Black Black Ceramic Deployment Clasp?

I'm about to take the plunge and buy the Seamaster Black Black Ceramic but I have small wrists (6") and the strap is too loose on the last setting. I know they make a shorter version of the rubber strap but it's for a 20mm lug and the Black Black is 21mm. So I'm looking for either a smaller 21mm rubber Omega strap that would fit my wrist size or.... I would rather have an Omega deployment clasp that fits on a 21mm Omega strap as the extra strap goes inside the band and takes up a little more room to make the wrist cozy.

Is there such strap or deployment clasp that would work with this timepiece?

My bad! I've been reading it wrong the whole time!


Do you have a link to this? They have the 21mm lug with a shorter strap?

Will a DSOtM strap set work?
