"With the authorisation of César de Trey who had already registered the brand name Reverso, and Jacques-David LeCoultre, administrator of Patek Philippe at the time, eight of these Wenger cases including four in white gold and four in yellow and white gold were delivered to Patek Philippe between December 1931 and April 1932. The cases were fitted with different dial styles and layouts, the circular movements based on ébauches by LeCoultre, and eight Patek Philippe Reverso wristwatches, including one lady's watch, were sold under reference 106. The model did not meet the commercial expectations and production never went beyond these eight examples. Until to date, only the following five examples have appeared in public:
-white and yellow gold case no. 609'483, the present watch
-white and yellow gold cases nos. 609'429 and 609'482 as well as the lady's model in white gold case no. 609'431, all in Patek Philippe's prestigious Museum in Geneva
-white gold case no. 609'481, property of an important private collector
The remaining three watches fitted with white gold cases nos. 609'430 and 609'480 and white and yellow gold case no. 609'472 have never appeared in public."
