The Rado Ceramica Automatic R21807182 is a striking automatic watch with some amazing features. 

First of all, let's talk about sizing. This watch has a nice wrist presence despite having a modest 30mm casediameter. The rectangular design and wide, integrated bracelet give more body to the watch, making it suitable for most mens wrists. The 12.3mm height of the watch, combined with the sleek design, make sure this watch wears comfortably under the cuff of your dress shirt. The watch is powered by a Swiss Made automatic mechanical movement based on the ETA 2671. 

The case and bracelet of the watch are both made of a high-tech ceramic that Rado watches are famous for. This high-tech ceramic material is highly scratch resistant and will ensure the watch keeps looking fresh with every day use. 

Of course the black dial is protected by sapphire crystal, matching the scratch resistant nature of the materials this watch is made of. The whole watch has a stealthy black look, with added interest of the yellow gold coated hands and indices.
