CARE AND HANDLING
To ensure that your timepiece functions as perfectly as on the first day, we recommend that you follow a few instructions. Detailed information on setting and handling your watch can be found in the operating instructions. You can also find more information in our FAQ.
WINDING
If you turn the crown back after full winding about one revolution, you relieve the movement and the locking mechanism can click in securely. Keeping the rotor of an automatic watch movement in motion with a watch winder has a positive effect on the lubrication of the bearings and may also eliminate the need to adjust the calendar.
SETTING THE DISPLAYS
Different displays have to be set depending on which model you have chosen. In order to protect the filigree mechanics from unintentional operating errors, protective mechanisms – some of which are even patented – are used in our movements. Nevertheless, please read the operating instructions carefully before setting your watch for the first time. For many models we also offer a video tutorial, which makes the setting even more descriptive.
DATE DISPLAY
If you have not worn your watch with date display for a long time, you must check whether the hands are showing a time before or after 12 noon when resetting the time. To do this, move the hour hand past 12 once and see whether the date changes. If it moves forward, the hour hand is showing midnight. If it does not, the hour hand is showing noon. Now the hands are positioned correctly and you can set the date.
In order to avoid malfunctions, we do not recommend resetting the date display between 10 p.m. and 2 a.m. During this time, various elements of the date mechanism engage with the movement. Sometimes different intervals of time apply for models with calendar function. Detailed information can be found in the operating instructions for your watch.
DAY/NIGHT INDICATOR
If you have not worn your watch with day/night indicator for a long time, please consider checking whether the day/night indicator is showing a time before or after 12 noon when setting the time. If the hands and the day/night indicator are positioned correctly, you can set the date.
GENERAL INFORMATION
WATER
Prior to delivery, your Lange watch is checked for water resistance at a pressure of 3 bar. This ensures that it is protected against splash water and comparable water contact. However, your watch is not designed for bathing or sauna visits.
SHOCKS
Your Lange watch is a delicate mechanical masterpiece and is not indestructible. You should therefore avoid heavy shocks and tremors, for example, when doing manual work or sport.
MAGNETISM
Magnetic fields such as those generated by cell phones, handbag clasps or electronic devices of all kinds will not directly damage your watch but do influence its rate accuracy or even cause it to stop running. If a compass needle moves as soon as your watch – face down – nears the compass, this is a sign that the watch is magnetised. You can have this checked and remedied within the scope of a service intervention.
SCRATCHES
Please note that any contact between your watch and harder objects such as chains and pieces of jewellery you wear on your wrist may lead to scratches on the case, particularly if the case is made of gold.
