Nice one buddy, really clean.
Date King, unknown variant.

Great advert find Bobee!!
Bulova Date King for me too. An uncommon square version at that.
Date King it is, a nice one too.
+1
Thanks again guys for confirming the ID of this one. I wonder what that rectangle is over the sub-seconds hand in the advertisement is. I've seen more than one ad for this model and they all have that.
Nice watch! Not sure what that rectangle is.
Date King.
Nice Date King! Typically they are seen in the round case, not too often in the square; and I've always wondered about that area above the sub seconds too.
Date King for sure.
