The Rolex Oyster “Perpetual” is the most accurate series-produced wrist chronometer that winds itself automatically.

It offers unprecedented convenience. You wear it on your wrist; after winding it by the crown and setting it to the second just like any other watch, you don’t have to worry about it any more. The slightest movement, the slightest change of position of the arm will activate the patented rotor which turns in both directions, silently, without any shock, without any vibration. It is enough to wear it on the wrist for a few hours to wind it completely, so that the watch continues to run through the night, on the table, with the utmost precision.

It also offers unprecedented precision. The perfect running smoothness is a technical phenomenon resulting from the constant spring tension and a truly superior quality of workmanship.

The Rolex Oyster-Perpetual chronometer is regularly accompanied by its official running bulletin.

It is characterised by its permanent water-resistance. Enclosed in the “Oyster” case, the most permanently water-resistant case in existence, and thus protected against external influences such as water, sweat, sand, snow, etc., this is the ideal chronometer. Each Rolex-Oyster watch has been subjected to a pressure of 6 atmospheres.
