I'm with Rene on this one, I don't see sufficient evidence to jump to the conclusion of it being a fake. Some say indeed that all these Breitling twin planes buckles are fakes anyway because Breitling never made them.

In cases such as these I'm afraid that the "it looks different so therefore it's fake" conclusion lacks evidence, unless you have something more to go on I'd say maybe they're both fakes, maybe neither are, further detailed research is called for rather than a quick knee-jerk reaction.

: Hallo Rene!

: let'check the backside from the buckle

:

: left one - engraving very accurate on this original buckle

: left one - bad engraving and faked in the same way, as we
: find the Heuer buckles

: the material from fake ones also have a different optical
: and haptic impression (and the fake is a oversoft material)

: original = frosted fake = glossy

: at least: take the fake one between 2 fingers from both hands
: and you can easily bend the buckle - no tool needed to change
: a bracelet 😁😂
