Grande & Petite Sonnerie striking: A clockwatch strikes at every passing quarter hour exactly in the same way as a clock. In the present watch, two options are available depending on what the user prefers: Grande Sonnerie, whereby the hours are struck followed by the quarters at every quarter-hour and Petite Sonnerie whereby the hours are struck at the hour and at the quarters only the quarters are struck. A silence mode can be activated when striking is not desired, for example during the night. The grande et petite sonnerie striking mechanism is one of the most complex single complications possible in a watch, it is thought that less than ten Patek Philippe clockwatches with no other complications were ever made. Two examples were produced for the legendary watch collector James Ward Packard: see: Huber & Banbery, Patek Philippe, 1994. P. 240-241. Clockwatches with no added complications are far less common than those with multiple other complications, to find an example by Patek Philippe is exceptional.
