Diving Watches
C-02 Nereus
C-02 HERITAGE
C-02 TACTIK
ULTIMATE
Inspired by our projects with the military, the C-02 collections bring together the essential expertise developed for diving, in versions designed for the general public. Thinner, more robust, and more readable than their predecessors, they are ready to accompany you on your next escapades!

Ready for the abyss
The K-02 is our very first model dedicated to diving, launched in 2016. It marked the beginning of the adventure by descending to -267 m during a French record with caver Frédéric Swierczynski. Since then, we've learned a lot in the field. We've collaborated with mine clearance divers, customs divers, marine commandos, submariners, clubs... In short, professionals who know exactly what they expect from a robust and reliable diving watch.
The C-02 is a bit like a distillation of all this accumulated know-how. It incorporates the essential improvements we've developed over the years, with three versions to adapt to specific needs:
• C-02 Heritage : a classic design with a “limited edition” French movement
• C-02 Tactik : designed for action, with enhanced readability
• C-02 Nérée : more compact, with a versatile look for everyday use


Trust Mechanics
FRENCH & SWISS MOVEMENTOver time, we've refined our settings. Some of our watches have passed through the Besançon Observatory, which has allowed us to raise our standards – because the famous Viper hallmark isn't obtained by chance. Today, we apply the same protocols to all our three-hand movements: adjustment to 6 positions, with an accuracy of between –4 and +6 seconds per day.
In the C-02, we find two reliable calibers, chosen according to the version:
• Sellita SW200 (Swiss Made)
• France Ébauches : a French movement used on the Heritage version

ULTRA TECHNICAL
The C-02 is a field watch, designed to remain legible and reliable in all conditions. The hands, indexes, bezel, and dial have been redesigned for maximum underwater visibility, with enhanced contrast and well-adjusted proportions. To ensure easy reading even in low light, high-performance Swiss Super-LumiNova, specifically BGW9, is used, applied in thick layers.
Technically, it looks like this:
• 316L steel case , robust and corrosion resistant
• Sapphire crystal with triple anti-reflective treatment
• Unidirectional 120-click bezel , ceramic or sapphire
• 3D index in Super-LumiNova , up to 16 layers on the Tactik version
• Bracelet with adjustable folding clasp , compatible with wetsuit

IN FRANCE
The C-02s are assembled in our workshop in Nantes by our watchmakers. The workshop is perfectly equipped to carry out all stages on-site. Each watch is assembled to order, which allows us to remain flexible and organized.
We take care of everything internally:
• Design, assembly and adjustment carried out in-house
• Rigorous control : water resistance, chronocomparator, manual checks
• Delivery within 15 working days , excluding pre-orders
