Clear vs Blue AR Coating
If your sapphire crystal offers AR coating choices, here is how the two types differ.
Clear AR
- Look: coating nearly invisible — dial colors appear exactly as designed
- Best for: purists who want true-to-design color reproduction
- Tell: only a faint hint of coating at extreme angles
Blue AR
- Look: visible blue tint on the crystal at angles — the "modern sports watch" signature
- Best for: adding visual pop; masking slight reflections with intentional color
- Tell: unmistakable blue flash under light
Which to Choose
| If You Want... | Choose |
|---|---|
| Vintage authenticity | Clear AR (or no AR — vintage crystals had none) |
| Modern flagship look | Blue AR |
| Purest dial colors | Clear AR |
| Extra visual interest | Blue AR |
Coating Placement Matters More
Underside-only AR cannot scratch off in daily wear; double-sided AR maximizes clarity but the outer layer can fine-scratch over years. Underside is the practical choice. See our crystal and AR guide.
Frequently Asked Questions
Can I add AR later?
Some specialists coat existing crystals; usually easier to buy pre-coated during your crystal upgrade (see the sapphire upgrade guide).
