Help with accuracy

[exxondus]

My GMTIIc is behaving similarly.. However, I do notice that the position you place ur watch at night (i.e. when you are not wearing)... does matter.
If you place it crown up, it will lose more, if u place it dial up.. its dead accurate...

For me is crown down, lose more. dial up and crown up no diff or even have is probably a sec which I missed out keke...

wanna go together with me to RSC and regulate our GMTIIc

It's the Singapore Standard Time.

I just adjusted mine to follow the time and will check my watch again 1~2 days later......

Watch position shouldn't affect accuracy. The COSC chronometer certification tests the timepiece accuracy in the various positions (and even temperatures), Rolexes undergo this testing, and the certification attests the timepiece keeps accuracy in the various positions.

but but but....this was in the Rolex manual

1. To gain a few seconds, lay the watch flat face-up overnight.

2. To lose a few seconds, lay the watch vertically with the crown downwards overnight.

3. To lose a few more seconds, lay the watch vertically with the crown up.

I time all my watches to a quartz watch and monitor see after kicking off at the same instance, how many seconds each will lose. And i time my quartz watch to my handphone and my handphone was timed to SST. kaisu anot? . been doing that for past month. Every night 10pm sync the time on everything and next night 10 pm see any gain/lost in each position.

the watch is abt 1 year and 1 mth old. Hope isnt too old . First owner and never serviced for 1 year + liaoz but luckily still under warranty if really have dirt. Can ask them remove and re-oil keke....

yup, lose time in all 6 positions. never see it gain de. odd.

If all 6 position lose time then is not oil dry. Normally oil dry will cost at least 1 position to be different from the rest... Like gaining time while the other 5 loss time. Hopes it helps...

I placed my watch flat face-up last night and did not wear it to office today, compared to Singapore Standard Time again and it gained about two seconds.....after 25 hours flat face-up.

[jSkywalker]

Sad to say, my one and only IWC 3717 is much more accurate than my Rolexes....

Rolexes normally clocks about +2 to 4sec per day...

The IWC 3717 clocks +2sec per 7 days !!

[wjunkie]

My watch gained 7 seconds after 8 days. I'm wearing it daily and let it face-up over night. Consider to let it face-down over night occasionally and hope it helps to reduce the gap. Will test it out and see how.

[jSkywalker]

7 secs for 8 days is already very good....

One month gone since the last time I Synchronized my watch to SST...time flies! Just did a wrist check and my watch gained 10 seconds after one month....

I wear it everyday and let it face-up (just my habit....) overnight.
