History of the collection
The name MN64 comes directly from the date that changed ZRC's history as a dive watch maker: 1964, the year in which the French Marine Nationale (hence the initials "MN") asked the brand to solve a concrete problem on the Grands Fonds 300 then in use, namely the vulnerability of the crown positioned at 3 o'clock during diving operations.
ZRC's answer is the solution that still sets it apart today: the crown moved to 6 o'clock, integrated into a patented protection system, and a monobloc steel case reinforced with molybdenum to resist the magnetic fields encountered during minesweeping. The MN64 was born as a faithful recreation of that watch, reproducing its size, proportions and design details — from the arrow indices to the strongly luminous "Magnum" hands — with the addition of a modern movement and sapphire crystal.
Today the MN64 sits in the ZRC catalogue alongside variants dedicated to specific units, such as the editions made for the fiftieth anniversary of the Mediterranean minesweeping group or for the submarine crews of the Force Océanique Stratégique, confirming the model's role as a direct bridge between the brand's present and its military history.

Main versions
Between 2016 and 2018 ZRC made small series of its Grands Fonds intended directly for French Navy units, including about 50 pieces for the crews of the strategic fleet's submarines: a direct link with the armed forces that few other manufactures can claim.
