Dennis, are you referring to the subject watch or another as the subject watch does not seem to have any engraving.

Hi Admin, Sorry I was refering to another watch in my collection that has engraving on the sides
I believe they did. It is sure a beauty Dennis. Admin did the phantom come with a 6AF movement?
The watch also looks like something I just saw in one of the ads. I will have to do some research before I can give my vote.
There is a 21J engraved version of this that is the President model. This 17J non-engraved version is shown here as the Phantom.

and here

As far as the movement is concerned there are no records that say what watch goes with what movement, but I gather from the small width of the watch a 6AF would do the trick.
Similar to, but not the 'PHANTOM'.
The 'PHANTOM' shows much wider horizontal bezel sections.
In reply to Similar to, but not the by FifthAvenueRes…
HUH? much wider than what now? They look identical to the 'drawing' and they are only drawings.
Mark, what model are you proposing?
It's an exact match to the Phantom.
Phantom.
Th ads do not show the curve of the bezel horizontals, which need to be factored in.
KISS
Phantom.
