Chronometric speedo fix

Forums

The Smiths chrono speedo on my 1950 ES2 has a nice patina, but the trip and odometer have stopped working. The speedo itself is fine. Is it possible or advisable for me to get inside and fix this? I don't really want a full restoration or exchange unit. What d'you reckon?

Repairing chronometrics is not difficult,and theres plenty of info on the net.Listed under Jaeger[who licenced Smiths to make them].You will need some clockmaker type tools,small screwdrivers ,probes,punches etc.In the old days if the bezel was tight,youd cut a couple of slots in,but now its best to remove with a large worm drive hose clamp.Of course then if something broke,another speedo cost 5/-.
