the rules of style and social norms, and not to the technical characteristics of different models.
—
Men's. Men's watches have a rather large case and a relatively discreet, dim design — which, however, can be different, from strict classics with a single scale on the dial to "hi-tech" with an abundance of additional features.
—
Women's. This type of watch stands out primarily for its original design, more varied and bright than in men's models; this applies not only to the watch itself, but also to complete bracelets / straps. A fairly large number of such models are designed to play the role of not only a wrist chronometer, but also a fashion accessory. In addition, they are generally smaller and more elegant, and even rather large women's watches weigh less than men's watches of the same size.
—
Unisex. A watch with a neutral (in terms of gender) design, without pronounced details that would characterize it as masculine or feminine. In general, the design of such watches is often quite bright and original, many unisex models are designed for a youth audience, lovers of the original style, etc.

Baby. Watches
...designed for children have two main features. One of them is a characteristic design: in bright colours, often in the style of popular cartoons or comics. The second is that regular bracelets or straps are designed for a small child's hand and are equipped with the simplest clasps so that the small owner does not have problems with putting on / taking off. Also note that children's watches are distinguished by relatively simple functionality — you will not find special features like world time, chronograph, barometer, etc. in them (see "Features").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.
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.
