126000-0006... purchased at MSRP... before the stupid Tiffany hype via 5711! funny thing is that when colored OP was initially announced I told friends these are rolex swatches. buy all the colors and wear one a day ... I don't like red or dark blue and hate anything green.... so that leaves pink, turquoise and yellow.. I took all three. then 6 months later they went to 2x msrp and now turquoise is mid 30's....
