Few companies have been so consistently identified with the pursuit of excellence, the quest for the absolute, the discovery of original approaches and innovative solutions. Rolex watches have proved themselves from the start in the most extreme conditions imaginable – from the depths of the deepest oceans to the summits of the highest mountains, in the air and on the race track. And to ensure that all Rolex watches can live up to these high expectations, every single one is tested to extremes before it is allowed to leave the Rolex site.
