Double-Dome AR Sapphire Crystal to Mod Seiko Monster Watches #Monst-DD This is an after-market double-dome sapphire crystal that you can use to mod your Seiko Monster watches (fits Monster Gen 1 and 2 models, plus Seiko Baby Turtle watches). The crystal is 4.25mm thick and 30mm in diameter. Note: It has blue anti-reflective coating (on the bottom of the crystal only) which imparts a blue hue at some angles. Also, It is a double dome. Domed top, domed bottom, so it does not have a magnification effect.
