authentic Patek Philippe 3700/1a. Need help fast!!!

[ciceroyeah]

This is a franken Patek, and a poorly assembled one at that. The case and dial are fake, and the movement and hands are real. The movement is a vintage 28-255, and is clearly genuine. Likely it was salvaged from another less valuable watch, but it probably is in bad condition and would need expensive servicing. Which could not be done because the rest of the watch is fake.

However, no nautilus of that era ever had an open case-back, and the steel square around the date-window is all wrong. Furthermore, the dial is brighter than the nearly-black original vintage dials, and the horizontal lines are too fat (a real 3700 has 3 raised lines intersecting the sides of the date window, not 2 raised lines as in this example). Further, you can see the dial was made for a wider set of hands by noticing the gap between dial and the circumference of the hands stack, likely because it was meant for a cheap asian 21j movement or a ETA 2824.

This was assembled from parts with an aggregate value around 3 thousand USD and is worth nothing more than that.
