Is my Breitling 1884 Bentley 01/50 J44362 real or fake?

SOURCE: Real or Fake

check a bunch of things...even great fakes slip up on one or two details

check the luminous markers, are they painted well?
check the bezel luminous marker, does it match an authentic?
check the wing logo on the dial
look at the font for the date
look at the band pins (they should be screws-round or flat depending on model)
check the crystal, should have no reflection and a purple hue when viewed at an angle
under the lugs will be a date etched in to the case
the bezel will have a small "B" etched in between 11 and 12 on the side, not the face

Bottom line, unless you have paperwork in hand and a verification that the seller bought it from Breitling, you are probably looking at a fake
