Formerly in the Bloch Pimentel collection, and sold in the sale of same in May 1961 by Me. Ader, Paris. Liternture: Illustrated and described in Tardy, La Pendule Française, Paris 1981, Vol.I, p.71. Two watchmakers of this name appear to have been working at the same period. Records indicate a Jehan Greban, who worked initially without a master's mark before becoming Maître; possibly the Jean Greban recorded as being taken as apprentice by Jehan Bourillon on 15 January 1548. In the Enclos du Palais in 1549, subsequently in Rue St-Germain-des-Prés, 'Au Nom de Jésus'. Killed in the massacre of St.Barthélemy in 1572. However, Tardy also notes a maker of this name as being cited in 1574. The apparent interpretation of the Roman numerals engraved on the band of the case gives a date of 1463, which has no immediately recognisable relevance to the clock. It therefore seems likely that the engraver simply macle ail error in calculating the correct letters; by no means an unheard of occurence, as many craftsmen were virtually illiterate. A totally appropriate date, on the other hand would be 1563 - a hundred years later.
