LUNETTE
ECS™ PATENT (Easy Clean System)
The ECS™ is a technical solution to the problems experienced by the divers of the National Navy during their multiple dives: the salt crystallized in the spaces between the bezel and the box, thus blocking its rotation. For the 2015 edition of the Great Fund 300, ZRC has developed and patented a functional solution. The™ ECS was born. A unique system of cleaning the interior of the telescope by a clear water flow allowing the dilution and disposal of sea salt, the ECS™ is the ultimate tribute to the Great Fund of origin and is clearly part of the DNA of the brand.
CROWN
Crown Protection System™
100 % guaranteed safety thanks to the exclusive system of escamotable handles. The release of the water without having revisited the crown in the initial position is impossible. Not crayfish, it prevents the bracelet from recovering in place. An effective method for dealing with the forgetts that cause technical inconvenience.
BRACELET
The diver bracelet
The new 300 Grand Fund is equipped with an automatic adjustable bracelet that allows it to be worn over the diving suit. This unique system of spring drowned in the mass adapts automatically to the diameter of the wrist and allows the comfort of unbeatable wearing. No adjustment, the two straws on both sides of the box extend to adapt to the new diameter.
