Silver Hallmarks

Silver Case Hallmarks

The hallmarks found on William Bent watch cases are the most reliable means to determine the age of the timepiece.
www.925-1000.com/british_marks.html is a great reference site for deciphering English Silver symbols, date letter codes and maker’s marks.
Here we examine the silver hallmarks on two watches.

William Bent Serial # 12635
The hallmarks photographed here read as follows:

The Silver Standard Mark – the lion passant (walking lion) indicates that the solid silver case has been tested and is at least 92.5% pure silver. This is the purity mark for British Sterling Silver.

The City Mark – the leopard’s head indicates the case was tested at the London Assay Office.
(The majority of leopard’s head marks are so worn they look to me like a skull and crossbones – however 
the second watch displayed here shows an almost mint mark on watch #12635)

The Date Letter – lower case “r” for 1872 on watch #13285 and lower case “q” for 1871 on #12635.
The date letters can be read from the chart:

The Maker’s Mark – “R.O” (not “B.O”) is for Richard Oliver, silver watch case maker, Galway Street, operating in St Luke’s, London 1864-1873 (registered 1859) www.silvermakersmarks.co.uk

The Serial Number – William Bent watches so far discovered have serial numbers ranging from 8631 to 18410 (View them in the Catalogue). Numbers are sequential, but I don't think they started at #1.
Matching serial numbers appear in five places on a William Bent watch: twice on the case; on the dial; on the movement and on the dust cover.

  1. Very Informative blog! This blog keeps very informative concepts of sterling silver hallmarks. The marks on the bottom of a piece of silver can be an indication of the age, maker, and origin of the piece. The first thing you will want to do is to clean the Sterling Silver Flatwarethoroughly so that you can more easily read back stamps and markings.
