Copied details from my prior thread:
The Coating
- Optically clear with slight Blue/Purple hue
- Approx. 1% reflectance of visible light on the coated side
- Durability: This will be a DURABLE AR COATING. Let's put this in perspective: Our coating will meet military spec Mil-C-675 for durability. As such, it can be handled with bare hands and very easily cleaned, if required. However.... it WILL NOT withstand the "screwdriver test" as uncoated sapphire will. So... it is durable, but it can and will scratch if you're not careful!!!
- Single sided OR Double sided coating is available. There will be no price difference, but before deciding to go with a double side coating please refer to gen forums and RWG posts where people are actually removing the outer AR coating on their watches for various reasons!!!
How this will work
Please post your intent to commit here. If you have any uncertainty about honoring your commitment, then do not post. If/when we have enough of a commitment to begin a run (40 crystals is a nice sweet spot), then I will provide an address (my address) to everyone participating. I will provide shipping instructions and you will ship your crystals to me. I will not be removing crystals from watches for anyone. I will package the crystals, label them, and then send them to the coating house as a single lot. The coating house will return them to me, and I will then ship them back to their owners.
Payment: At this time I would like to avoid paypal. The easiest thing (for me) is probably going to be a bank check (either money order or cashier's check) that is mailed to me along with the crystals.
