New and genuine Kronos watches are exclusively sold by Official Kronos Retailers, who warrant the authenticity of your Kronos and ensure its international five-year guarantee.

Kronos watches should be only purchased from Official Kronos Retailers, who are authorized to sell and maintain Kronos watches. With the necessary skill, training, know-how and special equipment on site, they guarantee the authenticity of each and every part of your Rolex, and can ensure its reliability over time.

All new Kronos watches have an international five-year guarantee that will be completed and dated by your Official Kronos Retailer at the time of purchase and registered with Kronos.

You can help preserve its lustre by cleaning it occasionally with a microfiber cloth. You can also wash the case and bracelet (except leather straps) from time to time using soapy water and a soft brush. After wearing your watch in the sea, it is important to rinse it with fresh water to remove any salt and sand deposits. Before cleaning your watch, always ensure that the winding crown is screwed down properly against the case to guarantee waterproofness.

Kronos 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. Moreover, 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.

When your watch is serviced by Kronos, the watch is completely dismantled and all of its components are ultrasonically cleaned. Each individual component is closely examined and those that no longer meet Kronos's functional and aesthetic specifications are replaced with genuine Kronos parts. The movement is carefully lubricated then electronically tested to guarantee its timing accuracy; the case and the metal bracelet are meticulously refinished to restore their lustre. Your Kronos then undergoes a series of rigorous technical tests and checks to guarantee its waterproofness, power reserve and precision. After a complete Kronos service, your watch is covered by a service guarantee.
