This lens is highly transparent with rounded and smooth edges, ensuring a comfortable feel and preventing scratches during handling. Its sapphire crystal composition provides excellent transparency, a smooth surface, high temperature resistance, scratch resistance, and wear resistance, making it clearer and more aesthetically pleasing than standard flat glass.

Unlike ordinary optical glass which may have a green light transmitting layer, this sapphire glass features a white interlayer light transmitting layer.

Configuració i instal·lació

Accurate measurement is crucial for proper installation. Before purchasing or attempting to install, it is essential to measure the existing watch glass lens from your watch.

Measuring Your Watch Lens:

1. Remove the existing watch glass lens: Carefully remove the broken or old watch lens from your watch.
2. Use a caliper for accurate measurement: Lay the glass lens flat and use a vernier caliper to measure its diameter.
3. Measure edge thickness: Use the caliper to accurately measure the edge thickness of the lens.

Avís important: The lens diameter tolerance is ±0.05mm. Always use a caliper for precise measurements. Avoid using low-precision tools such as soft rulers, standard rulers, or measuring software, as these can lead to inaccurate readings and improper fit. The marked size of the lens does not include the waterproof ring, which typically adds 0.5mm to the diameter.

Once the correct size is confirmed, the new sapphire crystal lens can be installed. The installation process is generally straightforward for watch repair professionals or individuals with appropriate tools and experience.

Característiques operatives

Once installed, the single dome sapphire crystal lens functions as the protective cover for your watch face. Its primary characteristics include:

Manteniment

Maintaining the clarity and longevity of your sapphire crystal watch lens is simple:

• Neteja: After prolonged use, the lens can be easily cleaned by wiping it with a soft cloth.
• Avoid Harsh Materials: Do not use paper or overly hard cloths for cleaning, as these can potentially scratch the surface of the glass and affect its appearance.

Resolució de problemes

The most common issue encountered with watch lens replacement is an incorrect fit. Adhering to precise measurement guidelines can prevent most problems.

Problemes comuns i solucions:

• Lens Does Not Fit:

  If the glass lens diameter error is as little as 0.1mm, it cannot be properly installed. This is why accurate measurement with a caliper is critical. Re-measure your watch's required lens dimensions carefully before attempting another installation or purchasing a different size.
• Scratches on Lens:

  While sapphire crystal is highly scratch-resistant, it is not entirely scratch-proof. Avoid contact with extremely hard materials like diamonds. For cleaning, always use a soft cloth to prevent surface damage.
