As the name states, the dial of the watch is coated with a layer of ruthenium giving the watch a beautiful hue resembling slate. Depending on the light, the dial varies from a very dark charcoal grey to an occasional silver-like reflection thanks to the domed crystal. At 12, a forty-eight hour power reserve allows the wearer to ensure the watch is always properly wound. At 6, the one-second remontoir d’égalité is visible. At 9 and 3 respectively, the tourbillon and guilloché dial.
The hand-wound movement of the Ruthenium T is the caliber 1498, made from brass, the movement is also coated in ruthenium covering the côtes de Genève finishing. These brass movements are very few in numbers due to their short production from 2001 to 2004. Obviously, this makes them adored by collectors for their rarity.
