watchlover321 Posted October 18, 2006 Report Share Posted October 18, 2006 It's just like any mechanical contraption: the more gears you exercise, the more gears that will wear out.. sooo use it sparingly Hi ive recently got a Tag link chrongraph from josh and as you will all know, the second hand that permantly sweeps is the 9 o clock subdial. would it damage or affect the movement if i left the chrongraph running all the time?i like the look of the big hand moving!!! cheers steve Link to comment Share on other sites More sharing options...
crystalcranium Posted October 18, 2006 Report Share Posted October 18, 2006 It's just like any mechanical contraption: the more gears you exercise, the more gears that will wear out.. sooo use it sparingly Is this true? I have heard mechanical watches require running to keep oils from drying out and to insure accurate running. Link to comment Share on other sites More sharing options...
RWG Technical Posted October 19, 2006 Report Share Posted October 19, 2006 Short answer - No - you can leave it running for ever and it will not wear it out... For a long detailed answer, see my how does it work posts in my subforum, there is a anal detailed explination on the 7750... With the chrono on, the only extra gears working are the center seconds gear and the 12 hour wheel is released, and each minute the 30 minute counter moves 1 notch... The center seconds has no friction, so it will not wear out, the 12 hour wheel is normally restrained and the clutch is slipping all the time with the chrono OFF, so ON is better, and the 30 minute timer will never wear out, no friction either... So let it run if you like. As for the oils, they deterioate no matter what, it's time that counts (between servicing and fresh clean oil) not if the watch is running or not...

Devedander Posted October 19, 2006 Report Share Posted October 19, 2006 I think it's funny that many cheaper reps wrongly have the running seconds as the big second hand, which makes them stick out as fake... however peopel get the more expensive ones with functioning chrono and... run it all the time Link to comment Share on other sites More sharing options...
andreww Posted October 19, 2006 Report Share Posted October 19, 2006 LOL, it makes me laugh every time someone tells me my watch is busted cause they don't see the second hand moving. A stationary second hand is the sign of a good watch. Let it be young Jedi. Link to comment Share on other sites More sharing options...
frankt Posted October 19, 2006 Report Share Posted October 19, 2006 As opposed to the OLD asian 7750....which don't run at all!!!...I'm about to try the WD-40 gambit on my 212 movement...WTF have I got to lose????....I actually got more than one vintage junker running that way back in "the day"....Not running well, but running, rather than frozen for eternity!!

RG ..And There is The Correct Answer Again ! Thank You ! I can never find that article from you The Zigmeister, whenever I run across this chrono question...and it seems a few days after the air clears,....someone else will post another cloudy myth about this issue....and chronos in general.. Some people are so afraid of their chronos.... but love them at the same time... Sometimes I actually prefer to leave mine running,... I love to see those hands doing their thing..

RWG Technical Posted October 20, 2006 Report Share Posted October 20, 2006 ..And There is The Correct Answer Again ! Thank You ! I can never find that article from you Ziggy, whenever I run across this chrono question...and it seems a few days after the air clears,....someone else will post another cloudy myth about this issue....and chronos in general.. Some people are so afraid of their chronos.... but love them at the same time... Sometimes I actually prefer to leave mine running,... I love to see those hands doing their thing.. I would not say correct answer, but only my opinion...based on what is running or not with the chrono on or off... I leave them running for days, or off, makes no difference at all in the long run... Do not be afraid of the chrono...it is your friend... RG Link to comment Share on other sites More sharing options...
