The Vintage Wrist Watch Company has dated this piece to the 18th Century.
John Dwerrihouse was active from 1770 until his death in 1805 (according to the British Museum).

The watch has a signed movement with a pierced balance cock with diamond end stone, and a silvered regulator disc. The movement was originally a verge but was subsequently converted to a lever mechanism in about 1820 for greater accuracy. It is working well and keeping good time.

The watch measures 48mm diameter excluding the stem and the loop. The case has age related surface marking but overall very nice condition. The original domed lens has short scratches across it but not too detrimental. The domed enamel dial is in good condition and has just a couple of hairline cracks, a faint one running between 9 and the centre, and another slightly more visible one starting next to number 6 and running upwards. The gold hands are the correct style for the age of the watch so could well be the originals.

The watch sits nicely within the underpainted tortoiseshell outer case. There is an area of damage to the tortoiseshell as shown in the close-up photo, together with a 5mm crack on the opposite side. There are various papers in the back of the case together with the painted name of the original retailer, A Solomon of Norwich and Boston.
