Description: Owing to the rapidly developing railway and electric telegraph systems in 19th century Britain, the need for an accurate and comprehensive distribution of Greenwich Mean Time (GMT) for the nation became a priority for the Royal Observatory in Greenwich. Many inventors worked to develop timekeeping instruments. This pocket watch has two minute hands.
