Our Service

Each vintage watch is individually selected and carefully checked by us. After we purchase a watch, it is mechanically and fully tested and inspected in our watchmaker's workshop. If necessary, the movement will be fully serviced to ensure it meets our high standards.

We will always describe the watch as completely as possible in our sales texts. Our zoomable images are of the highest quality and form an important part of the description of each watch. Therefore, we do not retouch our images. We will never hide or cover up any element of a watch we sell.

One element of our unparalleled service is fully insured courier shipping with personal delivery. Once you receive your watch, we encourage you to inspect it thoroughly. If you are not 100% satisfied, please let us know. We offer a 14-day return policy. Simply return the watch for a full refund.

Our Warranty

We offer a one-year warranty on the mechanical function of the watch from the day of purchase. We do not guarantee the water resistance of (vintage) watches unless expressly stated in writing.
