Have a very nice original no 27 clasp and a 22mm red strap .Which i don't now what material it is -.It's a little velvet like . The clasp is 16 mm and the strap is 22mm . Was thinking of doing a new strap out of the red strap but that is not going to happen . Will sell it instead . $100 + shipping . The clasp are expensive if you find them ? More pictures let me now ?
