Hoping someone can give me a hand. I am taking delivery of a Datograph Perpetual in the near future, but am unable to find instructions online regarding setting the perpetual calendar. I don’t want to set things in the improper order and risk harming the ... 

... is to contact Lange USA HQ (800-408-8147) to request a manual or at least a PDF of the setting instructions. They might send it to you if nobody here can accommodate, though hopefully someone here who owns one will reach out. Congrats on the watch by ... 

Glad to be here and appreciate the info! Will be sure to post pics when it arrives.

Can try to make a digital copy maybe by taking pics of the key pages on setting for you. It's quite easy not to worry. Will send you soon. And congrats in advance on your upcoming Dato Perpetual. You will love it ! Cheers Robin ...  

I would Greatly appreciate this! What a beautiful picture, can’t wait to receive it soon!

I've taken the liberty of attaching pictures for the perpetual calendar settings here. Hope you find this useful! The quick adjustment via the 10 o'clock pusher is really one of the best features of the Datograph Perpetual. ...

What a masterpiece!

This one simply demands more wrist time. Keep the wrist shots coming!

Totally saved me, very easy too! Haven’t worn anything else for the last week!

The grey dial is simply mesmerizing in the sun, you're a lucky man!
