Seamaster Deville Authenticity Check

Hey there,

I am looking at purchasing a Seamaster Deville with gold beads of rice bracelet.

Before proceeding with anything, I want to check if everything on the watch looks authentic/original.

I received another Seamaster Deville which was missing a bezel (and actively looking for), so I don't want to have to hunt more original parts down. It has been a painful process so far.

Unfortunately, I don't have much more information than what is in the images, the person I am purchasing from is an antiques collector and can't take out the movement so don't have the case number, movement calibre etc. if anyone has information on that, it would be appreciated.

I also think this is likely an original dial but with a heavily scratched crystal it's difficult to tell (particularly regarding the minute marks)

In any case, I suspect this might be a later 14910 or, perhaps, a 166.020.

Here's an excellent discussion of the possible references to pick through:

Bracelet is junk. Very worn and stretched. No value

Watch the same in wear.
