The Hublot caliber HUB1280 is an in-house movement manufactured by Hublot for Hublot watches. It is an automatic flyback column wheel chronograph. One unique offering of this caliber is the view of the column wheel from the dial side of the movement.

Protected by four patents, this caliber was announced in 2018 as an update to the original Uniqo that first launched in 2010.

Original Unico VS This Unico 2:

The Unico 2 (HUB1280) is the second iteration of Hublot’s Unico line of movements. This version is 1.3mm flatter (6.75mm thick), allowing for slimmer case designs and fitment in the unisex 42mm cases rather than the original Unico which was made for 45mm models.

Flyback Function

Hublot chronograph watches equipped with the UNICO HUB1280 movement can switch between timing measurements with a single press, instead of three.

  1. Activate the chronograph by pressing push-piece (A).
  2. To go directly to the next sequence, press push-piece (B), which will restart your chronograph with a new time measurement.

Learn more about the flyback chronograph complication.

In Hublot’s Own Words:

“The Unico 2 caliber was designed to equip smaller chronographs and also open the world of Hublot to new enthusiasts. It retains the unique design of its former version with a double coupling system visible from the dial side as well as a 72-hour power reserve. But thanks to various technical optimizations, including the introduction of a new, flatter automatic winding system, it has been reduced by 1.3 mm in thickness.”

Dial Side:

Notice the column wheel mechanism visible from the dial side of the movement at 6:00.

Congratulations on this interesting article. But the front view shows the Unico 1 caliber (HUB1242) instead of the Unico 2 (HUB1280)

Thank you, I see you have already replaced the photo. The best way to recognize the HUB1280 caliber on dial side is to observe the seconds clutch wheel because it has 60 elastic blades instead of the classic 5-arm wheel with 60 triangular teeth of the HUB1242 caliber. Moreover, during the start-stop of the chronograph, you can observe that the clutch wheel of the HUB1280 tilts to perform its clutch function. It is this particularity, combined with the use of backlash compensation gear profiles, which eliminates the start jump that is the only weak point of classic horizontal clutches. The… Read more »

Hi, Adam, no, there are no gold components. In contrast, gold is used as a coating The oscillating weight could have been gold, but it is not.

Never could understand how people paid Hublot prices for watches with an ETA engine

I started tonight’s “journey” trying to sort out who mfg’s the movement for Cyrus Watch Group which led me to some conglomerate of fine Swiss watchmakers whose name escapes me atm- but when I clicked on their movements-I then saw the HUBXXX model number (inferring the Swiss Cyrus group movement was somehow 2-removed from this Hublot movement?) of which I’m not interested in UNTIL I read the top post from Christophe Lyner. @Paul; did you read that post from the Hublot engineer? Maybe it wasn’t here when you created your snarky post? But as I just said, am not a… Read more »

Well, that’s me told! Am so glad I admitted my ignorance and stupidity then! Though did speculate that based on the supply/demand and quantities of Hubly shipped, that they’d probably use another mfg’s modified movement. You just say ETA & Sellita’s. But never specify if they’re being modified? That’s really the crux of my challenge. For as also said, it’s one thing to drop a bog standard ETA into a “premium watch” case and slap a $85K price tag on it; it’s another if they’re fine tuning it and making custom upgrades internally that are 18k gold etc – as… Read more »

I call BS on this comment. Where do you see ETA in the movement above? It’s nothing like anything ETA ever made. Did you not bother to read the movement engineer’s post above before spreading false information?

That wasn’t obvious from your original comment. This page is obviously for discussing their in-house movement. Name calling because someone questioned your statement? Ha we’re all here for the hobby but you come in trolling. Have yourself a nice day troll!

Thank you very much for your intervention Roy. In fact, Hublot prefers to use movements designed and assembled in-house and movements from the LVMH group, of which we are a part. The movements that are not produced in our group are entirely made in Switzerland and have nothing to prove either in terms of reliability and quality. The hublot.com website presents interesting new videos of our workshops and our manufactured movements: https://www.hublot.com/en-ch/craftsmanship. Everyone will be able to form a more objective opinion about our know-how and our watches.
