Business Closing USA – A Message from Our Founder
To our friends and customers in the United States,
This is Dustin, founder of Sternglas.
Writing this message feels heavier than usual. For years, it’s been a joy and an honor to send our timepieces from Hamburg to the United States. Knowing that our watches were worn across the ocean by people who share our love for design and craftsmanship has meant more to me than I can say.
But now, something is changing.
Due to new regulations, we may no longer be able to ship to the US after August 28. We’re doing everything we can behind the scenes, but I need to be honest with you – there’s a real chance this is goodbye, at least for a while.
If you’ve been thinking about adding a Sternglas to your collection, this is the moment.
👉 Use code CLOSING15 to receive 15% off your order, valid through August 26, 11:59 PM EST.
All packages will be shipped duty-free with no tariffs, delivered directly to your doorstep via DHL Express.
And don’t worry: your warranty remains fully valid.
Even if we can’t ship to the US for a while, your 2-year international warranty is still covered, and our service team will continue to support you.
I don’t want to see this connection between us break. Your support has shaped Sternglas into what it is today. Every order, every message, every photo of your watch on your wrist – it’s all been part of something truly special. And if this really is our last shipment for now, I want to make sure you don’t miss out.
Thank you for being part of this journey. Thank you for believing in us.
I truly hope this is not the end – only a pause.
With gratitude,
Dustin
Founder, Sternglas
P.S. Please don’t wait. After August 26, I can't guarantee we’ll be able to reach you in the US anymore.

Naos Automatik Blue Orange: Maritime Charm Meets Timeless Elegance
Worry-free thanks to sapphire crystal
We only use sapphire crystal for our timepieces. This type of watch glass is usually found in the luxury watch market.
For a perfect view of the dial, we apply a double anti-reflective coating to the sapphire crystal.
What exactly is sapphire crystal?
What exactly is sapphire crystal?
Sapphire is the third hardest transparent material in the world - after diamond and moissanite.
Curved sapphire crystal not only looks good, it makes the durable watch crystal even more resistant.
This makes it virtually impossible for your sapphire crystal watch to get scratched in everyday life.
Maritime Flair for Your Wrist
Award-Winning Design, Precise Engineering
Why we make Bauhaus watches?
In your search for a classic and durable watch, you are faced with 2 alternatives today:
1. you can buy a watch from a luxury manufacturer for a very high price, or
2. a watch from a trendy brand whose quality is as short-lived as the trend that made the brand popular.
Moin! I'm Dustin Fontaine, Founder of STERNGLAS...

When I worked in a watch manufactory during my school days and was looking for a watch for myself, I realised that there would have to be a 3rd alternative.
3. Since 2016, we have been breaking new ground and developing timeless Bauhaus-style watches that will outlive trends and continue to give pleasure for many years to come. And all that at a fair price.
In the meantime, over 53,000 watch lovers are convinced of our mission and our watch design has received several awards.
