The numerals are commissioned original typography

Apeloig's numerals were drawn for this watch and exist nowhere else. That makes them harder to copy than numerals taken from a common typeface, because a counterfeiter cannot obtain the letterforms — they have to be redrawn by eye, and redrawing type by eye produces characteristic errors in stroke weight, counter shape and spacing. Compare the numerals against a documented example at magnification; this is one of the better dial checks in the catalog.

A micro-rotor constrains the case thickness

Expect a movement whose winding weight is recessed into the plate rather than sweeping above the bridges, and a case built thin around it. A thick case, or a full overhead rotor visible through the display back, is inconsistent with the caliber the model is defined by.
