Who says you can't find anything good on Ebay anymore? Got this gem a few weeks ago. I really liked it due to the racing nature of the piece and I had never seen one before so the bidding was on.
The black plastic case is about 4.5" x 2.25". The two watches are smaller than the normal Heuer models we usually see. The silk screening on the right one is slightly different than the other as can be seen in the winged Indy Logo.
I think this piece must have been a general sale item at the track due to the small watches and hard plastic case.
I posted a while back about another 3 second sweep stopwatch I own, and this one is cool with dual watches. Man, do those hands whip around when started. You can really see how long a second actually is.
All in all, a very interesting piece.

PS. I'll admit I do think I over sharpened it a tad while post post processing.
