The instruction manuals for STERNGLAS watches are available online.
Just select your model and download the matching manual. There you'll find information on how to use your watch, set the time and date, and use special functions such as chronograph or GMT.
If you're not sure which model you have or which manual matches your watch, our customer service will be happy to help.
It's best to have the model name, a photo of your watch or your order number ready.
