Helium escape valve

Your OMEGA Seamaster Professional Diver is the watch for professional and amateur divers, as well as demanding sportsmen and –women. A robust design, the new helium escape valve (exclusive OMEGA patent), together with all the protection systems, offer optimal security and reliability. In order to ensure that your watch remains watertight, we recommend that you have it checked by an authorised OMEGA partner every year.

pressure is gradually increased to

reach the pressure at the working depth. The divers, still inside the bell, are then lowered to the working site. They leave the bell to carry out their work.

Once their work is complete, they re-enter the bell, which is then raised to the surface. Pressure is then returned to atmospheric levels and this is when the valve must be opened (only for deepsea dives lasting several days).

The helium molecules diffuse and penetrate the material of the gaskets. The quantity is sufficient to push out the crystal during the return to atmospheric pressure. To avoid this, the Seamaster Professional Diver is equipped with a valve specially developed by OMEGA.

The Omega SA 1424 is particularly notable for its bold design and robust construction. It is often viewed as a new generation of dive watches, equipped with luminous markers for visibility in low-light conditions. The water resistance of the 1424 ensures it can withstand the rigors of underwater exploration, making it an ideal companion for adventure enthusiasts.

Lastly, the Omega SA 2520 model stands out with its sophisticated chronograph function. This timepiece is optimized for precision timing with additional features such as a tachymetric scale, allowing users to measure speed over distances. The 2520 boasts a dynamic design, often adorned with a striking bezel and a combination of polished and brushed finishes, ensuring it remains a statement piece on any wrist.
