Queen Victoria and Prince Albert bought many watches from 1845 onwards, often as personal and state gifts. At the Great Exhibition of 1851 Aubert & Klaftenberger exhibited many clocks and watches and were granted an Honourable Mention from the Jury. In 1859 they were granted an official Royal Warrant.
