When light scratches are only cosmetic, and when they need professional polishing or replacement.
Fine hairlines that do not block the time are often cosmetic. Dense haze over the markers, or deep chips that catch light and hurt reading, point toward professional polish or crystal replacement.
• Acrylic is the most polish-friendly.
• Mineral sits in the middle.
• Sapphire resists scratches well, but deeper damage is often a replace decision.
• Readability matters more than perfect top-light photos.
Aggressive DIY polishing can worsen coatings or distort acrylic. Professional work is safer for valuable watches.
