What is the difference between a manual winding and an automatic mechanical movement?
The difference between these two types of mechanical watches lies in the winding method. Manual winding watches need to be wound by hand every day using the crown. Automatic watches can be wound this way too, but also have an internal rotor that provides energy by reacting to the wrist's movements - hence "automatic".
How often must/should I wind a mechanical watch?
It depends on the watch's mechanism. Manual winding watches are wound daily using the crown, ideally always at the same time. Their tension spring, also called the mainspring, is fastened to the spring barrel. When the crown cannot be turned any further, the watch is fully wound.
An automatic watch which has not been worn for a while must also be initially wound manually using the crown. Around 30-40 turns are needed, depending on the calibre. Once the mainspring of an automatic watch is fully wound, the tension spring's slip clutch takes effect, preventing the watch from being "overtightened".
What power reserve does a Glashütte Original automatic watch have?
The power reserve in a Glashütte Original automatic watch depends on the mechanism type and the movements of the owner. Fully wound, the power reserve of the watch is between 40 and 100 hours, depending on the model. Information on your watch's power reserve can be found in the accompanying user manual (operating instructions) or in the model overview on this website.
What level of rate precision can I expect from a Glashütte Original?
The rate precision of a mechanical watch can vary depending on mechanism and wearing habits.
Glashütte Original watches are adjusted within the following tolerance ranges:
Manual winding: -4 to +6 seconds in 24 hours (average daily rate)
Automatic winding: -5 to +10 seconds in 24 hours (average daily rate)

If you notice the rates of your Glashütte Original outside these tolerance ranges over a longer period of time, please contact our service staff.
Do I need a watch winder?
Watch winders are particularly advisable for collectors and connoisseurs who own several premium timepieces and/or do not regularly wear their watch(es).
Watch winders keep the mechanism constantly moving, allowing calendar functions to continue, and avoiding the need to reset hands, particularly for perpetual calendars. The "viscosity" of the oils inside the mechanism - their suppleness - also remains constant over an extended period.
Watch winders are incidentally not suitable for hand-wound watches and do not replace an actual inspection.
How should my watch winder be set?
To ensure optimum winding, we recommend setting a watch winder to approx. 800 - 1,000 rotations per day.
Please note the following recommendations for rotation direction:
Calibre 100 - both sides
Calibre 95/96 - both sides
Calibre 90 - counterclockwise
Calibre 39 - counterclockwise
Calibre 37 - both sides
Calibre 36 - both sides
