My First Jump Hour

I fell in love with the look of this watch as soon as I saw it. I've never seen one before and haven't found many on the web. Mine is only in Nickel Chrome, not platinum, silver or gold, but who cares? It's marked Seeland Watch Co. inside the case and Mormac Watch Co. on the movement. Also inside the case it has 'BREV. DEM.' with a Swiss cross. There are a couple of numbers engraved on the outside back of the case as well. Anything anyone can tell me about this watch would be of great interest!
