Well just because I haven't seen it doesn't mean it isn't out there.  This one is just too cool.  It's stated as a stainless steel case, sporting an 11 movement.  It was called "bull head automatic", and the first thing I thought was bull#*%!, but after looking a little closer, I can see how someone would describe it as a 1970 Bulova Bulls Head Chrono.  Case diameter listed as 42mm w/o crowns.

Yep I saw that.  The watch Dr uses for his "representative example photo" is a Heuer Cal. 12.  I see this family of movements includes 11, 12, 14 and 15 calibres. Subject watch is 11. 

I can't see where the microrotor would be located...and I don't know.  Does anyone esle know the appx. location of the micro rotor in either of these exampl movements?

It is buried underneath the Plate, on top of which you see all of those Chronograph Parts in the photo.

It all has to come apart anyway during a Service!

Thanks for the info.  It must take a true master to service these things correctly!  I can break things just trying to get dials off for photos of the back....  That's why I've learned to send them to folks like you!

It looks like 14 when the pic is blown up.

Darren - not sure if the 14 EFAD is the mvmt pictured above. This is not my watch, or my photos ( I snagged them several years ago from a listing by ebay seller 'watchcollctor4u')

Crown at 9

movement photo - looks like 14 EFAD to me

 

Sorry plains, guess you're going to need one to these too!

Here's another 'style' looking more like a 1960's Diver.

Case # 7605 is a Compressor design with very interesting Caseback markings as it is stamped Bulova and Heuer Leonidas sa, the movement looks like a 14 linge (EHAD) Dated 1964.
