See how single-sided and double-sided anti-reflective coatings typically change over years of wear and cleaning.
Double AR often looks darker and more “invisible” when new. As coatings age, cosmetic wear, marks or haze can become more noticeable depending on side, quality and cleaning habits.
If glare control is still acceptable but cosmetics bother you, some owners replace the crystal. Decide based on visibility impact, cost and whether the rest of the watch justifies it.
Does AR coating wear off? It can show wear marks, haze or reduced cosmetic uniformity over years depending on quality and abrasion.
Is double AR less durable than single AR? Double AR can look more impressive when new, but more coated surfaces mean more places for cosmetic wear to appear over time.
Why does my crystal look smoky or marked? Aged AR, cleaning abrasion and micro-wear are common causes of cosmetic change.
Can AR coating be polished back? Usually the practical options are live with the wear or replace the crystal, depending on severity and setup.
