The Rockshell Mark III Scuba 45 mm is a Swiss Made dive watch built to make a statement, both in performance and in presence.
Its blue dial delivers strong contrast and instant legibility, designed to support multiple functions at a glance. The turning bezel reinforces its professional dive identity, adding practical control and visual strength.
Engineered for water resistance and active use, this watch embraces a sport-driven character. Robust proportions, functional detailing, and a clear focus on capability define its design.
Paired with a blue rubber strap, it offers flexibility and comfort during movement, whether underwater or on land.
A bold dive watch for those who value function with impact. Technical, expressive, and unmistakably confident.
Built to resist 20 ATM (200m) 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.
