I picked up a copy of Motorsport magazine the other day. I'm not a huge Motorsport fan, but the historic articles are usually interesting. What struck me was this; they had a 20 page "advertorial" supplement with about 20 current watch manufacturers trying desperately to associate their watches with the image of car racing, including TH with the Mcqueen pic and the photoshopped new Monaco (stupid marketing decision). None of it felt remotely authentic. But then you turn to any random article about motorsport in the 60's-80's and you see photos of Heuers on the drivers, mechanics and team managers ..... real authenticity rather than paid adverts....

Sorry if these photos are too well known, but I didn't know them. There was an article on Alastair Caldwell, who started at the bottom at Mclaren (great story) and rose up to team manager. In the article there are a few photos:

Alistair with a Pasedena (or maybe Porsche design):

Another shot (the bracelet does look maybe PD?):

In this one Alistair has what looks like a art deco watch but the guy next to him looks like he's wearing a Calculator:

If you like the photos, go to his website, it has a lot of cool photos and info (http://www.alastaircaldwell.com/)
