To ascertain that Rolex Oyster cases have retained their original resistance to moisture and can be guaranteed to withstand pressures equal to 50 meters or 165 feet in regular Oyster cases and 200 meters or 660 feet in Submariner cases, they should be tasted in the Rolex “vacuum tank”.
If it is necessary to make repairs please be guided by the following simple instructions:
Order all necessary parts from your local material house or directly for Rolex by indicating the four digit case reference number located between the case lugs at the 12 o’clock side of the case.
Replacement of Crystals
When removing the case bezel for the purpose of replacing the crystal, it is sometimes necessary to start by forcing a razor blade between the bezel and the case to make a space sufficiently wide for a knife blade.
The crystal should be removed in the same careful manner, taking care not to scratch the case wall where the crystal fits. A scratch in this area could cause a leak.
