Here is a one for the Sinn fans, which I am owing a nice Tigmented 756 chronograph.
The NASM holds the Sinn watch worn by Alan Eustace that he wore during his record breaking free fall jump from 25 miles lasting 15 minutes.
His watch can be seen here in the NASM online collection.
I had the great opportunity to spend two hours with the curator of one of the NASM collections this past week and as we walked the floor she pointed out Alan Eustace's free fall suit along with his Sinn watch.
Here is his watch as seen online in the NASM collection.
Here is the suit I photographed yesterday and the watch on display.
Here is Alan Eustace's record setting jump for those not familiar with is accomplishment.
