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.
