There are two addresses for David Keys listed in London, namely one on the Strand around 1881 and one on Picadilly between 1863-1874. Listed as, ‘ Watch and chronometer maker to the Admiralty’ and interestingly, as a wholesaler. They would likely have supplied good-quality watch movements elsewhere.
