–
An important astronomical verge pocket watch of museum quality, circa 1670.

Silver inner case, gilt dial, engraved foliate scrolls. Full plate movement, chain/fusee, two-arm steel balance.

Johannes Jaques of Rotterdam was active in the second half of the 17th century.  This verge pocket watch is in marvellous condition, the exquisite floral ornamentation of the dial continues into the movement to the verge holder. The symbols for the weekdays are described in Old Dutch and as finely engraved as the expressive faces of the moon phases. The silver balance cock also has an unusual shape. Alltogether this is a striking piece of technical and artistic excellence.
