The present watch represents the state of the art in watch manufacturing from the heydays of complicated and ultra complicated timepieces. Uniting two main complications established at that time, the split second chronograph for timing purposes and the distinct minute repeating for the acoustic pleasure, it is furthermore enhanced by the superior quality case with hidden hinges, the highly jewelled movement and its excellent overall condition.
Patek Philippe launched the production of minute repeating split seconds chronograph in the late 1870s. The combination of these two complications became one of the firm’s specialities, a large number of the production was sold to the North American market.
Patek Philippe's 1902 Patent for a split seconds chronograph feature is published in Patek Philippe Pocket Watches by Martin Huber & Alan Banbery, first edition, page 58, fig. 51.
