Materials
High-Tech Ceramic Innovative, durable and skin-friendly: introduced by Rado in 1986, high-tech ceramic has become our signature. In metallic or non-metallic colors, with a glossy, matt,satin-brushed or decorated finish, it is the most versatile of our materials.

High-Tech Hard metal
Pure, simple and extremely tough: we pioneered the use of this material by introducing the world’s first scratchproof watch, The Original, in 1962. Sapphire Crystal Perpetual transparency: scratch proof high tech sapphire crystal is used throughout our collection. The application of edge-to-edge crystal and metallization are distinguishing features.

High-Tech Diamond
Incomparable and enduring brilliance: the Rado high-tech diamond surface offers hardness equal to that of natural diamonds. Our invention and use of this surface have earned us an entry in the Guinness Book of Records for the world’s hardest watch.

How hard is hard?
The extreme hardness of Rado high tech materials guarantees durability and brilliance. The Vickers scale is used to indicate hardness: the higher a value, the greater the resistance to scratches. Rado materials commence at Vickers 1,200 – far higher than gold, steel or platinum. The top value of 10,000 is attributed only to natural diamonds and to the Rado high-tech diamond surface.

Rado quartz watches are equipped with top-quality Swiss batteries. Under normal conditions, a battery should last at least 30 months. The battery must be changed when the seconds hand starts to move in 4-second intervals (or when, on a multifunction watch, the digital display begins to blink). Battery exhaustion in a watch without a seconds hand becomes apparent only when the hands stop moving altogether. Battery changes should only be performed by an authorized Rado dealer or Service Center to ensure that only original parts are used and that your watch is properly tested for water resistance. A worn-out battery should be replaced immediately in order to reduce the risk of leakage and consequent damage to the movement.
