Please help identify this 4111.....

Why there is no stainless steel sign in the case? Thank you!

Welcome to the Forum.

The watch is a Reference 4111 and details can be found by cutting and pasting the following into your browser (the link function for this Forum seems to have gone missing), it is a link to the 1980 dealer sheets.

Not sure why the case is not marked stainless steel.

Hope this helps.

Cheers from the cellar

Dont think you need to worry. I have seen many vintage steel watches without the word steel on them.
