• The works for drawing up standard on the accuracy indication for quartz watches and clocks are going on in Sub-Committee (SC11) of ISO/TC 114 (Horology). The purposes are to unify the method of the accuracy indication and the related test methods for the accuracy of quartz watches and clocks internationally and to prevent unreasonally overrated indications. Proposals for the establishment of this standard have been submitted to the SC11 from Japan (N10 for watches, N11 for clocks), from Germany (N12 for watclhes, N13 for clocks), and from Switzerland (N24 for watches ). The present paper gives the results of an experiment conducted at the JHII for examining and comparing these proposals in practice.
