During extreme diving situations, helium atoms make their way into the watch. As such, the process of decompression could dislodge the watch crystal. The helium release valve prevents this from occurring by allowing the excess pressure to escape via the valve, due to this special valve, it is possible to dive below 300 meters.

Super-LumiNova is a brand name under which strontium aluminate–based non-radioactive and non-toxic photoluminescent or afterglow pigments for illuminating markings on watch dials, hands and bezels, etc. in the dark are marketed. This technology offers up to ten times higher brightness than previous zinc sulfide-based materials. When the luminescent pigments were stimulated by daylight or artificial light, they give off light energy in the dark for several hours. This gives the watch extremely good clarity even in the dark.

A watch like a lion, a sea lion. What animal is closely associated with people and is known for its skillful ability to dive to great depths? The sea lion. The backside of the L2 is adorned with this magnificent creature, whose maneuverability, elegance and function is attuned to life underwater. Represents a diving watch blending all of these traits. Given that the lion is the symbol of Zurich, the city that has shaped the evolution of this watch, it seems only appropriate that the sea lion should be the symbol of the Maurice de Mauriac L2. A roar – both below and above water – has been sent out from Maurice de Mauriac throughout the world.

Sometimes we already get numerous clocks out of the vaults and just let them all start to get in the mood for the wonderful whirring.

Jan Stöckli, our ambassador, and the team management wear our watches. On May 28th, after crossing the finish line, the sponsors who make this team performance possible will be presented with an exclusive watch that we created especially for the Giro d'Italia.
