CHRONOMETRIC SPEEDOS
MAGNETIC SPEEDOS
VEGLIA REPLICA SPEEDOS
Smith’s speedos are rare. New ones are not available and used ones have often been repaired to death by hamfisted “mechanics”. Sometimes we can be of help with a lovingly restored clock. Please inquire with the original Smith’s number, as they are all different! Magnetic speedos only. from € 200,--

BrItish bikes till about 1963 use mechanical Smith’s chronometric instruments. Lovely clocks with a chrome plated screwed bezel and a typical white needle that follows a jerky path along the dial. Many chronometrics have suffered a violent and premature end at the hands of mechanics with penetrating oil, Birmingham screwdrivers and even soldering lamps who tried to fix the needles behaviour.
The successor was the magnetic with a rolled on chrome bezel. A simpler concept, but also quite vulnerable.
Around 1975 french Veglia clocks are introduced.
Most speedos use a square/square inner cable.
Tachos/rev counters are driven by a spade/flat end. Long nut on clock end is for magnetic speedos (often a groove has been made in the knurled nut).
Short nut on clock end is for chronometrics.
Veglia speedos use their own cables with a different thread.
