I have a nurses watch but I have no idea what the date mark means.
It is marked with the london assay office, but the only date mark like the one on the watch is a Birmingham one?!
The watch is also marked with LS (Looks like the Leon Steiner one, but it is not stamped too well on one side.)
There is also the .925 mark.
Any help to what the date mark means, would be much appreciated.
