......i did go for just one Comex....the 666 matt in the picture. I have never owned another....or been tempted even. I am such a big fan of the 1665 and 16660 references. But with this matt 666, with just 100 produced and only some 30 or so having ever surfaced for service at Rolex, there is something special for sure. Its been a long time since i had this one on my wrist
