These units are assembled in individual jigs. The width and thickness of the spring may not be the same as for the spring which it replaces, but its torsion characteristics are nevertheless correct.
Due to the wide variations in characteristics of spring steel and because many older suspensions were made of bronze, it is impossible to supply a replacement wire simply by measuring the old one. Only a laboratory can establish the spring characteristics of the material. It is most important that the correct wire be fitted if a lot of wasted time is to be avoided.
To establish the correct replacement, you should refer to one of the specialist books on the subject, such as 'Anniversary Clock Identification' by Mervyn Passmore (0412 021226) or the 'Horolovar 400 Day Repair Guide' (our part number 0412 000126). www.anniversaryclockidentification.com has a free online 400 day movement identification system.
Alternatively you can send us an actual size scale drawing or photocopy of the blackplate of clock movement, showing all holes, screws and any text marked, for us to do this on your behalf. From this we can establish which factory made the movement. The name on the dial is often irrelevant. Please indicate whether a complete unit or just the wire is required. When only the wire is available, you may need to purchase a pack of blocks and forks. The kind of drawing we need to identify the model is shown. Please do not email it, because we cannot be certain that it will print out the same size. We have to compare your drawing with hundreds of similar actual drawings. Likewise, photos are no use for this purpose.
