NOTES:  This model is difficult to distinguish from the Governor, but crystal specs provide guidance.  G-S Crystal Catalog 1937 lists the Lafayette as taking the crystal specified above, which is noticeably narrower than the crystal used by the "Governor".  It should be noted that other models take this same crystal, including, at least, the following:

  • Lone Eagle (II)
  • Richard
  • Edwin
  • Dewey
  • Lafayette


We have advertisements showing all the known models that take this crystal.   We also have confirmation via crystal catalogs for all listed models except the Dewey.


As with other models that originated in the 1920s offered in white gold, we see a slightly later yellow gold version like this example.  Note the matching yellow gold movement block and dust shield retainer ring.
