The Hublot caliber HUB1280 is an in-house movement manufactured by Hublot for Hublot watches. It is an automatic flyback column wheel chronograph.

Unico 2

This caliber is the second iteration of Hublot’s Unico line of movements. This version is 1.3mm flatter, allowing for slimmer case designs.

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.

Notice the column wheel mechanism visible from the dial side of the movement.

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.”
