Correct, that was me.
The front side fits 95% I'd say. The back side a little less because the case shape of the Speedy is different from the Rolex. I originally bought this red RubberB strap to fit my platinum Yachtmaster that had a red second hand.
Here's a picture of the Speedy back side so you get a better feeling of how it looks.
