SevenFriday Watch T2/01 Revolution T2/01 Revolution. The SevenFriday watches models T2/01 (Gradient green) and T3/01 (Gradient blue) are carrying the same sun lenses as the new eyewear collection Icon Tiny. The new design language plays with transparency, gradients, a skeleton movement and an effective graphic design, resulting in diving into the interface. The T-Series is smaller, thinner and lighter than other SEVENFRIDAY watch series. Graphic design together with skeleton movement are inspired by the blueprints from the industrial technical department, therefore the use of the letter T.
