Is this a franken watch?

[aliv023]

Hi guys,

a couple of months ago I bought my first 1675. I bought the watch because I loved the look of it is my first Rolex and since then I started learning about the 1675 story and details. I got the watch for $14.500. But the more I learn the more things are not adding up. I will list all the things I found and hopefully you guys can help me get more clear, so I learn from it. The watch is a MK1 Long E matte dial with the large arrow hand.

1. Is there any specific name for this fading of the color? It is a mix of pink / red and light purple.
2. The insert on the back is blue and not red. I am not sure if this means it is not correct / original. As far as I was reading it should have been red.
3. The date wheel has an open 9 and 6 and not a hooked 7.
4. The hands seem to be newer than the rest, because it is white and does not have the same patina as the rest.
5. The bracelet seems to definitely not to be original, it has a 78360 stamped on it. The endlinks: 501B and clasp: M12 and 78360
6. Now the serial number is the most tricky one, in the invoice from the dealer it is referred to starting with 1399... But it does not add up with the MK1 matte dial. The serial number, specially the upper part is almost invisible. I tried to see the number under the loupe and in my opinion it is not a 3, but clearly a 5, so the serial number would be 1599... So in this case it could make sense that it is a MK1 matte dial, right?
7. The date on the case back is stamped with: II 66 and the caliber is 1570. If it is really a 1599... serial number, shouldn't it say 1967?
8. The lugs seem to be polished as those nice edges which I now understand should be there are not.
9. If I put the watch under UV light, and then turn off the light, nothing glows, also not the "newer" looking hands.

I appreciate any help guys, I love the watch, but really want to understand as much as possible and learn from it for the future.
