In 1946 Montres Dreffa, SA registered the name Dreffa Watch  in the USA and started selling its luxury watches in the USA under the Dreffa name. The logo was changed to include the word Genève. However, In 1975 during the quartz crisis Montres Dreffa, SA suffered along with hundreds of other Swiss watch companies and reduced production of its fine watches as the market for mechanical watches declined in favor of quartz movements. The factory was based at 30 Rue du Stand, Genève
In 1985 Jacques Maguin acquired the Dreffa brand and updated the logo to include a D with clock-hands inside at 10:10.
