I have a both Ur Speedbird and SpeedbirdII, love 'em both but for different reasons.
SBII improved on the original by moving the minute chapter outwards, spoiled by having text on the dial though. It's the very lack of text that gets the questions asked and, to me, is a mark of confidence in the product. No name required.
SB3 looks good, no text is good for me, as would be 40mm. If you want a smaller one, buy an SBII! One thing though, having owned and sold a Yao Quad 10, personally I think silver/rhodium plated hands look cheap, and you've got to get the dial/crystal/case diameters in the same ratio as SBII or it'll just look fat, like the Quad 10 did to me.
