Sub Contract Engineering

Robert (Bob) Bray had one simple goal for Sinclair Harding, this was to be totally independent and capable of making every part for each clock. This has enabled Sinclair Harding to develop their in-house capacities to include precious metal plating, Fusee chain making, manufacturing and hand tuning bells, French polishing, engraving and hand silvering of dials, Bluing of screws and hands, even mainspring manufacture is now undertaken.  

Our skilled craftsmen coupled together with modern technology have enabled us to offer sub-contract engineering to the highest standard. We are able to work with one offs and batch quantities from design, manufacture to the end product using various materials and finishes.
