The Breguet museum, under the auspices of Dr Nicolas Hayek, president and CEO of Montres Breguet S.A., purchased the most important horological document in existence for a record-breaking CHF 2.3 million, creating a cliff-hanging end to Patrizzi & Co’s 7 May Geneva auction. Thanks to a total commitment and aggressive bidding, the Breguet museum ensured that this historic manuscript has finally returned home.
