Spirit OF Big Bang MECA-10 King Gold 45MM

REGAL 18K KING GOLD CHASSIS IN A COMMANDING MASCULINE TONNEAU PROFILE

This exceptional timepiece projects absolute dominance through its signature 45mm barrel-shaped (Tonneau) multi-layered sandwich case, beautifully sculpted from Hublot’s exclusive 18K King Gold alloy. Developed with platinum to achieve a significantly warmer and richer tone than traditional 5N gold, the King Gold structure features a beautiful alternating interplay of satin-brushed surfaces and highly polished beveled facets, radiating a sophisticated and deeply luxurious metallic shine.

The structural stance is enriched by a technical bezel that undergoes an alternating treatment of satin-finishing, polishing, and microblasting, secured firmly by 6 iconic H-shaped titanium screws. Beyond its opulent aesthetics, this heavy gold framework guarantees superior daily durability and resistance to corrosion. Fitted with an integrated black structured lined rubber strap and an 18K King Gold and black-plated titanium deployment buckle, the robust framework ensures an impressive and secure 100m water resistance (10 ATM).

MATTE BLACK SKELETON PORT INTERFACE AND THE ANTHOLOGY OF KINETIC MECCANO MECHANICS

The visual soul of this creation is beautifully laid bare through its industrial matte black skeleton dial. This open-worked architecture allows the collector to observe the intricate micro-mechanics of the manufacture movement, inspired by the structural geometry of vintage Meccano construction sets. The technical layout is engineered to keep the calculations perfectly clean and highly scannable: featuring a linear sliding rack pinion system that shifts along the top perimeter during manual winding, a distinct numerical date-style disc showing the exact remaining days of power reserve at 6 o’clock, and a critical red warning dot at 3 o’clock that activates when energy is low. The applied indices and bold hands stand out in sharp relief against the darkened gears, generously treated with premium luminescent material to guarantee legibility under any lighting condition.

MANUFACTURE CALIBRE HUB1233: IN-HOUSE HAND-WOUND ENGINE WITH AN UNPARALLELED 10-DAY POWER RESERVE

Ensuring absolute operational precision and authority is the mechanical manual-winding Calibre HUB1233 Manufacture skeleton movement, designed, engineered, and built entirely within Hublot’s workshop in Nyon. Utilizing an advanced architecture powered by twin coupled mainspring barrels operating in tandem with specialized driving gears, this mechanism achieves a monumental power reserve of approximately 240 hours (10 full days) on a single winding routine. With every gear wheel, bridge, and mainplate meticulously open-worked and blackened to create an exquisite industrial canvas, this hand-wound masterpiece stands as a legendary hallmark of avant-garde horological technology curated for the selective elite collector.
