HeadphoneAddict Posted February 25, 2015 Report Share Posted February 25, 2015 My Citizen E820 movement based perpetual calendar chronograph only gained about 0.0167 seconds a day for the past year. 6+ seconds a year still sounds like a lot, but that's what many mechanical watches can gain in one or two days. 1 Quote Link to comment Share on other sites More sharing options...
