Where are watches assembled?

We assemble as many of our watches as possible in Germany, but to reduce wait times for our customers, we may use partner workshops in other cities across Asia. Some custom watches may be assembled outside the country due to certain workshops not selling their parts individually.

Are they waterproof?

Our watches have a water resistance of 5 ATM, this mean that they are designed to be water-resistant for everyday situations, such as splashes or rain. However, we do not recommend using them for diving.

I can't find the watch I'm looking for.

Given the thousands of possible combinations, we can't display them all on our website. Please contact us via WhatsApp, TikTok or Mail with the model you're interested in, and we will assemble it as a custom order exclusively for you.
