Extended data:
Watch style:
1. Brass: Copper is soft, easy to form and low in cost. The copper shell must be electroplated after processing: palladium nickel (pnp), ruthenium, gold, etc. , so as not to damage the coating, exposure, and avoid contact with acid, alkali and salts.
2. Stainless steel: wear-resistant, rust-proof, antimagnetic and corrosion-resistant. Do not touch a certain concentration of acidic/alkaline liquid (such as sweat) for a long time, and materials with similar or higher hardness are easy to be scratched.
3. Ceramics: It has unique luster, high hardness, corrosion resistance, high temperature resistance and no damage to the skin, but it is fragile and brittle, and the edges and corners should not be too sharp. Stainless steel lining must be added to connect the back cover and other accessories.
4. Tungsten steel: cemented carbide (tungsten titanium alloy) has high hardness, good wear resistance and toughness, heat resistance and corrosion resistance, but the impact resistance is slightly poor, so collision and falling should be avoided.
5, pure gold: soft texture, low hardness, not wear-resistant, generally choose K gold, the price is higher, but it has the function of preserving value, which is the first choice for watch collectors. Avoid contact with mercury (mercury), otherwise it will turn black and lose its luster.
6. Leather: calf leather, sheepskin, ostrich skin, crocodile skin, lizard skin, pearl fish skin, etc. OTO watches mostly use leather straps, which are soft and comfortable to wear and can better reflect the noble and elegant temperament of the wearer.
