Other Details


NOTES:  The Breton is only shown in the ads currently available without a subseconds dial.  However, as can be seen in the ads for the President during this time period, some models were made with and without a subseconds dial.  This case matches the ad for the Breton, and the crystal specifications identify this watch as the Breton (per G-S Catalog No. 43).
