This is what you've all been waiting for -- 1:1 genuine Corundrum sapphire crystals for 44mm Luminor projects!
Below you will find the differences between OEM & C3 crystals versus DSN & Eddie Lee crystals, and why these C3 crystals are better than any other previously available crystals. All light source photos were taken in Barton Baker's laboratory.
First, here are the crystals used in this tutorial:
- Eddie Lee crystal (installed in mattusss' PAM009)
- DSN crystal (installed in BIGCROWN's Power Reserve)
- OEM PAM000K crystal (installed in BIGCROWN's 201/A project watch)
- C3 pre-V version crystal with no AR coating (installed in BIGCROWN's destro watch)
- C3 contemporary crystal with AR coating (installed in BIGCROWN's 111 project watch)
When a light source is directed at a crystal made with genuine Corundrum, such as an OEM Panerai crystal & the C3 crystal, the light entrance, exit, and refraction points are the same size. Also, there is no light distortion throughout the crystal. This is because genuine Corundrum is 99.99999% clear with almost absolutely no fissures, cracks, or impurities.
However, crystals made with anything other than genuine Corundrum, such as Eddie Lee, DSN, and Asian-made crystals, have deposits of impurities and have small cracks and fissures. Thus, when the light is refracted throughout the crystal, the light source is seen throughout the crystal, all impurities and fissures are visible, and becomes cloudier and cloudier the more times light is refracted.
This means that if you have a non-genuine Corundrum crystal installed in your watch, when you examine your watch up-close and from even further away, your dial isn't as clear as it could be if you have a crystal made from genuine Corundrum.
The diagram below shows the differences between genuine Corundrum crystal light refraction and crystals made from other material light refraction.
And here are pictures to show the proof of light refracting properties.
Eddie Lee crystal light refraction:
See how the light refraction resembles a staircase or a solid continuous zig-zag line?
DSN crystal light refraction:
See how the light refraction resembles a staircase or a solid continuous zig-zag line?
OEM PAM000K crystal light refraction:
See how there is no light seen passing through the crystal? The only light seen is at the top of the crystal and on the dial which refracts the light.
C3 pre-V with no AR coating crystal light refraction:
See how there is no light seen passing through the crystal, just like the OEM crystal? The only light seen is at the top of the crystal and on the dial which refracts the light.
C3 contemporary with AR coating crystal light refraction:
See how there is no light seen passing through the crystal, just like the OEM crystal? In fact, the only light seen is at the top of the crystal and on the dial which refracts the light, and because of the AR coating, the light entrances and refracting points are MUCH smaller than the even the light refracting points on the crystal without AR coating!
