The Mercury Chrono 43.5 mm draws on the codes of iconic dive-inspired chronographs, reinterpreted through Swiss precision and modern balance.
Its black sunray dial delivers depth and contrast, framed by a tachymeter scale that reinforces the watch’s technical, performance-driven character.
The chronograph layout is clear and purposeful, designed for timing with confidence.
Powered by a Swiss quartz chronograph movement, this timepiece combines reliability with a strong visual identity. The stainless steel bracelet is secured by a butterfly clasp, ensuring a clean, seamless fit on the wrist.
Sporty yet refined, the Mercury Chrono carries the spirit of classic tool watches while remaining composed enough for everyday wear.
A chronograph for those who appreciate heritage inspiration, technical detail, and Swiss-made reliability.
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.
