    Frank: Technically "Chirality" is a term that only applies in chemistry.

    If it's backwards then it's a right-handed sextant. The normal sextant is clearly designed for a left-handed user. At some point in the 19th century, via spontaneous symmetry breaking, the standard design became frozen with the minority chirality. It's the revenge of the southpaw navigator!
