The Helios Power 43.5 mm embodies a new vision of Swiss watchmaking, where light becomes power.
Its black sunray dial absorbs and transforms light into energy, driving a solar chronograph movement designed for long-term reliability.
Precision continues without interruption, powered by daylight and motion.
The gunmetal tone bracelet and case reinforce a modern, technical character. Purposeful lines and balanced proportions give the watch a confident presence, suited to an active, forward-looking lifestyle.
Built for those who value independence and innovation, this timepiece redefines performance through intelligent design. Efficient, resilient, and unmistakably modern.
Built to resist 10 ATM (100m) water resistant
Every watch is tested to Swiss NIHS 92-20 standards — the gold benchmark for water resistance. Rain, splash, or spontaneous swim? You’re covered.
From scratch resistance to salt spray, every detail meets NIHS 96-22 standards — because beauty shouldn’t fade.
Antimagnetic Protection
Protected against magnetic fields up to 4,800 A/m (NIHS 90-10), so your watch stays accurate — even near electronics, bags, or airport trays.
Shock Resistance
Drop-tested and impact-simulated (NIHS 91-10 & 91-20), your timepiece is built to handle real life — not just glass cases.
Luminosity
Certified photoluminescent coatings (NIHS 97-21) make sure your watch shines bright when the lights go down.
Movement Accuracy
This watch is powered by a Ronda-2030.D-A1C4 caliber, engineered to meet the NIHS 95-11 standard.
Skin Compatibility
All parts are certified skin-safe and climate-resistant (NIHS 96-50), so your watch feels as good as it looks.
