— Brass. Inexpensive material used mainly in watches of the corresponding price category. The composition is an alloy based on copper and zinc. Brass bodies have a pleasant golden colour, but their resistance to corrosion is usually very low. Because of this, such watches darken very quickly, and oxides can stain the wearer's skin and even lead to irritation. To correct the situation, various protective coatings, stainless steel covers, etc. can be used; however, even these measures are not able to completely eliminate this drawback.

Stainless steel. Inexpensive and at the same time very practical material found in watches of all price categories. "Stainless steel" looks good, perfectly resists corrosion and scratches, retains its presentation for a long time and does not cause allergies. However it has a rather large weight, but for many users, the massiveness of the watch is an advantage, not a disadvantage.
—
Titan. Premium material used in watches of the corresponding price level. Titanium alloys combine lightness and high strength, in addition, they are less thermally conductive than steel, due to which they do not “cool” the hand. They are practically not subject to corrosion, do not require protective coatings and are hypoallergenic. On the other hand, such cases are quite sensitive to scratches.

Plastic. Common features of all types o
...f plastic are ease of processing, relatively low cost, low weight, hypoallergenicity, moisture resistance and poor thermal conductivity. For a number of reasons, this material is considered optimal primarily for sports watches, including “diving” (waterproof) watches. At the same time, it should be noted that many types of plastic are used in modern watches, including high-strength varieties that are not inferior in reliability to steel. Therefore, this material is found in all price categories, from low-cost to top; The quality of the case is usually directly related to the cost of the watch.
— Aluminium. "Watch metal", considered a little more advanced than stainless steel. The aluminium alloy is also durable, resistant to corrosion and scratches, and has a solid appearance. At the same time, on the one hand, it is noticeably lighter, on the other hand, it is more expensive.
— Copper. By itself, copper has a pleasant reddish-brown tint, but it does not tolerate prolonged contact with the skin — the surface begins to oxidize, which leads not only to skin contamination, but also to irritation. Therefore, this material is usually used in combination with protective coatings. In fact, it has no advantages over the same "stainless steel", and therefore it is used quite rarely — and not so much for practical or even aesthetic reasons, but in order to distinguish watches from other models.
— Carbon. Composite material, in fact, is high-quality plastic: carbon fiber strands filled with polymer filler. Carbon is notable for its combination of low weight with very high strength; in general, it surpasses even steel in reliability; at the same time, it has many advantages of plastic, such as moisture resistance and low thermal conductivity. The disadvantage of such housings, in addition to high cost, is sensitivity to point impacts.
— Ceramics. Ceramics are various materials obtained by sintering and firing at high temperatures. Watch cases are usually made of high-quality ceramics, which are distinguished by their solid appearance and very high scratch resistance, and they cost accordingly. At the same time, they are quite sensitive to shocks, so a ceramic case is often combined with a stainless steel or other metal back cover.
— Gold. The case is made of jeweler's gold or has a gold-plated finish. Note that the colour of such a case can be different: in addition to the classic yellow, there are also white and red gold. Anyway, such watches are very expensive, and look accordingly; they are designed mainly for those who need not so much a device for determining the time as a rich fashion accessory.
— Silver. Although cases made of silver jewelry are much cheaper than gold ones, this material still belongs to the status ones, and is used not so much for practical reasons, but as a symbol of the high cost of watches and the wealth of their owner. However, for a number of reasons, silver has not received much popularity in watches.
— Wolfram. Tungsten alloys are not cheap, but they are very strong and reliable, and also look stylish. Another feature of this material is its very high melting point; from the practical point of view, this point is not significant, but it is important as a fashion detail, emphasizing the high reliability of tungsten. At the same time, for a number of reasons, such alloys are not widely used in watches.
— Bronze. Quite a rare and specific option, used similarly to copper — in order to give the watch a stylish look. The basis of bronze, in fact, is copper, and tin is most often added to this alloy, but other components can also be used. Accordingly, the colour of such material can be different — yellowish, reddish, brown.
