Juko, same bracelet was used by Heuer for later Monacos and early Silverstones, bracelet has expandable clasp and is signed with the Heuer logo. Obviously endpieces were different as pinholes are more integrated in the case at Silverstones.
You will find the strap for reference in my book at page 234 and page 238. Both Silverstones are nos and came originally with this kind of strap. On page 204 you will find a 1133 B Monaco using the same strap with the Monaco endpieces.

: i am interested in the bracelet Clay Regazzoni is wearing on his
: blue Silverstone, this is a picture from the 1974 catalog,
: borrowed from the catalog section (thanks Jeff!). This bracelet
: is different from the normal bracelet, the inner links are
: smaller. It looks like a Monaco bracelet. Does anyone of you
: know if there was a second type bracelet on earlier versions? Or
: is Regazzoni wearing a Monaco bracelet on his Silverstone?
: Any input is welcome!
