The Mares Sirius impresses from the first moment with its high-resolution color display, which uses advanced technology for maximum clarity. The information layout is extremely intuitive, allowing the diver to see all critical data at a glance. The screen protection is entrusted to an exceptionally durable sapphire glass, which offers top protection against scratches, impacts, and intense stress in the demanding marine environment.

At the heart of the Sirius beats the top decompression algorithm Bühlmann ZH-L16C, which fully incorporates customizable Gradient Factors for perfectly tailored safety. It supports the use of up to 5 different gases, including Nitrox and Trimix, making the watch a comprehensive tool for advanced and technical divers. Calculations are performed in real time, ensuring accurate dive profiles and minimizing the risk of decompression sickness.

The Mares Sirius offers the capability of wireless connection with up to 5 cylinder pressure transmitters. This advanced air integration function allows you to monitor the exact pressure of your cylinder, as well as the current gas consumption, directly on your wrist display. The color coding of the screen instantly alerts you to air levels, providing unparalleled comfort and freedom of movement, freeing you from cumbersome high-pressure hoses.

Underwater navigation becomes simple and accurate thanks to the integrated 3D digital compass with full tilt compensation. You can set your course and follow it safely, as the compass remains accurate regardless of the angle at which you hold your hand. The watch also features an expanded digital logbook that stores your dive charts, allowing you to transfer them to your smartphone via Bluetooth for detailed analysis in the Mares app.

The Mares Sirius is made from top-quality materials, combining a sturdy stainless steel bezel with a durable case, offering water resistance up to 150 meters. It comes with a comfortable strap, as well as an extra-long extension strap for use over thick wetsuits. On land, it transforms into a luxurious accessory, featuring fitness tracking, smart notifications for calls and messages, as well as a rechargeable battery with long autonomy.
