Anniversary Clock Identification: Black & White Edition

Collectors and dealers of these clocks know how vital it is to identify the movement fitted to an Anniversary clock, whether to classify, date or value it. Restorers and repairers need to identify the movement to select the correct parts. With an incorrect suspension wire, a torsion clock will probably run but will not keep the right time.

Mervyn Passmore has devised a unique way to identify the manufacturer and model of these clock movements quickly and accurately using a combination of maker's names, logos and the back plate width and height.

The information covers the majority of mass-produced mechanical movements manufactured during the last 100 years.

In 1976 Mervyn Passmore co-founded one of the world's leading distributors of clockmakers' supplies, and the records he kept and the experience and knowledge he gained over the years, combined with data and photos obtained from a large private collection of Anniversary Clocks, is now available to all.
