I don't usually wear a watch - do you? The two exceptions are when I'm traveling (no one wants to miss that connecting flight...) or when I'm teaching. I've recently taken up tutoring again, which is code for "having fun with little kids at France Exchange in Los Angeles," so I pulled my watches out of the drawer.
Both are very precious to me. The elegant yet sporty Tag Heuer model was given to me by my generous parents on the occasion of my 20th birthday. The other one is an Omega that is quite ancient since it goes back to the days when my father was a young man - he bought in 1965, in Dakar, Senegal, where he was then living... Unlike the Tag, this Omega is a mechanical watch, meaning that it's powered by the energy from your wrist rather than a battery; every time I use it, I just adjust the time, shake-shake-shake my wrists and it's good to go. Very environment-friendly. Magical.
