Gold and silver watch cases were also stamped with Dennison's registered sponsor's mark ALD or A·L·D in order to be sent for hallmarking - the assay offices required the sponsor's mark to be composed of the two or three initials of the "responsible person" at the company, a company name or trade mark was not acceptable. Dennison made two grades of gold and silver watch cases, "standard" and "special"; "special" indicating thinner material.
