Just picked up this Beauty. I know there has been much discussion on this particular model. I would like to throw my hat in the ring. The issue is with the Brooklyn Watch Case Company case. Many specualte that because it is in this case it is not a legit Bulova. The BWCCo was in decline in 1928, and was most likely liquidating assets. It had stopped production and would later lease the factory to....Bulova. It stands to reason that since both companies were in Brooklyn there could have been arrangements made to buy out old products, etc.
There have been quite a few of these hitting the market and I think it is a great example of an early center second hand Bulova.
