He became obsessed with watches in his early youth, and - against all advice - he decided to wear a wristwatch. He acquired a Rolex and an Omega soon. The one he got as a present from Mr. Roosevelt was actually a Patek Philippe, and a complicated one... I think he never wears the PP, though. Repairing mechanical watches (with various degrees of success... - his own words!) is still one of his favourite occupations.
That's all I remember from his autobiography for this topic.
Have a nice day,
