Hublot MP-10 Tourbillon Just Got Wilder With New Sapphire & Ceramic Cases

Hublot MP-10 Tourbillon: A Daring Duo in Sapphire and Black Ceramic

Hublot, known for its bold and unconventional designs, has once again defied horological norms with two new takes on its MP-10 Tourbillon. Originally unveiled last year to both fanfare and confusion, the MP-10 broke the mold of traditional Hublot designs—eschewing the Big Bang and Classic Fusion templates in favor of pure mechanical spectacle.

Now, it returns in two equally radical forms: one in deep black ceramic, the other in transparent sapphire.

Let’s get something out of the way: this is not your everyday watch. With a 41.5mm width, 54.1mm lug-to-lug, and a towering 22.4mm thickness, the MP-10 is a wrist-dominating sculpture. The watch isn’t trying to be discreet—it’s here to show off, spark debate, and maybe even provoke a few double-takes in boardrooms and boutiques alike.

Despite sharing the same design as the original titanium release, the new models couldn’t feel more distinct

. The black ceramic variant keeps things sharp and stealthy, featuring a microblasted finish at the ends and a massive sapphire crystal window up top. The black rubber strap integrates directly into the case—a quirky inversion of traditional lug designs—and it’s held in place with visible bolts and a hybrid ceramic-titanium deployant clasp.

The sapphire version is a horological ghost—hauntingly transparent, with polished case components and an anti-reflective display crystal. Even the strap is clear rubber, maintaining the illusion of floating mechanics on the wrist. It’s less a watch and more a kinetic art piece.

What makes the MP-10 more than just a provocative design experiment is its groundbreaking mechanical innovation. Gone are the standard hands or rotor. Instead, hours and minutes rotate under a so-called “invisible magnifying glass,” with luminous numerals that lean toward subtle grey tones. Time is read vertically, not radially, and flanked by a pair of white gold sliders—the watch’s unique linear mass winding system. These slide like elevator weights along shafts to generate energy in lieu of a rotor. It’s a visual treat and a mechanical feat.

The bottom half showcases an inclined tourbillon set at 35°, partnered with a rotating barrel power reserve indicator in green, orange, and red—color-coded for urgency. The seconds are tracked around the tourbillon by an indexed ring. All of this aligns vertically, allowing the user to read time, power, and movement progress in one stacked glance—functional and dramatic.

Inside is Hublot’s in-house HUB9013 movement, built with 592 components and 66 jewels.

It runs at 21,600 vph and provides a 48-hour power reserve. The back, where one might expect traditional finishing, reveals only industrial support structures, sliders, and the push-activated setting crown. In a world obsessed with transparent casebacks, Hublot reminds us that the party’s on the front.

Yes, it’s enormous. Yes, it’s eye-wateringly expensive—the ceramic version (Ref. 910.CX.0000.RX) runs at $330,000, and the sapphire (Ref. 910.JX.0001.RT) at $440,000. Only 50 and 30 pieces of each will be made, respectively. But love it or loathe it, the MP-10 refuses to blend in. It’s Hublot’s reminder that innovation isn’t always elegant—sometimes it’s eccentric, loud, and unapologetically strange. And maybe, that’s the point.
