Hublot Big Bang MP-11 Power Reserve 14 Days Sapphire 45 mm Transparent Dial Polished Sapphire Crystal Rubber Strap 911.JX.0102.RW

To obtain a two-week power reserve, Hublot has developed an original and spectacular design movement integrating seven barrels paired in series. To enable the transmission of energy between the horizontal axis of the barrels and the vertical wheel driving the hour/minute displays, the Manufacture has used a very rare system in watchmaking: a 90-degree return by means of the helical gear wheel, of the “endless screw” type.
