Price on request

White gold steps to deep pool of black…

The Ellispe D’Or reference 3634 is a large size Ellipse measuring 38x33.5mm and features a very unusual three-step case.

These watches were sometimes fitted with rare hardstone dials, such as this incredible example with an onxy dial. The dial is clean with no hour markers and very clean white gold coloured no-lume hands. The watch is powered by the legendary automatic calibre 28.255, the same movement as the 3700 Nautilus. This Ellipse comes on the pictured leather strap that is fitted with the original Patek Phillipe white gold buckle.
The watch is accompanied by an extract stating the watch was made in 1975, as well mention the onyx dial . The movement has been fully checked and regulated by our watchmaker.

Our Service

Each vintage timepiece is individually selected and carefully inspected by our team of experts. After we buy a watch it is mechanically inspected and fully checked by our watchmaker. If necessary, the movement will be fully serviced and tested to ensure it is running to our exacting standards.

We will always describe the watch as fully as we can in our sales texts. Our zoomable images are of the highest possible quality and form an important part of each watch’s description. We will never hide or cover up any element of any watch we sell.

Key to our unparalleled service is Fedex Priority shipping, fully insured. Once you have received your watch, we encourage you to inspect it thoroughly. If you are not 100% satisfied, please let us know. We offer a 14 days return policy. Simply return the watch to get a full refund of the original purchase price.

Our Warranty

We offer a one-year warranty on the mechanical function of the watch, starting from the day of purchase. We do not guarantee the waterproof nature of any (vintage) watch, unless expressly made in writing. Therefore, our warranty will not cover any damage done to the case and/or movement by water or moisture entering the watch. Our warranty does not apply to accidental damage or mishandling of your watch and does not extend to the bracelet, case parts (including pushers, winding stem, crown and bezel), watch glass, dial and hands.
