London is one place where you will never feel overdressed wearing a suit and tie day and night. For the
classroom, though, you could probably get away with anything, but you are a style forum member, so I expect you will make more of an effort than will be expected of you and your classmates.
Check out coolvintagewatches.com and Father Time antiques to see other options in vintage watches-you may be surprised at what is available in your price range, even some fine solid gold watches with manufacture movements, such as Lecoultre, Longines, Gruen, Universal Geneve, and Movado (back in their quality days).
It is true that cheap sunglasses lenses can increase your eyes' exposure to harmful UV rays.

On the John Lobb (St. James's) website, in the black and white catalogue from the 1930's, there is a picture of a "Tuxedo Slipper" which is a Norwegian slip-on.
