If you have to deal with fragile organic glass, on which there are minor defects, then toothpaste is suitable for their elimination. Use here should be exclusively colorless paste, which does not contain granular components and does not have a whitening effect.

How to polish glass on a watch if there are minor scratches? To begin with, a small amount of toothpaste is applied to the prepared piece of cotton wool. You can also use a piece of thin cloth or a felt cloth that is designed to wipe the optics.

Glass is laid on a flat, solid surface. Light smooth movements in one direction, practically without pressure, polishes the product.

As soon as the defects disappear from the glass, the latter is cleaned from the traces of toothpaste with a clean, moistened cotton swab moistened with water. If polishing has not allowed to eliminate all scratches and scuffs, it is worth repeating the procedure several more times.

To polish a watch glass at home, made from a natural base, using toothpaste will be extremely problematic. To eliminate defects here you will have to use a grinding machine.

The work is performed in the following sequence:

  1. The glass is removed from the watch case and delicately wiped from dirt with a cotton swab moistened with an alcohol solution.
  2. A polishing wheel is mounted on the grinding machine. The latter is processed with a GOI paste of low grit, after which it is launched at low speeds.
  3. The glass is slightly pressed against the circle. Polishing is carried out in the direction from the edges of the product to its central part.
  4. As soon as the abrasions disappear from the glass, a small amount of mineral oil is applied to the cloth. Using circular motions in one direction, finishing polishing is performed, which makes it possible to achieve complete transparency of the product.
  5. Finally, the remaining mineral oil is removed with a cotton swab moistened with alcohol.

Sapphire polishing

How to polish a watch glass made of a sapphire base? One of the most effective solutions here is the use of GOI paste, designed for "rough" work. You can purchase a polishing agent in almost every hardware store.

As in the previous case, the glass is previously removed from the watch case. Coarse grained GOI paste is applied to a pre-moistened cotton swab. Next, the glass is polished in a circular motion for several minutes. At the end, the product is wiped with cloth dipped in alcohol.

If there are large scratches on the surface of the sapphire crystal, the procedure is carried out using a polishing wheel on a grinding machine. In order not to damage the product, it is necessary to maintain vigilance during the work, performing delicate surface treatment.

Some sapphire crystal watches contain anti-reflective coating. In this case, it is not recommended to resort to its independent processing. To eliminate defects in a similar situation, it is better to hand over the clock to the workshop.
