Cartier 21 Must de Cartier

On Hold

In the last few years, Cartier has exploded in popularity to become one of the most sought after brands in both the vintage and modern sectors.

Known as the Master of Shapes, Cartier is well-known for its funky case design and timeless elegance. The Must de Cartier watches are now equally sought after and represent great value for Cartier fans.

This is a quartz powered 31mm steel watch with integrated-bracelet look and cool bezel with gold filled Roman numerals. The dial has an eggshell hue and classic blued hands with matching blue cabochon topped setting crown.
The steel case with gold accents and two-tone bracelet give this watch a cool look. The watch will fit a wrist size up to 17.5cm. The watch has been checked by our watchmaker and a new battery fitted.

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.
