Indeed, the question of "which watch?" has been an important topic of discussion here in the US of A.

I have checked the photos, and can confirm that he wore the "Secret Service" watch, both for the actual inauguration and for the balls, during the evening. The watch looked a little strange with the tuxedo, at the balls, but it looked perfect while he took the oath, with his left (watch) hand on the Lincoln Bible.

Of course, I was hoping that he might switch back to the TAG-Heuer for this historic day, but he stayed with the Secret Service watch, which he has worn for apporximately 18 months. I suppose this one has become the "lucky watch".

Here is an item of trivia for you: there are exactly 12 of these watches, produced with the Secret Service logo; Obama has one, and I have one . . . maybe we start a registry to try to find the other 10? Unfortunately, the knock-offs have already arrived (selling for $325), but they cannot have the actual Secret Service shield.
