Smiths W10 & 6B - cases by Dennison?

[Rev-O]

Hi All

Were the Smiths W10's cases made by Dennison ?

I believe that the relatively rare 1950's / early 1960's GS Smiths "De Luxe" was in a Dennison case (although I may be wrong about that). But what about the W10 / 6B from the late 1960's -- are they Dennison? Or in-house? Or . . . what?

I think that most, maybe, all of Smiths' civilian waterproof watches throughout the 50's and 60's and were in Dennison, usually the various revisions and versions of the Aquatite case, but is the W10 in one as well?

Thanks

Just seen on wikipedia that Dennison stopped making cases in 1967, so to answer my own question: probably not!
