Hublot Big Bang MP-11 Power Reserve 14 Days

About This Watch

The Hublot Big Bang MP-11 pushes the boundaries of mechanical power reserve to an extraordinary 14 days — 336 hours of continuous running from a single winding. This feat is achieved through an unprecedented arrangement of seven mainspring barrels connected in series, visible as a dramatic linear stack running across the dial. The HUB9011 hand-wound caliber is one of the most architecturally striking movements in modern watchmaking, with the barrel train displayed horizontally like cylinders in an engine block. A power reserve indicator on the right side of the dial displays the remaining energy, and watching it slowly deplete over two full weeks is a uniquely satisfying horological experience. The 45mm titanium case with its characteristic H-shaped bezel screws houses this extraordinary mechanism with sapphire crystals on both front and back providing full visibility of the movement. The barrel arrangement required a completely unconventional dial layout, with the time display occupying the lower portion of the face while the seven barrels dominate the upper section. At 21,600 vph, the lower frequency helps conserve energy across the extended running period. The MP-11 stands in a rarified category of extreme power reserve watches, competing with far more expensive complications from traditional haute horlogerie houses. For collectors fascinated by mechanical endurance and visible engineering, it represents one of the most compelling value propositions in this niche category.
