Many years ago, I purposefully bought a speedy fake in some far flung Asian market (Bangkok I think) purely to see if I liked the general look and size on my wrist. I never had the cheek to ever wear the watch in public again and it languished in the bottom of a drawer.

Just having a sort out and thought you might be interested in a side by side. The two buttons move the day date wheels. It's an auto movement, with winder and hacking. The bracelet is a bit cheap and nasty but the watch weighs almost the same as a speedy (130 vs 150g). Cost less than £30 from memory.
