A. Lange & Söhne

From A. Lange & Soehne, A. Lange & Soehne recommends that you do not do the following to an A. Lange & Soehne wristwatch.  Most of them are obvious, but all of them are serious offenses. 

1.  Swimming with a watch that doesn't receive regular maintenance. 

2.  Wearing metal chains and bracelets and a Lange watch on the same wrist. 

3.  Hammering, golfing, mountainbiking and whatever else will keep shocking the watch.  Over time, the shocks will influence a watch's precision. 

4.  Leaving the watch on the dashboard in summertime.  Quick changes between extreme temperatures put strain on the lubricants, thus influencing the precision of the moment.

5.  Handing a Lange watch in for maintenance service with an unauthorized retailer licensee.  Much damage is caused by improper repairs. 

6.  Correcting the outsize date between midnight and 2 a.m. 

7.  Not setting back the crown by a half revolution after winding the watch. 

I personally follow all of the rules, except on some rare occassions, I am not supremely confident that I fulfilled action # 7.  This is why I posted these rules, so hopefully other A. Lange & Soehnes are not suffering mistreatment.

Hi Patrick:

I hope things are well with you.  Can you please give more detail about rule #7?  I think I know what you meant, but please elaborate.  Thanks.

Josh and I are looking forward to seeing you again whenever you return to New York.

..and helps ensure that the click is engaged with the teeth of the ratchet wheel.

As I understand it, this is recommended for so-called German-style clicks, which have a single "beak" and a spring pressing down
on them.  These clicks, which must both slide and rotate out of the way while winding, are more prone to sticking if not properly
lubricated than a more modern click, which have two teeth and undergo only a rotating motion while winding.

Such is the (minor) price paid for beauty and tradition...

I didn't read your answer while posting mine.

Now I get it.

Thanks!

I completely agree with tee530's assessment. 

Personally, I look at rule #7 as an optional. 

I look forward to meeting you and Josh again the next time I'm in New York.  Hopefully I'll be visiting again soon! 

 

The 6 first recommendations seem logical, the last one let me a bit perplex...

Any technical reason to that?

Best,

Nicolas

Tom had a description that is similar to my understanding as well...

alang.watchprosite.com

it s on the manual and it is a pleasure to fully wind then listen the firs "click"backwards....I usually give it a few "clicks"..just for good measure.Mo

.... a problem to be doing? i don't think so but i am not positive.

...by turning the crown backwards, you are just letting one of the winding gears slip over a clutch.  There is probably some very minor wear associated with this, but in a regularly-maintained watch, it is very unlikely to be a point of failure.  I wouldn't overdo it (i.e., spin the crown while I'm in a boring meeting!), but this is not a common point of premature wear.

After winding for the day, detail-oriented people (like myself?) can also use this backspin as an opportunity to line up the logo on the crown....

Actually you should do this with any watch. Then it becomes a matter of routine.

It is like a reflex now for me with any HW watch.

Just a joke that crossed my mind when I read your post!

You are absolutely correct, all hand-wound watches (including Harry Winston handwound models) should observe the aforementioned rule.

but I think that all these rules should be applied to all high end watches...

(although I am not sure about number seven for the other brands)

cheers

And on some watches, it will benefit the watch. So it's something that is such a small task that there is only a win - win or win - not lose solution.
