Georgian gilt and enamel protective case for a verge pocket watch c1770

I am presuming that this is for a pocket watch, however I cannot see any allowance for a stem.

This is a gilt metal case which would have been for an expensive enamel or gold verge pocket watch circa 1770

The case would have had a glass back which would have protected the enamel or gold case while still allowing it to be visible

The case has carved edges with enamel panels. There is some minor enamel loss and the gilding has worn with the gilding now brassy in places

The catch works well but is missing its button

The case measures externally 65mm wide, 55mm internally x 10mm externally deep
