九十年代初，著名的日本双狮表用的红宝石是我国烟台一企业为其制造的。一段时间后，日方技术人员到烟台要求我方“将红宝石的质量标准再降低一些。”令我方工作人员大惑不解。后来才弄明白，日本人要求的是与其手表整体质量相匹配的红宝石的质量标准，某一零件的质量标准过高，? The early nineties, the famous Japanese double lions watch Ruby is a business for our manufacture in Yantai. After a period of time, the Japanese technical staff went to Yantai and asked us “to further reduce the quality standard of the rubies.” This puzzled our staff. Only then did I understand that the Japanese demanded ruby ​​quality standards that matched the overall quality of the watch, and that the quality standards for a particular part were excessive?
