The new Buren 65 movement, fitted to this watch combines the best advantages of round calibers (6 ") and shaped calibers (5 ’O and thus enables the use of a wide variety of case shapes. The balance wheel, which is screwless, has a high rate (21 ,600) giving great precision. Repairs and adjustments are also made easier by the new Isochron index-assembly.
