Your watch ain't magnetized bro.. don't worry..
A magnetized watch runs minutes fast a day (not seconds)..
As for the 5 seconds or so fast per day, like some have said, it's within tolerance.. Have u been winding it at the same time daily? I say so because most watches are adjusted for isochronism to 24hrs.. Meaning, if u have been waiting, say, until the tail end of the power reserve before winding it, the rate may be off more than desired...
A question on accuracy
My 1815 seems to be running a little faster than I expected....to be exact, it has gained 91 seconds over a period of 17 days, which works out to about 5.3 seconds a day. While still within standards, I\'m wondering if this is normal, especially for an es...
It is not a Chronometer, and it is within Chronometer specifications. So, all good.
About the statement that a watch has to run for a few weeks before being let's say accurate, that's true. It has been confirmed to me by several watchmakers. Best, nicolas
But they passed the
accuracy tests before they left the factory. I think the break rumor is just that, rumor.
Perhaps things are slightly different in a controlled environment?
Just thinking out loud. On the wrist, there are elements that probably can't be simulated as well in factory testing.
Agreed on keeping it for a few more weeks
...though I\'m still divided on the deviation rate. Quite big, IMO. Will see if this improves over the next month or so
If it was me
I would send the watch back to your AD. The daily tolerance for a Lange is +3 -2 so your watch is working way too fast. Lange, Patek and Rolex currently produce watches that way surpass chronometer levels by twice or even more. For many accuracy may play ...
As important to me too, the timekeeping rate
But I think I will let it run for a few more weeks. I have some vacation and business travel over the next weeks anyway, so I might as well try that run in theory. My view is that all tests run thus far would be in a controlled environment, which is quite...
A change from the norm or not
Richard, It is not clear if the results reported are a change from previously better results i.e. change from the Norm or they are the first results that you measured from new. If a change, consider magnetism. On a binomial distribution curve, somebody ha...
I suppose this is the norm to me
I set it at the shop when I picked it up to my reference clock, so if any magnetism occurred, it would have been before I picked it up. Anyway, I\'ll do that run in and see how this pans out.
I would keep wearing the watch
You have a mechanical item that is supposed to work properly for years in all sorts of conditions. Give it a chance to prove itself to you. Let it run down. Sit in the drawer one day not running. Wind it up and each night put it down a different way - dia...
Thanks for the suggestions
I will try some of these. I honestly wasn\'t paying attention to time keeping as I don\'t usually do, at least not on a daily basis, but I happened to check yesterday against my reference clock, and it look further out than I expected it would be.
I think it's alright
but u should try different positions when u r not wearing the watch eg Dial up.. to see if the +5 can be offset
Planning to do just that
Have re set it this morning to a Watchville app timing and will see how the additional positions and weeks ahead changes things, or not

Thanks for the added input
And yes, I wind it pretty much the same time every morning. Let\'s see what the next few weeks yield.
You don't have to worry.
5s per day is a good rate... at this stage, I will keep it as it is. Fx
After 5 months....
This has not improved and it has bothered me more than needed. Had a good meet up with Sham1 over lunch and he confirmed what I should do...send the watch back in to correct the +5.2 secs per day. Yeah, my OCD was just too much to ignore. Let's hope this ...
Well
Mechanical watch is like micro machines and to be honest, best accuracy is usually achieved buy using high percentages of state-of-the-art-robotic works in the production / assembly process like Rolex . But A Lange , and many other haute horlogerie pieces...
...
And the funny fact is that in my case, one particular non-certified , non-adjusted ETA based dress watch (by a reputable brand) that I owned for the past 10 yrs is running at a steady less than +1s/day. Blowing all my new and old Poinçon de Genève , COSC ...
:-) trying, but my OCD gets the better of me
As for ETA based, they run perfectly so consistently, I've learnt that in house is not necessarily better. My Tudor Black Bay with the ETA movement runs +2 sec fast every 20 days, which is superb, in my view.
.....
While Tudor is mostly ETA based, they use first grade base units and 'rework' them to a much higher standard. Not very difficult to understand after seeing all the 'crude' looking Rolex movements with near quartz accuracy. The little linen dial I purchase...
Richard N , this is not your first watch....
so some patience is in order my friend I also think you should check it once a month if it does not improve and you have better expectations. Report it on the next service in five years. In the meanwhile enjoy your beautiful piece. Best Regards Edward
I've kept it going to nearly 5 months and I just can't take it :-)
Sending it in to Lange today....it is seriously annoying when because my PADI Turtle runs more accurately - I expected it to run relatively accurately, but given the price point, I was willing to make some concessions - it has exceeded all my expectations...
You have been terribly patient Richard!
I would have sent it back after two weeks! Afterall the watch had undergone lots of tests before leaving the factory and I doubt if the trip to Malaysia would have affected the accuracy of the watch that drastically.
。
In my opinion consistency is more important than objective accuracy. By that I mean a piece that's running at a steady gain of 5s per day is IMO better than the one running inconsistently at a -2/+4 range. This is especially the case if the piece is 5 pos...
I do agree with you
It is with the service center now who will look into it. Hopefully it will be a quick turnaround
Just compare it with the last
official testing limits of German Naval Observatory (Hamburg, 1940) WBR Serge ...
