I tell ya what and you do as you think but I would put a one piece NATO band on that Rolex for your trip and then switch back to the metal band for the board room when you get back. You will feel really stupid knowing it is lying on the bottom of the ocean due to a pulled pin. Ask me how I know such things--on second thought don't. The nylon NATO/military type bands reduce the "profile" of the watch also making it look more common if you get my drift.
