Glad you like the black straps with green stitches on my Milgauss. Interesting to note, I fixed these straps in my watch as soon as I arrived home from the Rolex AD so I never, absolutely never worn this watch with its original Oyster bracelet which is pristine since then. Guess some day I will need to try it with its original bracelet.
Regarding the orange and red straps on my Cartiers: I love these watches but wear them very little. Now with these straps I´m more often tempted to wear them. I feel they give a new "breath of life" to these watches with these OEM straps I specially ordered for them at the Boutique.
Cheers, Abel
