Hublot Big Bang Unico Full Magic Gold 42 mm — a bold fusion of scratch-resistant 18K “Magic Gold,” skeletonized chronograph engineering, and a sleek black rubber strap; where luxury meets Hublot’s signature high-tech chronograph design.
Key Features
• Case & Bezel: Polished 18K Magic Gold alloy — scratch-resistant gold / ceramic fusion.
• Bezel Screws & Accents: Six H-shaped screws in black-plated titanium, plus black pushers/guards for contrast.
• Crystal: Sapphire crystal (front, and sapphire + exhibition case-back) with anti-reflective treatment.
• Water Resistance: 100 meters / 10 ATM.
• Strap: Black structured rubber strap, with structured lined rubber and deployant (folding) clasp in black ceramic and black-plated titanium.
• Limited Edition: The 42 mm Full Magic Gold version is produced in limited numbers (c. 200 pieces) — adding to its exclusivity.
Dial
• Style: Matte black skeleton (open-worked) dial — exposing elements of the movement beneath.
• Markers & Hands: Baton-type indices and skeletonized hands, treated with luminescent material (Super-LumiNova) for legibility; markers, sub-dial rings and hands finished in satin/microblasted 3N gold to match the Magic Gold case.
• Chronograph Layout: Two-register chronograph: 60-minute counter at 3 o’clock, running-seconds sub-dial at 9 o’clock. Date window incorporated on or near the chronograph register (depending on version).
• Design Feel: Industrial and architectural — skeleton dial + gold accents + black-on-gold contrast gives a modern, technical look.
Movement
• Movement: In-house HUB1280 UNICO self-winding chronograph (flyback, column-wheel) calibre.
• Components: ~ 354 components, with ~43 jewels (some sources reference 43; others note the revised UNICO-2 with 354 parts) depending on batch.
• Frequency: 28,800 vph (4 Hz).
• Power Reserve: Approx. 72 hours when fully wound.

Warranty
• As per standard practice for new pieces from the manufacturer and authorised dealers, the watch is normally sold with a manufacturer’s warranty (usually 2 years for new Hublot retail). (E.g., a retailer listing shows a 2-year warranty.)
• Service / after-sales care should ideally be done by authorised service centres to maintain the integrity of the Magic Gold case and the UNICO movement.
Weight
• Hublot does not publicly publish an official “gram weight” for the Magic Gold 42 mm version.
• Given the materials — solid 18 K Magic Gold case, ceramic/titanium accents, and a robust automatic chronograph movement — the watch likely carries a substantial, but wearable presence on the wrist.
• The structured rubber strap and deployant clasp help balance the watch for comfort despite the density of the materials.
