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

With COSC-level accuracy (–4/+6 sec/day, NIHS 95-11), every second counts — and lands where it should.

Skin Compatibility

All parts are certified skin-safe and climate-resistant (NIHS 96-50), so your watch feels as good as it looks.
