Comex supplies ROLEX Hyperbaric Chamber for DSSD testing

[Welshwatchman]

Did you know that Comex supplied the hyperbaric chamber that Rolex uses to test every DSSD produced?

The chambr is a highly engineered steel tank which replicates the pressure experienced at 4,875 metres, some 975 metres over the rated capability of the DSSD.

This equates to 4 tons of water pressure on the crystal !

The key technology Rolex have developed to withstand such pressures is of course the Ring Lock System. The ring is made from stainless steel alloyed with nitrogen and is placed between the sapphire crystal and the case back to withstands the incredible pressure generated at such a depth.

The DSSDs are placed into the chamber in batches of ten and subjected to extensive testing for 90 minutes before being pronounced fit for purpose. Here's me thinking that they just stuck them in a Hoover washer dryer for 10 minutes.

Below is a picture of the purpose built chamber. Note the DSSDs in their test trays.
