Lange 1 accuracy

Jun 04, 2018,18:53 PM
 

It's been quite long I haven't purchased a new watch until lately i acquired a Royal Oak Jumbo which I found very reliable and accurate, like it's faster by less than a minute in a day.

So yesterday I'm curious to check the time of my Lange 1 which is unquestionably superb. I understand it's a mechanical watch and there is certain standard as an acceptable accuracy. But today when I check its time after 24 hours, I'm quite surprised that the Lange 1 keeps its time as accurate as merely 2 seconds faster (than the iPhone time) after 24 hours. Have to mention that the Lange is 7 years old now, and I haven't taken it to service yet. Given it's functioning so well, most accurate amongst my collection, I'm not sure there's any urge to have a service. Honestly, I'll keep wearing it until someday it starts to slow down obviously.

the Lange seems to do very fine indeed. However, the Royal Oak seems to be a bit too fast. I would say that everything within +/- 10 sec per day is perhaps just be acceptable but almost 1 min is really too much. Certainly for a modern watch. Nevertheless,...

I would need to check again tomorrow

One can expect such an accuracy from an haute horology piece

Your Lange will be going fastet not slow down, when it shows you that service is due: the balance swings less wide and hence the second is done earlier. Very nice golden L1!

somehow i had the wrong idea that as the lubricant dries with age, the watch will go slow,

which is what seems to happen with my other watches. Thanks for the knowledge regarding the balance swing

It turns out my AP is also doing +2sec per day
