The Rockshell Mark III Scuba 45 mm is a Swiss Made dive watch designed for performance with character.

Its grey dial brings a restrained, technical tone, contrasted by a blue turning bezel that adds visual energy and function. Clear, legible, and purpose-built, it keeps focus where it matters.

Built for active use, the rotating bezel supports precise timing, reinforcing its professional scuba identity. The case construction emphasizes durability and control in demanding environments.

Paired with a blue rubber strap, the watch offers flexibility and comfort during movement, whether underwater or on land.

A dive watch defined by contrast and capability. Sporty, confident, and engineered to perform.

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

This watch is powered by a Ronda-515-A1C3 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.
