Fantastic black dial on this old guy... found paired with an Omega that also sported the same black dial... might have been done at the original owners request.
The 17 Jewel, 7AP movment runs and sets smoothly. It has a
Jerin,
NICE ONE!
See also the (21J) design... and my comments, thereafter...

(17J) 40s: Broadcaster, Time King "A" (21J) RMS124-15 CMX2120 177 C213/4 177
This model is known by two names, the Sponsor in this 1942 ad.
And the Broadcaster in this 1941 ad.
These 21 jewel models may be time kings.
We have a 1941 Spanish ad for 17 jewels as a "Sponsor". Could be a name used in the Spanish ad. Then we have yet another ad showing a Broadcaster w/ 17 jewels. The model lists I found suggested there were both rose and yellow Broadcasters,however the lists didn't give jewel count.
I starting to think by various crystal specs and existing ads (and to a lesser extent watch examples) the 21 jewel is tentatively the "Time King". Food food for thought.
One tick for Time King based on the 17 jewel count for subject watch. There's at least three variants of 17 jewel Broadcaster (A, B, C, and no variant), so subject watch could be one of those variants with this black dial....and I can't find any ad for a Time King.
And check the dial pattern for subject watch when compared to the two other 17 jewel Broadcasters we have in the database. Same pattern but in black finish.
