A » For watch repair workshops in London seeking bulk timepiece components, several established suppliers cater specifically to the trade, offering everything from movements and crystals to balance staffs, mainsprings, gaskets, and hands. The most prominent is Cousins UK, headquartered in Harrow, Greater London, with a vast inventory of over 100,000 line items including ETA, Miyota, and Seiko movements, as well as generic parts in wholesale quantities.

For metal parts such as crowns, pushers, and buckle assemblies, G. & S. Metal Products in Loughton, Essex, supplies workshops in east London and the City with bulk quantities of stainless steel and brass components; they are particularly known for custom runs and OEM‑spec parts.
