The subject what presidents wear on the wrist is amusant.
The Vulcain story, when Truman get his Vulcain Cricket the staff and friends changed Pateks and Rolexes for a Vulcain watch.
The work Jack Heuer did to get a Heuer on the wrist of a Kennedy.
A Heuer on the wrist of Steve McQueen -monaco- is another story.
When Jack saw Obame wore a Tag Heuer, he was so happy, it was an achievement.
Back to Joe.
It is remarkable he wear a Rolex Datejust. If i recommend a watch for him as i study his public appearance than i can say a JLC Reverso is perfect. Not too big, art deco, and is a good watch when wearing a quality suit.
The first lady, let’s say a Roger Dubois with a light blue dial, white gold case.
update: i wrote a Kennedy. Robert Kennedy.
