Fortis Flieger real or fake?

I just picked up this Flieger from Fortis. I have seen many fakes of this specific watch, but they always look too new. This one looks to have a real tritium dial and cracking in the hands . Lemme know whatcha think. I haven’t opened the case back yet, but it is running 2-3 seconds off per day for one week of wear(more accurate than any fakes I have encountered)
