Geoff, I'm going to use Yor NOS image if I may.

The 'DEEP SEA CHRONOGRAPH' "B" has an identcally calibrated Dial as the subject Watch, only the color scheme differs.

The "Supercompressor" Dive Case of the subject is the same as found on all 3 'DEEP SEA CHRONOGRAPHS's listed in the database.

The 14 EB movement of the subject matches the movement found in all 3 'DEEP SEA CHRONOGRAPH's listed in the database.

Oh dear, fancy having to use a variant letter to show the differences in watches!

Ya, unfortunately the subject Watch is not the 'B' variant.

The subject is the 'DEEP SEA CHRONOGRAPH' variant unknown.

simple enough.

This can be seen as a comparison with the recent American Clipper "F", in that it is the nearest to a correct ID.
All that Mark says above about the dial, case and movement is true, and apart from his bold statement that it "is" the Deep SeaChronograph, I agree in that it is the "nearest thing" to an exact ID we can make with the information we have.

The subject movement is a Chronograph and the Super Compressor Case is depth rated to 666', as indicated on the Dial.

"DEEP SEA CHRONOGRAPH" -  variant unknown

Fifth - I don't think any off the three similar watches currently under review are using Brevet Super Compressor technology.  Brevet patents were on watches using this technology, and I'm not see them on these three watches. Maybe the Brevet patent info is on inside case backs, and we don't "know", but I don't remember any Brevet patent stuff on the inside case backs.   May not impact the ID names, but wanted to note this possibility. 
I can't find the one thread/forum post or watch record where we discussed Brevet technology, but there was a depth rating that Brevet gave (like 630 feet or so), and we discovered that Bulova extended their ratings to 666 feet- sort of took poetic license to do so as a marketing ploy.  By doing so, perhaps after a few years of both Brevet and 666 feet on watches- Bulova chose not (or could not) use the propitiatory Brevet technology, which was only rated to the lessor depth.  The early 1960's Bulova watches, maybe '60-'64, had both the super compressor technology (including the patent stuff) and the 666 feet on the case backs/dials, but then after c1964ish, Bulova stopped using Brevet technology but continued w/ the 666 feet thing?  I did find this thread....http://www.mybulova.com/watches/1963-snorkel-666-4236

Its not published as a Deep Sea Chrono Will, so it will need to be changed to Deep Sea Chronoraph.
