Metal is more reliable than plastic

When choosing a smartwatch, pay attention to what the body of the device is made from. Usually it is either plastic or metal. Plastic at least light and cheap, and not too resistant to damage. The exception is polycarbonate – a very durable plastic. Compared to a strong, but inexpensive material – stainless steel. Aluminum – is cheaper and lighter than stainless steel, but less durable and durable material, and scratches are even more afraid.

Display

The glass with which the front panel of the clock is framed is also different, and it is important to choose the one that best fits your lifestyle. Cheaper plastic glass, which is broken and easily scratched. Mineral glass is often found in smart watches. It is resistant to scratches, but it is inferior in strength to the previous version, although it is much more expensive.

The watch strap is made of different materials, just like the usual one. These materials have quite different properties, and therefore they should be chosen according to their taste. For example, silicone resembles plastic in properties, but soft and pleasant to the touch. In addition, it is relatively inexpensive. The rubber strap fits your wrist well, has a wide range of colors, cheap. Leather is very comfortable material, but expensive. There are certainly leatherette, worn they are worse and have other properties, but cheaper. Metal, in turn, is spectacular, durable and resistant to external influences. In the case of an allergy to one or another raw material, it is better to clarify the hypoallergenic composition of the bracelet and from this to repulse when choosing.
