This is a fake U-Boat that caught our attention at the Basel International Watch Fair in the past. They call it Chimera 48 Carbonio GMT (reference number 7177). This is an automatic chronograph driven by an ETA 7754 movement, which is a GMT version of the 7750. The movement is equipped with a custom rotor made of 925 silver, which they rotate to give a devastating appearance.
The case is made of forged carbon, and each piece forms a unique swirl pattern. 48 mm is the diameter, but does not include the huge titanium top cover. A larger crown does not always mean deeper water resistance, because the rated water resistance of this piece is only 50m.
The dial is a stenciled sandwich style with matte black on the top and Super-LumiNova on the bottom. The Greenwich Mean Time hand adds some features through a cool orange wavy arrow pointing to your second time zone. Best replica watches websites
