Materials & Build
We use a dense, vulcanized rubber that resists UV rays and skin oils. The convex notch is precision cut to match the specific lug geometry of the Cartier Blue Balloon series. Unlike standard straps, this design fills the gap between the watch case and the band for a seamless look. The material is sweat-proof, rinse-clean, and shower-safe, making it a functional alternative to leather or metal. Each strap features a brushed buckle that resists scratches and maintains its finish over time.

It accommodates wrist circumferences between 155mm and 210mm. The notched end is specifically engineered to fit the rounded case of the Blue Balloon, ensuring the strap does not rotate or gap at the connection point.

FAQ
Can I swim with this strap?
Yes, the rubber material is completely waterproof and shower-safe. It does not absorb moisture like leather or fabric, so it will not develop odors after getting wet. We recommend rinsing it with fresh water after swimming in salt water or pools to maintain the finish.
Does it include spring bars for installation?
Yes, we include the necessary hardware to ensure you can mount the strap immediately upon arrival. The convex design snaps into place once the spring bars are seated, providing a factory-style fit that looks like it came with the watch.
How do I clean the rubber?
Use a drop of mild dish soap and warm water. Gently scrub the surface with your fingers or a soft cloth to remove skin oils and dust. This keeps the rubber looking new and prevents the material from becoming brittle over several years of use.
Will it fit other Cartier models like the Santos?
This strap is specifically notched for the Ballon Bleu case. Because the Santos and Tank models use different lug shapes and attachment systems, this convex strap will not fit those models. It is designed exclusively for the rounded Blue Balloon case architecture.
Is the buckle removable?
Yes, the buckle uses a standard screw or pin system. This allows you to swap the included hardware if you have a preferred buckle from your original strap, provided the widths match at the buckle end.
If you need help with the installation, check our watch band replacement guide. You can also learn how to replace a watch buckle if you want to use your original hardware with this new rubber strap.
