NOTES:   We have two early ads showing Bulova watches in Wadsworth cases, as discussed in Searching for the Beginning.  Additional details about the Wadsworth case company are 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.
