Dorian is really dumb. In many European countries north-african criminals will shoot you in the head or stab you for a 5,000 euro Rolex. Not to mention an 18K watch. Or they assault your house to get your watch collection while your wife and children are there.
They follow watch owners on social media so they often know what you have and when you are away for work.
Not to mention that luxury timepieces are innocuous and highly liquid tools for money transfer operations.
There is no oversight or registration for timepieces
A highly unregulated, and fragmented gray market makes converting wristwatches into cash relatively easy.
Many watch dealers are more than happy to purchase these items below market value and not ask questions.
