I replaced another domed sapphire crystal which had a bevel. This crystal transititions smoothly to my ceramic bezel insert and aligns beautifully. The slight blue A/R is subtle when it catches the light just right. I love the look it gives the watch.

NMK301 - SKX/SRPD Double Domed Sapphire Crystal (Blue AR)

Crystal is flawless. I had some difficulty inserting it and making sure it was even and balanced. But in the end, it looks perfect. The blue AR reflects beautifully in the daylight.
