Design & Craftsmanship

Maritime Heritage & High-Visibility Orange

In professional diving history, orange dials are renowned for their high contrast against oceanic backgrounds and diving suit gear. In this 44.00 mm execution, the bold orange dial face commands immediate attention while providing clean, legible spacing for oversized luminous indices and hands. The brushed 316L stainless steel case features protective crown guards designed to prevent accidental impacts against boat decks or coral reefs.

Tactical 44mm Stainless Steel Architecture

Forged from surgical-grade 316L stainless steel, the case combines satin-brushed flanks with polished bevels. The unidirectional rotating bezel features deep knurling along its edge, allowing divers to adjust and track dive times with positive clicks even while wearing thick neoprene diving gloves.

Powermatic 80 Engine with Nivachron™ Resilience

Beneath the dial beats the Swiss-made Powermatic 80 automatic calibre. Delivering up to 80 hours of power autonomy, the watch remains running and accurate throughout a long weekend off the wrist. Its patented Nivachron™ balance spring provides critical protection against magnetic fields emitted by boat motors, navigation equipment, and modern personal electronics.
