It weighs only 2.4 to 3.6 grams, being up to 11 times lighter than a typical smartwatch, while its thickness does not exceed 2.4 mm. Its outer casing is made of aviation-grade titanium, reinforced with a tungsten carbide coating for maximum resistance to everyday scratches. The interior is lined with medical-grade hypoallergenic epoxy resin for absolute comfort around the clock.
