·Cheers, thanks both. Going to try to make some time to go see the watch in person again this weekend or next.
The dealer has confirmed that the bracelet is dated 1967 and the endlinks are HELs. Strangely, they've said there's no serial number. My guess here is that they didn't realize the serial might be covered up by the bracelet - I'd be a bit surprised if the number was polished off given the condition of the rest of the case.
One more photo of the watch - perhaps a better angle of the endlinks:
Usually a very important point concerning the originality of end links is the engraving but this isn't shown in the second pic...
Should look like that:
As they could have been bent or damaged in a way I think it is very hard to tell from your picture if they are original or not 🙁
