Jean-Joseph de Saint-Germain produced a number of ormolu clock-cases of this form with small differences, and the present example is attributed to him based on the other signed examples. This includes a clock in the Metropolitan Museum of Art (F.J.B. Watson, The Wrightsman Collection, New York, 1966, vol. II, cat. no. 183), another from the collection of Otto Kahn, sold Christie's, Monaco, 20 June 1994, lot 112, and a further example sold first from the Alexander Collection, Christie's New York, 30 April 1999, lot 155, and subsequently sold from Le Pavillon Chougny, Christie's, London, 9 December 2004, lot 385. A further example signed by Gille l'Ainé sold Christie's London, 7 June 2005, lot 329
