Yep, the 3510 automatic that has an ETA 2892 with a DD chronograph module on top. Notice how the crown sits on a different plane than the pushers?
I thought it was a fake because I didn't realize that the automatic looked different to the manual ( oops!)
Very simply, a smaller automatic Speedmaster as you see in Ulackfocus' images. Do a google search for the name an you will find more info than you want. Also search eBay and you will fine many for sale. Quite common a few reference numbers for the basic but most people mean the 3510.50. There are many forms of the Speedmaster though.
