The Hublot caliber HUB9011 is an in-house mechanical movement manufactured by Hublot for Hublot watches. It is a skeletonized manual-wind movement with 14 days of power reserve on a full wind.

HUB9011 VS MP-11:

Although Hublot’s official website offers a vast amount of information and 3D graphics of their timepieces and movements, the caliber labeling can be confusing. Calibre HUB9011 is apparently the caliber MP-11 made for a few newer references listed above (specifically the Magic Gold and Blue Sapphire models).

Perhaps this quote by Hublot’s CEO explains it better:

“By marrying its famous MP-11 manufacture movement, characterised by its atypical and highly visual construction, with two new materials developed by our engineers – Magic Gold and Blue Sapphire –, Hublot once again brilliantly illustrates its “Art of Fusion”. The art of being avant-garde, different and unique.” –source

So, is it the caliber MP-11 or HUB9011? If the answer is HUB9011, then what exactly makes it different from the MP-11 that warrants a separate caliber number?

Edit: All of the MP-11 watches are listed as having the HUB9011. Hublot should clarify which designation is the actual caliber number.

14 Days Power Reserve:

The caliber HUB9011 offers a whopping 14 days power reserve. Imagine not having to wind your manual wind watch for half a month. By the time you need to wind it, you may forget that it’s a mechanical watch. Hublot frames the engineering behind this in the blurb below:

“To achieve an exceptional power reserve of two weeks, the brand has developed an original movement architecture integrating seven series-coupled barrels. The power reserve appears directly on a cylinder located to the left of the seven barrels, opposite the ‘DAY POWER RESERVE’ indication in blue or gold on the anti-reflective sapphire crystal. By adopting the shape of barrels, the sapphire crystal creates a magnifying effect on this important indication.” –source
