Identity design

Sleek and iconic, the design of the STELLAR-X5s Chamonix-Mont-Blanc Edition pays tribute to the peaks. Its white back evokes the purity of eternal snows, the Chamonix-Mont-Blanc logo represents a partnership of excellence, and the "Open the Way" engraving on the edge embodies the shared values of freedom, performance, and durability.

Capture the action wherever you are

Enjoy the best image quality on an Outdoor smartphone thanks to the SONY 50 MP sensor and the 120° wide-angle lens. Capture your moments with stabilized 4K videos, just like an Action Cam, and explore all the available modes. Even underwater, up to 2 meters deep, capture unique shots!

Resistant to all your playgrounds

Designed for all environments, it withstands repeated drops from 1.5 m, meets the military standard MIL-STD-810H, and remains waterproof even in saltwater (IP68). Fully dustproof, it features a Corning Gorilla Glass Victus 2 screen that is resistant to shocks and scratches, and operates perfectly from –20 °C to +60 °C.

As efficient as you are

The STELLAR-X5s Chamonix-Mont-Blanc edition keeps up with your pace everywhere, combining power and smoothness thanks to the Qualcomm Octocore processor, 8 GB of RAM, and 256 GB of storage. Complete connectivity (5G, WiFi 6/6E, eSIM, NFC), long-lasting 4,500 mAh battery, and X-LINK fast charging to stay operational both in the field and at home.

Use with gloves

Thanks to Glove Touch technology, there’s no need to remove your gloves to answer a call, check a map, or take a photo at the summit. Designed for extreme conditions, this feature ensures optimal screen responsiveness, even in severe cold or during intense activity.

Total waterproofing

Certified IP68, it remains completely protected against dust and withstands prolonged immersion, including in saltwater. A rare durability on the market and a hallmark of Crosscall smartphones.
