Hublot Big Bang Complications MP-11 Power Reserve 14 Days Magic Gold Limited Edition 45mm Magic Gold Skeleton Sapphire Dial Rubber Strap 911.MX.0138.RX - BRAND NEW

The Hublot Big Bang MP-11 reference 911.MX.0138.RX stands as one of the most technically ambitious and visually dramatic watches in Hublot's entire catalog. Part of the brand's MP — or Manufacture Pieces — collection, the MP-11 was conceived to showcase complications and engineering achievements that push well beyond conventional watchmaking. This particular limited-edition example in Magic Gold with a skeleton sapphire dial represents a rare convergence of exotic materials and horological substance, and it arrives at Bizak & Co. in brand-new condition, complete and unworn.

Magic Gold is a material exclusive to Hublot and one that transformed the luxury watch industry when it was introduced. Developed in partnership with the École Polytechnique Fédérale de Lausanne, Magic Gold is a 18-karat gold alloy that is virtually scratch-resistant — a property virtually unheard of in precious metals. Hublot achieves this by infiltrating a boron carbide ceramic lattice with liquid gold under high pressure, creating an alloy with a Vickers hardness far exceeding that of standard gold. On the 911.MX.0138.RX, this material clothes the full 45mm case and the bezel, giving the watch the warm luster of fine gold with the durability of a tool watch.

The dial — if it can even be called that — is an exercise in openworked transparency. A sapphire plate replaces any traditional dial surface, allowing an unobstructed view of the movement architecture beneath. The skeletonized bridges, plates, and barrels are fully exposed, turning the face of the watch into a kinetic display of horological engineering. The 14-day power reserve is made possible by a linear arrangement of seven series-coupled mainspring barrels, a configuration that becomes a dramatic visual element running across the movement and visible through the sapphire crystal above and the case back below.

The manual-winding movement at the heart of the MP-11 is a testament to Hublot's in-house manufacture capabilities. Seven barrels working in series rather than in parallel is an engineering solution that delivers extraordinary autonomy without sacrificing the slim winding torque profile required for daily use. The result is a 14-day power reserve — a specification that separates this watch from virtually all other timepieces in its class and makes it a true conversation piece among serious collectors. The movement's architecture is deliberately theatrical, designed to be admired as much as relied upon.

On the wrist, the 45mm Magic Gold case commands immediate presence. The combination of the warm gold tone, the deep transparency of the sapphire dial revealing the mechanical complexity within, and the supple rubber strap creates a watch that reads as both sporty and grand complications-level serious. The rubber strap ensures comfort for everyday wear while nodding to the Big Bang family's sporting DNA. At 45mm this is a bold, statement-making watch that rewards close inspection.
