Watches with an enamelled gold overlay on the movement are exceptionally rare although not unknown. A watch with such a plaque, also with gold and enamel frames and rock crystal covers was sold at Christie's Geneva in 1989 . The movement was stamped with the initials MB, and certain of the translucent enamel colours indicated that it might be of French origin. Indeed without a signature it is difficult to be definitive as to the country of origin of the present lot. The technique of the enamelling is common to both French and German watches and jewels of the period, as indeed is the construction of the movement.
The style of ornament known as Cosse-de-Pois (pea-pod) flourished for only a short period during the first half of the 17th Century and mainly in France. Although a number of artists created and published designs, very few items of jewellery and even fewer watches were created using the style. Peter Fuhring and Michele Bimbenet, whose extensive work on the subject was published in 2002  recorded some forty engravings dating between 1612 and circa 1640. Amongst these can be noted Jacques Briot, Paris,1629, and Pierre DeLaBarre, Paris circa 1640. In addition there is the series of monogrammed prints stamped AD and dated 1608 , and the series by Jean Toutin, the famous designer, engraver and enameller published in Chateaudun in 1619.
A further set of designs were engraved by the Strasbourg artist Isaac Brun, after Peter Symony and published in 1621. Strasbourg was a free Imperial city in the the south west of the Holy Roman Empire, with a guild of exceptional gold and silversmiths.
