Why not using a helium release valve you may ask as the Borealis Sea Hawk is built with specs to be used for saturation deep diving.

The answer lies in the case back. By using screws to secure case back the watch works as a compressor case where the increased pressure of water makes it more and more water resistant.

In a decompression chamber used in saturation diving the pressure of atmosphere starts to decrease and with it the case back secured with screws accommodates the pressure differential making it possible for helium trapped inside watch to escape to atmosphere without compromising water resistance.

This is an elegant and ingenious solution for building watches for saturation diving.
