The Horological Journal

The Horological Journal

The Institute is proud of its Horological Journal, which is the oldest technical journal in the world and has been published without a break since September 1858.

A copy of HJ is sent to every member each month, and contains a wealth of news and information of interest to horology enthusiasts.

We try to maintain a good balance of articles in each issue, covering clocks, watches, turret clocks and electric timepieces in articles that may be theoretical, practical or both.

Hello and wecome to the March edition of the Horological Journal.

We are delighted this month to publish a very special article about the making of tiny diamond escapement pallets, as part of the 'Completing Derek Pratt's H4' series. Carol Murray from Frodsham's has worked tirelessly to produce these revolutionary components, using equipment inherited from Derek that would not have been out of place in an eighteenth-century workshop. We feature on the cover of this month's magazine an exclusive view of one of those pallets and you can read more in our Article of the Month.

Also in this edition, we announce the second 'Harrison Decoded - Towards a Perfect Pendulum Clock' - a conference which will take place at the National Maritime Museum at Greenwich on Saturday 18 April. Don't forget to pre-book your tickets early as it's bound to be a sell-out.

Our construction series 'Making a Regulator to a New Design' carries on apace in this edition, with author John Reynolds FBHI looking at the Mounting Plate, Movement Plates and Pillars. This series, which was commissioned at the request of our readers, is expected to run until the end of the year.

Martin Foster FBHI, our Fairs Correspondent, reviews SIHH Geneva Salon, which showcases some exquisite complications from the finest Swiss watch houses; Lange & Sohn, Audemars Piguet, Greubel Forsey, Jaeger-Le-Coultre, Panerai and IWC all feature.

Tony Proctor looks at royal connections in his article 'A Watch by Henry Fish'; Derek Hughes proudly presents his 'Electro-Mechanical Fibre Optic Clock' which he spent 50 years thinking about and ten years making; and Guy Gibbons MBHI presents Part 3 of his 'Watching a Going Barrel Mainspring Develop'.

In addition there's all the regulars, letters, branch reports, news, After the DLC, book reviews and Bench View.
