Register Your Machine

Activate Your Warranty
Please visit this page and click Get Started to enter your serial number. When registering your product, if you receive an error, please try using a lower-case letter as your first character. If you still have an issue, please email customerservice@stundenglass.com with a picture of the authentication sticker on the back of the box and matching serial number etched onto the body. For security purposes, please note that we are not able to register the product for you.
How Can I Tell If My Device Is Authentic?
All authentic Stündenglass unit boxes have a sticker with a scratch-off authentication code on the back of the box, along with the serial number. The same serial number is etched into the body of the unit. These numbers are used to validate and to register your unit at https://stundenglass.com/register. Items lacking these numbers were not produced by us. If the serial number you are trying to enter cannot be registered, you may own a counterfeit unit. Please contact us if you believe this to be incorrect.v
