The ETA caliber 7754 is an automatic chronograph watch movement. It is Swiss made with 25 jewels.

As of 2/27/20, the official ETA website lists this caliber as unavailable.

ETA 7750 VS. 7754:

The caliber 7754 is based on the ETA/Valjoux 7750. The main difference between the two movements is that the 7754 has an additional GMT hand (second time zone) complication.

Custom Rotors:

You will find that many of the brands using the ETA 7754 will customize the rotor. Some of these brands will give the caliber a different designation after the customizations are made.

Uboat Caliber 7754 325 Silver Rotor

For example, the U-Boat Chinera 48 Carbon GMT is powered by an ETA caliber 7754 movement, but modified it by flipping it around 180 degrees to create a destro watch. The custom rotor is crafted out of 925 silver.

Glycine Caliber Gl754

Another example is this Glycine watch with 7754 and a custom rotor with a propeller airplane design carved into it. They call this the caliber GL-754.
