Buren

Swiss Watch Fair 1964
The new Buren 65 movement, fitted to this watch combines the best advantages of round calibers (6 ") and shaped calibers ( 4 n) 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 Isochrori index-assembly. Additional advantage : this small movement has a 52-hour power reserve. (BUREN)
