When I don't need to carry a bag: Phone (back left pocket), Wallet (back right), Gum (back left again), Keys (on a keyring attached to a belt-loop, with a retractable wire), Watch - with a pretty garish blue face. I should change it. With a bag, a brown leather messenger bag I carry 90% of the time: All of the above, and Moleskine x2 (notebook, planner), Pen (Watermann gold-nibbed fountain pen, vintage from my father, not sure of the model), More gum, Zippo lighter, Train timetables.
