NOTES:  I have quite a collection of these very similar, rectangular models from the 1920s.  I'll do my best to compare them here.  This model is very close to the two watches that I have identified as the Windsor, but it is a little larger.  At this point, I don't know which of the two different versions is the Windsor and which is an unknown model.

 

This Model: 

  • 36mm x 23mm case dimensions
  • 23.5mm x 17.8mm crystal dimensions
  • berry and leaf pattern on bezel with a single flower in center on all four sides
  • mitered corners on bezel
  • 14K GF
  • 15 jewels

1926 Windsor and 1928 Windsor

  • 33.4mm x 21.8 case dimensions
  • 22.3mm x 17.4mm crystal dimensions
  • berry and leaf pattern on bezel with a single flower in center on all four sides
  • mitered corners on bezel
  • 14k GF
  • 15 jewels
  • 36.4mm x 24.1 case dimensions

  • 24.5mm x 19.2mm crystal dimensions

  • arrow patten on bezel with a single flower in center on all four sides

  • straight (unmitered) corners leading into lugs

  • 14k GF

  • 17 jewels

Two other somewhat similar models are the:  1929 Dictator and 1929 Unknown, but they have a noticeably different engraving pattern on the bezel, and the Dictator case is curved rather than flat.

1928 Unknown
