Why do 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! My name is Dustin Fontaine,
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.

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.
