Anyone wishing to learn more about pocket watches, therefore, whether as a collector or through a general interest in the subject, should find this authoritative title useful. Covering the period of 1850-1940, the authors cover in depth every type of pocket watch produced, explaining in clear, uncomplicated language precisely what to look out for and, of equal importance, what to avoid. Unlike so many other books on horology, they do not concern themselves with largely unobtainable or outrageously expensive museum examples but prefer to concentrate their attention on affordable watches which their readers are actually likely to come across in everyday situations. Illustrated throughout with hundreds of previously unpublished photographs, the authors provide not just portraits of watches but also numerous examples of their internal workings or movements. Nothing escapes their attention, from alarm to late verge, and the instruction and advice should commend itself to prospective purchasers and cataloguers everywhere.
