Because it is not that. It is an SRPD95 or such.It has a tag on it indicating it’s a SRPD27. It doesn’t look like the images of a SRPD27 when I google it.
Yes I can confirm, with the exception of the drilled lug holes (nice!) and the use of a non-screwdown crown tube, they are identical cases to the SKX007 and all its variants (SKX009, SKX011, SKX173, etc).You can pop in a 7S26 or 7S36 as well as the 4R36 it was designed for and the stem and crown is backwards compatible if you choose to use a 7SX6 movement...I do not know if they are dimensionally similar enough to use the plethora of mod parts out there..
Amen to that !..To the OP, adding a Prospex hang tag to a 5KX watch reeks of dishonesty so if not a "fake" I would call it a "fraud" at minimum.
