The Sinclair Harding Workshop

Established in 1967, Sinclair Harding continues to honour the historical tradition of fine English clockmaking, embracing the horological industry’s ideals of precision, quality and perfection. The exquisite detail of the clocks, each one crafted to suit the individual requirements of each client, is testament to the trademark skill and dedication of Robert Bray FBH1 and his fellow craftsmen, with every delicate stage of production carried out in our Yorkshire based workshop.

Sinclair Harding Clock Making WorkshopWhile we continue to preserve original reproduction techniques, investment in latest technology has allowed us much greater flexibility for developing new, exciting ideas, while enabling us to maintain the highest level of accuracy and attention to detail that Sinclair Harding is renowned for. This mix of traditional skills and hi-tech processes ensures that we offer all our customers the very best service possible.


Any Sinclair Harding project begins with the customer and their bespoke requirements, however complex they may be.


We encourage our customers to get involved with their clock design at every stage of the process, making each project a unique and rewarding experience.

SolidWorks CAD DrawingsFollowing initial discussions with each customer, we produce highly detailed 3D screen models of all working parts and assemblies using SolidWorks technology. This enables us to give our customers a clear picture of their own exclusive desgin, viewable from any angle.


SolidWorks also gives us the flexibility to develop new design ideas and innovations and make running changes far more effeciently and effectively than ever before.

CNC Machining of Clock PartsFrom the 3D model, engineering drawings are produced so that CNC programmes can be generated via CAM software.


Wire erosion begins to produce the plates, taking 2-3 days.


Plates are milled, serial numbered, stamped and engraved. Bridges and springs are fitted to the clock plates.

Fusee chain manufacture at Sinclair HardingOur Fusee chain suppliers, Mavis and David decided to retire at Christmas 2013, with nobody coming forward to carry the business on, we agreed to buy their business and in January 2014 collected the first batch of machinery from David's workshop in Devon and moved it to Huddersfield. Over the following few months David and Mavis shared their knowledge acquired over many years and we have been painstakingly learning this almost lost art. This wonderful addition to Sinclair Harding must make us about the most complete clock making company to be found.

Clock FinishingEvery part is polished to a high degree of finish, mostly by hand, but with the help of a wide variety of tools. Each part, seen or unseen, is given the same amount of care and attention.

Clock CleaningAfter polishing, the parts are cleaned in an aqueous ultrasonic cleaning tank and meticulously inspected for any imperfections, which can still be corrected at this stage.


The final process prior to assembly, is the plating, either in Gold or Rhodium, of all the Brass parts.

Rhodium and precious metal plating services in the UKRhodium and Gold Plating services are available. More information coming soon. Please contact us on: 01924 840666 if you have any questions.

Clock AssemblyWe begin with the pinion assemblies and greasing of the mainsprings. Dials are engraved, silvered and finished in-house.


With every part polished and every screw, pin and spring in place, the final assembly begins. Every bore is given a careful last burnish and any tapped holes re-tapped and cleaned.

Testing the clocksThorough checks are made at every stage to ensure that on completion the clock will operate perfectly from the very first moment.


The most exciting part in the whole process for us is when the movement starts ticking for the very first time.

Clock Bases & Glass ShadesOur bases and protective glass shades are made in our workshop. The bases are usually made from marble or wood which has been french polished over a number of weeks. The movement is fitted to the base and the glass shade carefully placed in position to allow perfect visibility.

Clock cases for transportationWe even make the cases! Our clocks are shipped all over the world, so we have worked hard to develop a style of case that ensures our clocks arrive at their final destination in perfect working order.
