Craftsmanship Details

1. Monobloc Case Construction

   • Forged from single-block 904L steel with CNC-machined lugs (42° taper angle). Screw-down caseback and crown ensure 100m water resistance.
   • Sapphire crystal with dual anti-reflective coating (92% light transmission), glare-free under direct sunlight.

2. Movement Performance

   • Instant day/date module: English day display at 12 o’clock with authentic mechanical feedback during jumps.
   • Anti-interference design: Nickel-phosphorus escape wheel + Paraflex shock absorbers resist 15,000 Gauss magnetism and 5,000G impacts.

3. Bracelet Ergonomics

   • President bracelet links weigh ≤0.03g each, with brushed interiors to prevent skin irritation. Lug tolerance ≤0.1mm.
   • Concealed folding clasp tuned to 0.8N·m damping force, replicating the original’s "Click" tactile response.

Design Authentication

• Rehaut Engraving: Laser-etched "ROLEX ROLEX" aligns with the 12 o’clock coronet (deviation ≤0.2mm).
• Certification Text: Dial inscriptions "SUPERLATIVE CHRONOMETER" and "OFFICIALLY CERTIFIED" replicate Rolex’s silk-screen printing technique.
• Caseback Detailing: Screw-down caseback engraved with unique serial number (e.g., X0A123, 0.15mm depth).

Usage Scenarios

• Boardroom Authority: Black-gold palette exudes executive power, commanding attention during negotiations.
• Evening Galas: Bracelet’s light refraction and subtle lume (faint blue glow on hands) elevate black-tie ensembles.
• Daily Resilience: 904L steel resists sweat, rain, and scratches—wipe clean with a microfiber cloth.
