Swiss watchmaker Rado has been obsessing over highly scratch resistant watches for over 40 years, and now it looks like they have truly outdone themselves with the Rado V10K. The name “V10K” comes from 10,000 Vickers. Vickers are a measurement of hardness and resistance, and 10,000 is the top of the scale — achieved only by diamonds, and now, by the Rado V10K.

Some of the materials that go into the Rado V10K are fairly standard: titanium caseback and clasp (extremely strong and lightweight), sapphire crystal, and a rubber strap (available in black, orange, red, and blue). The rest of the watch, however, is decidedly non-standard. Using a furnace capable of recreating the atmospheric pressure of Jupiter, Rado actually coats the case of the V10K with synthetic diamonds. If diamonds are the hardest substance in the world, the only way to build a truly scratch-proof watch is to actually use diamonds to coat it.
