Need expert advice for a Red Sub

[Aston]

Hello,

Could you please tell me what you think about this one:









The ref. of the bracelet is 78360 with End Links 501 (sot nor original, I don't know the date of production of this one).

The seller told me that the serial is 2,2 millions and the dial is original.

What do you think about the value of this watch? The fact that the bracelet is not the original one is really a negative point?

Thanks a lot for your feedback
