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 were not done this way, they honor human craftsmanship in the production process whenever possible and were usually assembled and regulated by three or less watchmakers in the entire process.
So human factor will always be there. While under most circumstances not a bad thing at all but slight variations in accuracy across different pieces is in fact to be expected.
Think of it as an unique touch. After all , high level of consistency in outstanding craftsmanship is what we're ultimately after. Not quartz accuracy, we already have the indestructible Casio for that exact purpose ;-)
And in fact a highly consistent +5s/day is a sign of outstanding craftsmanship, maybe the watchmaker regulated your piece on a slightly cold day so lubricant and spring was abit stiff hence the slight gain in warmer climates, not really a worry in my opinion.

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...

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 ...
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...

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 ...

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 ...

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...

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...
