This is a VERY nice example of a Parnis flieger.  I purchased it new sometime in 2012-2013 and just don't wear it anymore.  It has virtually no visible scratches on the case, bezel or crystal.  I've looked it over and can't find any.  The indices and hands are lumed and the lume is still strong.  It is on a soft aftermarket leather strap; the original strap was one of those stiff plastic feeling sealed leather bands and was not comfortable.
The exhibition caseback shows off a detailed guilloche style patterned rotor with that same pattern continued onto the rest of the movement itself.  I don't find this level of detailing on most of my current microbrand or entry level Swiss watches (think Tissot, Mido, etc.).  All in all, this is a really well done watch and I honestly just don't wear it anymore.  It will come in an unmarked box as it had no original box when I bought it.
Please reach out with any questions.
