The ETA caliber 7754 is an automatic chronograph watch movement. It is Swiss made with 25 jewels. This movement is based on the popular ETA caliber 7750, but with the addition of a 24 hours hand (GMT) complication for tracking a second time zone. As of 2/27/20, the official ETA website lists this caliber as unavailable.
ETA 7754 VS. 7750:
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.
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.
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.
