Mate to Broadcaster?

I've never seen one before & have never seen an advert for it. A fairly rare specimen ...to me anyway.

I own a Broadcaster and when I first saw this for sale online I initially thought it was a Broadcaster.

It wasn't; It's this...

It's curious why Bulova didn't advertise this alongside the Broadcaster.
