The True Thinline LTA Tennis Exclusive is the thinnest ceramic watch that Rado has ever produced, with the cases of the quartz models measuring a mere 4.9 millimeters. Hailed as a marvel of engineering when it was first unveiled in 2011, the Rado True Thinline’s elegant simplicity is powered by an unbelievably thin movement of just 1mm. Though they may look delicate, this unisex Rado True Thinline timepiece still boasts the same durability and scratch resistance as Rado’s other high-tech ceramic models.
