Hello all,
Perhaps I could shed some light. I had posed this question and received a reply from IWC stating that the Aquatimer 2000 has been engineered to cope with internal over-pressure negating the need for a helium escpae valve. I don't believe there is another dive watch on the market that is designed to handle such internal over-pressures. The only other saturation diver on the market without a helium valve is the Seiko Marinemaster 300. The case is not designed to cope with internal over-pressure, rather the gasket system is designed to not let helium in at all. The Aquatimer, IMO exhibits a level of engineering that no other dive watch does.

Considering the price of an AT2000 I guess it is a pretty good watch. As Shing said...a great performer. The problem with all of the watch ratings is that they are way off on the low end of the scale. And few are around to test the high end.

Please correct me if I am wrong but if the watch stays with the diver, also during decomression, this should provide enough time for the He to leak back out? Maybe the built up He would cause a problem if the watch is submitted to sudden decompression, for example by sending it to the surface in a basket with other stuff that has to be examined on the surface.

Basically.As I understand the physics of the helium escape valve and its function in relation to dive watches being subjected to considerable depths,the valve is there to release the helium gas,thereby to stop the watch from literally exploding,due to the enormous build up of pressure.

Looking forward to your expert opinions on this.
Kind regards,
