Conservation, education and practical research are at the heart of The Clockworks. We have a regular Conservator-in-Residence, who works both on the in-house collection and on private projects, and our fully equipped studio is a training ground for future electrical horology specialists and conservators.
Conservator-in-Residence

Alex Jeffrey is an industry-qualified conservation-led clockmaker who started working for a clockmaking company during term breaks whilst studying towards his bachelors in Engineering. Immediately drawn to horology for its technical aspects, considered approach, craft skills and the opportunity it gave for creative expression, Alex followed a traditional path to formal training: a structured, time served, five-year apprenticeship with Thwaites & Reed Clockmakers.
In 2021 he joined the in-house clock team at The Palace of Westminster, working on the nationally important collection of heritage clocks across the estate, and on the major restoration of the Great Clock of Westminster (affectionately known as Big Ben). He has worked independently and collaboratively on restoration projects across the UK and Switzerland and is the consultant horological conservator for the Goldsmiths Company. In March 2023, he left The Palace of Westminster to focus on his private practice, The Alex Jeffrey Clock Company Ltd (which he founded in 2019), and joined The Clockworks as Conservator-in-Residence. Here, he continues to work on heritage domestic clocks as well as public clocks, while also servicing and conserving The Clockworks’s collection.
Previous Conservators-in-Residence
Johan ten Hoeve trained as a furniture maker in Amsterdam. From 2007 until 2011 he studied at West Dean College focusing on making replicas of artefacts for exhibition. This included constructing a version of the year-going clock by Thomas Tompion for the Royal Observatory, Greenwich. Johan was Conservator-in-Residence at The Clockworks from 2012-23. He helped establish the museum layout, and gave regular tours to visitors, while also working on his own private clockmaking and restoration projects. He is now in the Netherlands taking over his family’s clockmaking business.

James Harris studied at Birmingham School of Jewellery, specialising in watches, and winning an award from the AHS for his masterpiece clock project. He has worked for Tag Heuer, Omega, and Christopher Ward (among others), and returned to Birmingham as a lecturer. In 2017 James was offered the opportunity to fill the space left by the outgoing Tabea and jumped at the chance; he used his time at The Clockworks to start his own private practice. Harris Horology is now based nearby in Camberwell specialising in repair of vintage watches and antique clocks.
