Other Details


NOTES:   We now have numerous ads and trademark information establishing the Rubaiyat as a Bulova product, as discussed in Searching for the Beginning.  Information about American Standard signed cases is included in Bulova Case Signatures.  The basis of the date assigned to this watch is explained in Dating a Bulova, which now includes a detailed timeline for assessing watches made prior to 1926.


This is the second very early model in my collection that appears to have a rose gold case.  Below is a comparison of this watch with other models in my collection:


         Rose Gold                   Green Gold                 Rose or Coral Gold              Yellow Gold
