The Helios Power 43.5 mm marks a new chapter in Swiss watchmaking, where innovation meets independence.
Powered by light, its solar movement transforms energy into precision, removing the need for battery changes while ensuring reliable performance every day.
Time advances continuously, driven by a source as constant as daylight itself.
The gunmetal tone bracelet and dial reinforce a technical, contemporary character, balancing strength with restraint. Clean lines and purposeful design reflect a watch built for modern life.
Developed by Roamer, this timepiece embodies progress without compromise. Efficient, durable, and forward-thinking, it redefines what a Swiss chronograph can be.
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.
