Craftsmanship Breakdown

1. Material Authenticity

   • 904L Oystersteel Case: 40mm×12.5mm dimensions, CNC-machined to replicate the Submariner’s iconic lugs and crown guards.
   • Scratch-Resistant Sapphire: Dual anti-reflective coating for underwater/sunlight legibility.

2. Movement Precision

   • Replicated Caliber 3135 Movement: Engineered to mirror Rolex’s original architecture:
     • Chronergy Escapement: 10% higher efficiency, ±2 sec/day accuracy.
     • Parachrom Hairspring: Anti-magnetic to 15,000 Gauss, shock-resistant to 5,000G.
     • 72-Hour Power Reserve: Bidirectional winding with Rolex-grade rotor silence.
