Release Date：2023-07-11 11:22
For watch enthusiasts who wear their timepieces every day, it is almost inevitable that even with the utmost care, watches can suffer minor scratches from sharp objects. While light scratches can be repaired using basic polishing and sanding techniques, deeper scratches require a more meticulous repair process. This article will delve into the two primary surface finishes of watch cases: polishing and sandblasting, or a combination of both. We will explore the specific steps and techniques involved in repairing deep scratches on watch cases and bands, emphasizing the importance of adhering to the original craftsmanship.
Repairing Localized Deep Scratches:
To address deep scratches on specific areas of the watch case or band, the initial focus should be on using a whetstone for polishing. This process requires close examination under magnification to ensure an even removal of scratches. Once the majority of the scratches have been smoothed out, select sandpaper with an appropriate grit and carefully sand along the original sandblasted pattern. Typically, the sandblasted pattern radiates from the center of the dial. Patience and precision are key during this meticulous process to achieve a realistic and visually pleasing outcome.
Tools and Techniques:
The choice of tools is crucial when utilizing sandpaper. It is recommended to use hemostatic forceps commonly used in surgical procedures. Take a small piece of sandpaper, fold it, and secure it tightly with the forceps. Follow the original pattern lines parallelly while sanding. Sapphire glass, being highly durable, can be disregarded during the process. However, when working with stainless steel watch cases, extra caution is necessary to avoid accidentally scratching the surface. If needed, cover the glass with adhesive tape for added protection.
Maintaining consistency in the sandblasted pattern is essential. All sanding strokes should align with the original pattern, radiating from the center of the dial in a radial manner. This method can be applied to remove scratches and rejuvenate the appearance of both watch cases and bands. Straight-line patterns are relatively easier to work with, but for watches with concentric circular patterns, electric-powered tools may be required.
Repairing Cases and Bands with Combined Finishes:
For watch cases and bands featuring a combination of sandblasting and polishing finishes, the repair process involves sanding first and then polishing. However, it is necessary to cover the already repaired sandblasted areas. Simple adhesive tape can be used for this purpose, while more professional approaches may involve the use of metal templates during the polishing phase for precise coverage.
By following the proper techniques outlined in this article, you can effectively repair scratches on watch surfaces using sandpaper. Whether you're working with a sandblasted or polished finish, adhering to the original craftsmanship is crucial for achieving seamless results. Repairing localized deep scratches requires careful polishing with a whetstone, followed by sanding along the original pattern using appropriate grit sandpaper. Maintaining consistency and precision throughout the process ensures a professional and aesthetically pleasing outcome. Remember to exercise caution when working with stainless steel watch cases to prevent unintentional damage. By applying these expert techniques, you can restore the beauty of your timepiece and enhance its overall appearance.
