Before I read this Financial Times article by Bryce Elder, I didn’t know:

• That ‘Trump’ branded watches existed.
• That anyone would try and sell such watches for $100,000, let alone successfully.
• What a “tourbillon” is, “and, though it probably does nothing, people appreciate the extra engineering required.”
• That a 75% gross profit margin on a luxury watch is not unusual.
  

Every day is a school day.
