GB/T 33727-2017Analogue quartz clocks -- Fitting dimensions of movements to hands (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the translation method equivalent to ISO 13074..2012 "pointer quartz clock and heart with the pointer size".

And the normative reference in this standard international documents are consistent with the relationship between China's documents are as follows.

Geometrical product specifications (GPS) - Limits and mating - Part 1. Tolerances, deviations and mating - GB/T 1800.1-2009

(ISO 286-1. 1988, MOD);
