During the end of 1960’s and 1970’s, when many watch manufactures were understandably concerned about the threat that quartz accuracy posed to their mechanical watch businesses, some of them developed hi-beat movements in efforts to push the boundaries of mechanical movement accuracy.
Today, when watchmakers in service use extra good quality oil, not need extra – often maintenance. Not in mass producing today because this movements need special and extra good parts, this not can be default solution – standard for today watch industry. But, this movements have best accuracy…”
