Story time:
A friend of mine was going to Moscow, about 25 years ago. He had a $35k IWC watch on his wrist, and suddenly got afraid that he might be robbed of the watch, so bought a $20 Casio watch in the New York airport. When he arrived in Russia, the customs official asked why he had two watches, accused him of planning to sell one of the watches, and stated that he was confiscating one of the watches. My friend was horrified to think he would lose his $35k IWC...
Until the customs official said he was confiscating the $20 Casio, along with its box and instructions. My friend spent an hour helping the customs agent use the watch, and translating the instructions. The customs agent was overjoyed to have a new Casio watch, and my friend was overjoyed to not lose his fine watch.
