The Sherpa Graph Mark Ia is currently worn on a Hirsch Capitano strap with RHD deployant clasp.
The set-up was originally purchased for a SARB017, but I ended up putting the Alpinist on a Strapcode Jubilee bracelet and the Capitano went into a drawer for quite some time.
The early Sherpa Graph is a recent acquisition.
I had the "Ia" on a dark gray rally strap at first, then on an Uncle Seiko BoR bracelet, but I like the thin-padded alligator strap the best so far. 😉
