·I have also this picture but it seems more a 2000 series
I think that might be a watch that he wore during the latter part of the '87 season with Lotus. He looks younger and his hair style is more like his Lotus years than McLaren. If so, it's not a 2000 or even a TAG Heuer.
I've been trying to make a positive ID on this watch for a while but haven't yet. I think it's possibly the same watch as in your pic.
