A. Lange & Söhne

Im pretty sure from this photo it shows Bill Clinton with a Wempe Langematic...  

Blowing up the image one can see that this is definitely a Grosse Langematik Gangreserve in platinum, limited edition of 100 issued in 2005 along with 100 in YG and 25 in RG. A truly beautiful piece. When did this photo appear - is it recent? Interestingl... 

But Bill Clinton does like his watches :)

A great president with great taste in watches.
