Hello Fritz,

The dial screws are 2.00mm dia. X 0.45 pitch x 5mm long.

Paul.

Thanks Paul. As we should all know, Chronometrics, like their Jaeger predecessors, are entirely metric. Too many people fix them to their brackets with 1/4" BSF or 2 BA nuts instead of the correct 6mm ones. You can horrify the rivet counters by attaching your instruments with freely available stainless nyloc 6mm nuts. Stops them falling off...
