I personally don’t see the above 2 models as dressy. They were designed to be “sports models”.
A PSM is a great choice. If you can find an enamel Picadilly or Serpent Calendar - go for that. They dress up beautifully.
I wear my 38mm Serpent Calendar wit a dress shirt regularly. Fits under all cuffs (except French cuffs of course) and is a delight.
