Glasses, Watches, Cell phones and pagers

Leave the cellphones and pagers in the car, you cant take them with you. However a cleverly concealed camera is often a nice to have, just be careful where and when you use it. You are permitted to wear a period watch only, no new digital watches. Your glasses should be wire framed period glasses.
