Question re. accuracy of watch if not worn
I wear my JLC only on weekends and for the rest of the days, it is just sitting idle running. Is it normal if the watch starts to consistently gain / lose time if it sits in the same position (eg. on side) for 5 or 6 days straight? say, gain 1 minute in a...
Quite possible indeed. And a minute a week is only 8.5 seconds a day...
...which is not totally unheard of. Try resting the watch in a different position and see which offers minimal deviation in accuracy. Here's a little, non-scientific experiment I did with a new Omega movement. And here's a printout from the machine which ...
re
The 1000 hr control is supposed to be even stricter than COSC, Im not sure if it gets tested based on 1 position for a day, or rotating in different positions throughout the day and then the deviations gets measured...

That rate for the Omega looks excellent....
only varying between +1 and +3 over the five tested positions. Very accurate Omega you have there. Simon This message has been edited by sclamb on 2012-02-24 18:02:28
Thank you, Simon. I was quite surprised myself.
The only watch in my collection which is more accurate is the Grande Reverso 976 at about +0.5 second a day. All my other watches are like +3 or +4 seconds a day with one exception being my 2009 Omega Seamaster Ploprof which loses 3 seconds every day righ...
If the gain is consistent.....
then your watch is fine as the rate and amplitude should be consistent in any one position. As you can see from the Omega printout the rate and amplitude vary in different positions as you would expect due to the forces of gravity on the mechanism (of cou...
Slightly too fast.
I would re do the settings, which is normal, by the way, as even if it is adujsted to several positions, in the real life, it may change depending on the wearer's style of life. So it is not anormal that after a while, you can see this. This is easy to se...
probably u can consider getting it serviced. mine gains +15 seconds a day!!!!!!!!!!!!!!
Mine gains +15 seconds a day now!!!! Home.watchprosite.com Anyway 3 seconds/day is the "minimally acceptable". This message has been edited by xsw on 2012-02-25 03:55:48
