Tried in a buddy's Speedy Reduced today, just for grins. Nope. Too small on my ham hock 7 3/4" wrists. Plus I've gotten used to my co-axial Speedmaster so the difference was shocking. Likewise, my 44.25mm model completely eclipsed her dainty wrist. Strapped my co-axial back on my wrist and there it shall stay.
