LMAO the scenario is less clandestine than that. I live a whole seven minutes drive away from my practice.P I imagine that your day starts with you packing 3-4 watches in a pelican steel case and then, handcuffing it to your wrist you walk around holding it. When the need to change a watch strikes you, off you head into a phone booth and swap out the watch and then you carry on your day.
That explains the frequent changes of watches each day. I can imagine no other scenario.
