Other Details

 

NOTES:  The Breton has been seen with a variety of dials, including all numbers, full index, and with and without the seconds subdial.  The case was also made with and without engraving.  Such variety within the same model designation is typical in the mid-to-late-1930s.  The Breton can be distinguished from other, similar models through case and crystal shape and dimensions.
