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 all Monster models, plus Seiko Baby Turtle watches). The crystal is 4.25mm thick and 30mm in diameter.

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.

    The DD crystal sold by Long Island really improved the appearance of my Seiko Monster SRP 315. It provides durability and adds clarity to the dial. My watchmaker, who replaced the crystal, remarked that the crystal was of high quality and was easy to install.
