The spiral compensator (1) comprises a temperature compensated core (9a) formed from a non-metallic material (11a) and partially coated with a layer (7) that is stable to moisture to make the spiral compensator less sensitive to climate variations. The moisture stable layer has a thickness of less than 50 nm, and is electrically conductive, diamagnetic, paramagnetic or antiferromagnetic. |
