Specifications on Lundis Bleus watches

What is done by Lundis Bleus, and where do our components come from?


One of the values that is most important to us and that we want to make sure is made very clear is honesty.

Therefore, we have decided to hold absolutely no secrets on the origin of our components and to clearly indicate what we do ourselves and what is outsourced.



The design, engineering, and project management are all done exclusively by Lundis Bleus.


Sales and Customer Service

All the commercial aspects, the management of sales and shipping, the customer service and the overall up-keep of the products are all done exclusively by Lundis-Bleus.



Based on our designs and own technical drawings, our components are manufactured by a dozen of selected suppliers from the vast network we have created in our careers. These manufacturers are based in Switzerland, Europe and Asia (China, Taiwan, Japan and Thailand). All of them have been selected for one main reason: quality! 


The overall quality control of the components on entry, the assembly, the fine tuning of the accuracy, the quality control of the finished products (aesthetic & technique), as well as other operations are all done exclusively by Lundis Bleus in our own workshop.

Our usage of the words “Lundis Bleus” means us, Johan and Bastien, the cofounders. No more and no less.
