Yeah it's from the camera filters.
I love that strap on your beautiful 3717 and my affordable grail the moon watch! I can't wait till I get my 3717 from vac
Also now a dealer here too

I had a PAM with his CG and it's very nice. Had to mod the feet and CG lever to get it to fit the T crown but it snapped nicely!
haha It was a leap of faith. The watch has survived showering (steam is notorious for finding flaws in your watch) so I had good feelings about the pool. Definately my point and shoot's strap was wrapped around my wrist!
