Lum-Tec Phantom Sapphire Glass Crystal Upgrade for the M-Series
The Phantom Sapphire Crystal is effective for "blacking out" the face of the watch, yet still traps enough light inside to keep the glow burning at night! Amazing effect! The AR coating outside lets light in, and the mirrored inside traps in into the MDV lume. If added to your cart with your M-series watch, this custom sapphire crystal will be added to your watch by default.
- Custom made "phantom" sapphire crystal coating for all LUM-TEC M-Series watches
- The top side has a tinted, anti-reflective coating
- The underside has a mirrored back which will trap light underneath the crystal so that the luminescent markings will glow brightly
- Please Note: Adding this item to your cart along with a M-Series model will automatically upgrade the crystal on your watch. Adding this upgrade to your order may delay the order up to 3 business days. Customized pieces are NOT returnable for a refund, credit, or exchange.
