fitmic Posted September 6, 2007 Report Share Posted September 6, 2007 Quartz movement loses 10 sec per month. Is that acceptable and/or normal? Quote Link to comment Share on other sites More sharing options...
ximenes Posted September 6, 2007 Report Share Posted September 6, 2007 That's all it loses? Pretty accurate Quartz... indeed! Quote Link to comment Share on other sites More sharing options...
Dizzy Posted September 6, 2007 Report Share Posted September 6, 2007 i would assume thats normal.. especially for a battery causing a little crystal to vibrate... I never really thought quartz watches were super accurate but then again i havent owned one in 15 yrs so i dont really remember...

offshore Posted September 6, 2007 Report Share Posted September 6, 2007 @fitmic, It can probably be pulled in to a fair bit better than that.... but is it worth the time/cost? Gee my daily beater (mech) is 3 minutes/day slow, and I just reset each morning! I have managed to get some quartz movements ( Swiss ) to 1-2 seconds a month.

fitmic Posted September 6, 2007 Author Report Share Posted September 6, 2007 Why I was asking this, is because I haven't bought a quartz for >10 years, so I can't even remember. My brother is about to buy a brand new watch, and the watch salesman says it loses or gains 10 seconds a month. Thanks for the replies.

Corgi Posted September 6, 2007 Report Share Posted September 6, 2007 I had a quartz movement that lost several hours a day... turns out the battery was nearly dead. I think with these types of movements accuracy is directly proportional to battery quality and health. Chinese batteries inside most of our quartz reps are usually very very unhealthy.

dachshund Posted September 6, 2007 Report Share Posted September 6, 2007 I have never owned a quartz that has been close to 10 seconds off per month, most have been some where around 3-4 seconds per month, others 1-2 seconds per month.

I have a $40 casio that is designed to be plus or minus 20 secs a month, less than a second a day. 10 secs a month is pretty good, I think, but not unreasonable.

JuiceMaker Posted November 17, 2007 Report Share Posted November 17, 2007 just a thought... what do you guys measure the accuracy of your watches with??? suppose you have a truly "accurate" watch & you measured it against another time-keeper that's NOT accurate, then it will lead you to believe that your watch is NOT accurate, but it reality your watch is truly "accurate"... know what I mean??? is there some time-keeper that is supposely to be the most "accurate" of all???
