I recently acquired the below pictured pocket. Very cool addition to my collection. I am looking for a bit more info on history. I know of John Dwerrihouse of London who was making watches in the 18th to early 19th century. This appears to predate his birth. The watch is signed; Dwerrihouse, Berkeley Park, 1672.
The case is gold and silver, with enamel monogram on back. It has a diamond endstone. The pierced work is wonderful. I am unable to locate any info in my library or online regarding an ancestor of John Dwerrihouse who was an English watchmaker.
Any assitance would be greatly appreciated.
