Help with Tudor 94010

[franzumb]

Hi, Im looking for your help on this tudor being offered to me at 8000 USD.

I am hoping to see your opinion on the movement. Specifically on the engravings in the rotor. The movement should be an ETA 2776 from what i've found. I examined the dial through UV, the seconds hand appears to be earlier since it shines in only slight darkness and does not have the same color as the others. The lume seems substantial on the lume plots and hands but has sort of bubble. Im wondering if the watch had water damage of some sort. The bracelet was bought separately to complement the watch. Another note is the crown that reads "Brevet" which I think corresponds to a much earlier watch but I am not sure as these are very rare. Hope you find this watch interesting.

I uploaded the images through Imgur to preserve the quality.

Thanks for any help and good luck to everyone.
