A high-quality guide plate for automobile timepieces needs to have the following characteristics in design and manufacture:

1. High-temperature resistance: The guide plate of automobile timepieces needs to be able to withstand the heat of the engine under high-temperature working environment, and has good high-temperature resistance and is not easy to deform or fail. High-quality chronograph guide plates are usually made of high-temperature resistant materials, such as aluminum alloy or stainless steel, to ensure stability and durability at high temperature.

2. Corrosion resistance: The guide plate of automobile timepieces needs to have good corrosion resistance, which can resist the corrosion of the guide plate by corrosive substances inside the engine and prolong its service life. High-quality timepieces guide plates usually adopt anti-corrosion treatment or special coating to improve their corrosion resistance.

3. Structural strength: The guide plate of automobile timepieces needs to have sufficient structural strength, which can withstand external forces such as engine vibration and road bumps, and is not easy to deform or break. High-quality chronograph guide plate usually adopts enhanced design or structural optimization to improve its structural strength and stability.

4. Diversion effect: The guide plate of automobile timepieces should have good diversion effect, which can guide air flow, reduce wind resistance and improve the driving stability and fuel economy of vehicles. High-quality chronograph guide plate is usually designed and optimized by fluid dynamics to ensure the best diversion effect.

5. Convenient installation: The guide plate of automobile timepieces needs to have a convenient installation method, which can be perfectly matched with the structure and other parts of the vehicle, and the installation process is simple and fast. High-quality guide plates for timepieces usually adopt standardized design and precise machining to ensure the accuracy and stability of installation.

To sum up, a high-quality guide plate for automobile timepieces needs to have the characteristics of high temperature resistance, corrosion resistance, good structural strength, diversion effect and convenient installation, so as to ensure the performance and safety of vehicles.
