Smiths Cases

Sunday is usually a rest day...but as Sunday lunch is complete I thought I would share yesterday’s arrival and ask fir your help!

It‘s a Smiths Deluxe. Now I have come across 3 others with identical cases. None of them appear in any Smiths books or catalogues I can lay my hands on. Their designs are all ‘unlogged’ but with the identical cases I am sure that they are legitimate ‘Smiths’.

my question to you is...does anyone have any Smiths watches with these cases and can anyone shed any light on them?
