Which Omega bracelet is this please?

[Jeremy67]

And is it correct for a Speedmaster 4.5?

I believe it is generally called the "Holzer" bracelet, marked as such on the clasp, and is made in Mexico (also marked as such). It is correct, but should only be found on 176.0012s from the American market, and is usually quite early in the run (which lasted ages, 1974 to 1985 or so).

Thanks, I like it, more interesting than the normal one (whose code escapes me).
