Born in 1608, Estienne was the eldest son from his father's first marriage to Catherine Lescuyer, and as such gained his right to mastership through patrimony - Fils de Maître. - in 1656. That he received the patent so late in his career is certainly due to his having worked with his father up to the time of the latter's death circa 1654. He married Elisabeth Ronnieu, by whorn he had three sons who all subsequently became watchmakers. Estienne died in 1676.. Literature: Illustrated Clutton & Daniels, Watches, figs. 92 A - C. Cammerer Cuss, Watches, plate 23. Exhibited: Antiquarian Horological Society 10th Anniversary Exhibition, Science Museum, May - August 1964, exhibit No. 63. The cases of both this watch and the previous lot are particularly well engraved with very similar designs incorporating summer flowers composed in an open and flowing manner. They seem to be taken from one of the anonymous XVIIth century designs for watchmakers, reproduced by E. Gelis : L'Horlogerie Ancienne, Paris 1949, pl. 13.
