Ahasuerus Fromanteel 

Early and important sun and moon watch by Ahasuerus Fromanteel II, circa 1690, SN 834. Fromanteel SN 842 is in the Ashmolean Museum

The Fromanteel family introduced pendulum clocks to England in 1658 and made exceptional clocks and watches from workshops located in both England and the Netherlands for two generations. Brothers John, Ahasuerus II, and Abraham, and their father, Ahasuerus senior, were well traveled and made watches and clocks for the English and Dutch markets from locations in both countries. This watch was made for the London market likely by Ahasuerus II who was running the business from The Hague and Amsterdam. It could have been retailed by younger brother Abraham who was located in London at this time.

The movement is gilt-brass with a four wheel verge and fusee movement that is signed Fromanteel London in outward facing script. Intricate foliate balance table and foot that is not bordered. Four divided tulip pillars and divided decorative fusee stop-work foot.  Silver regulator dial. No serial number on the movement but number 834 stamped on the outside of the box (inner case) as often found on early English watches of this period. This movement design with the fusee winding arbor at the neck of the balance cock and foot, and the foot attached with two screws is distinctive to very early Fromanteel watches.
