Bulova 1960 Beau Brummell

Another example of how Case Colour affects a Model variant designation, reguardless of how the vintage advertisements read. 

So are we identifying my watch as 05735 Y Beau Brummell "DDDW"? Where can I see this example? Or is this it? Are we back to 2 LL's & not one. I have a jeweler near me that is going to open,clean, & oil it in the new year, anything in particular we should look for?
