professional sapphire-crystal polishing
The watch crystal is one of the key elements of any timepiece. It safeguards the dial and movement from dust, moisture, and external damage, while in many luxury watches it also serves as a distinctive aesthetic feature.
Although sapphire crystal is remarkably durable, it is not entirely immune to damage. Over time, scratches, chips, or even cracks may appear. When the damage is severe, such as deep scratches or a fractured crystal — a full sapphire-crystal replacement becomes the only reliable solution.

Our service center is fully equipped with professional-grade tools and materials, ensuring that our master watchmakers deliver fast, precise, and impeccably executed service every time.
Sapphire crystal is a hallmark of high-end Swiss timepieces, signifying exceptional quality. As one of the hardest materials used in watchmaking, second only to diamond, sapphire offers superior resistance to scratches and everyday wear, far surpassing standard mineral glass.
While sapphire is significantly harder than mineral glass, it can still be polished using a specialized compound designed for crystals with internal anti-reflective coating, ensuring the AR layer remains intact. This method is ideal for eliminating light surface marks, though restoring deep scratches is considerably more complex.

key aspects of sapphire crystal polishing
A skilled watchmaker can restore both sapphire and mineral crystals that have been scratched or damaged through regular wear. Polishing is significantly more affordable than a full crystal replacement and saves you money, while preserving the original appearance and performance of your timepiece.
Sapphire crystal is exceptionally durable thanks to the unique properties of the material. Home polishing is not advised, since using the wrong abrasive can worsen the damage and create additional defects. Professional treatment is the safest and most effective solution.

Our master watchmakers follow a precise and proven procedure:
- They begin by identifying the exact composition and hardness of the original crystal, since this determines the appropriate tools and polishing compounds needed for safe restoration.
- They select the optimal polishing method based on the depth and nature of the damage, using professional restoration pastes with varying abrasiveness and, when necessary, specialized polishing equipment.
- They then process the crystal. To protect the case and movement, the crystal is carefully removed before polishing and reinstalled once the work is complete.
