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.
Interested in writing for the Horological Journal? Please read our contributor's guide.
Hello and wecome to the April edition of the Horological Journal.
This month sees the conclusion of our three-part series 'Completing Derek Pratt's H4', which has been written by Roger Stevenson FBHI and Carl Murray of Charles Frodsham & Company Limited, accompanied by some stunning photographs.
Also in this issue we see Guy Gibbon's series on 'Watching a Going Barrel Mainspring Develop' come to an end. It has been an informative and interesting series which has brough much reader interest. Look out for more from Guy in the near future.
We welcome a new writer, Antonio Gomez, who looks at the 'IWC Vintage Portuguese Ref. 325 and the Identification of its Hallmark', while Robert Horan MBHI, a HJ regular, describes the difficulities he encountered while servicing a Ladies' Tudor Mini Sub.
BHI Chief Examiner David Poole FBHI and British School of Watchmaking's Alan Burtoft FBHI, have put together a short instructional guide on The Etachron Balance Spring, which marks the re-commencement of work on the Professional Grade of the Distance Learning Course. Part 1 is included in April, with Part 2 to follow in May.
In addition there's all the regulars, letters, branch reports, news, After the DLC, book reviews and Bench View.
The 'Letters' pages provide a great opportunity for discussion and debate, whilst 'Branch Reports' provide updates of local activities, and regular 'Bench Views' illustrate life from the bench of a clockmaker and a watchmaker.
