RC continues its journey with a modern reinterpretation of the iconic Grands Fonds S1. "La vie est Aventures”, it is also about getting off the beaten path.

A challenge pushes you to go beyond your limits, to explore unknown territory – the realm of audacity. What began as a challenge turned into an unforgettable story. ZRC’s story began in 1958 when the French Navy issued a call for tenders for the production of deep-sea diving watches. This information was passed on to Louis Brunet, CEO of ZRC. At that time, the brand was, among other things, specialised in the manufacture of water-resistant cases.

Quickly, the excitement spread through ZRC’s workshops. A study launched for the Annecy Lake firefighter divers helped to strengthen the presentation to the Navy. The final prototype of the S1, equipped with a Felsa 4000, was presented in 1959. Tested for nearly 6 months, the S1 was finally approved by the Navy, giving birth to the first ZRC watch.

The S1 stands out with an attractive presentation of time information on its dial, where the “guilloché” indexes feature an elegant, slender leaf shape enhanced by its classic diver’s bezel. The airy design provides precise time reading.

In 1965, the Securicode made waves as the very first diving watch capable of providing advanced immersion times at various depths. It retained the effective aesthetics of the S1, and the name Securicode became iconic after winning 1st prize at the 11th Inventors’ Exhibition in Brussels.

In 2024, ZRC reconnects with its bold design and celebrates the jubilee of the S1 with a collection bearing the emblematic Securicode name.

All Securicode models feature the S1’s historic Magnum-type hands and a lollipop second hand, adorned with beige or green Super-LumiNova depending on the version. Their black dials in solid “guilloché” brass are topped with a blue anti-reflective sapphire crystal, which take on marine hues in the sunlight. This evocation of oceanic colour makes it easy to read in all conditions.

For uncompromising versatility and to be worn on both men’s and women’s wrists, all Securicode watches combine their vintage personality with certified water-resistance to a depth of 300 metres (30 bars), thanks to a 39 mm case combined with the brand’s renowned programmed deformation caseback.

With the Securicode Diver 300, ZRC marks the grand return of its very first diving watch.

Securicode Diver 300 Steel:

Its double-thickness “guilloché” brass dial integrates a stainless steel case with a bezel and insert machined from the same material. The whole has a circular brushed finish, just like the original models. This contemporary reinterpretation is accompanied by a resolutely retro-chic expansion band bearing ZRC signature. The hands are powered by a high-performance SW200-1 automatic movement in its elaborated version.

Securicode Diver 300 Steel/Ceramic with date:

The Securicode family also expands with a model combining a stainless steel case with a bezel featuring a scratch-resistant ceramic insert. A distinctive feature of this model is the date positioned at 3 o’clock on the dial. A Tropic rubber strap inspired by those made in the 70’s, reinforces its sporty chic personality.

Securicode Diver 300 Limited Edition Bronze/Ceramic with date:

ZRC celebrates its new collection with a limited edition featuring a forged bronze case. The watch takes up the features of the Securicode Diver 300 Steel/Ceramic with date. The hands and hour-markers are finished in Super-LumiNova eggshell to match the colour of the case. For a perfect look, this edition is worn on a vintage leather strap.

All Securicodecome with a cap specially developed for the occasion, and are beautifully presented in a gift bag featuring vintage advertising.
