Clueless vintage owner

[Clubber]

Hey everyone,

By pure chance, I met someone whom inherited a 6265 from his father (first owner) and wanted to let it go as it wasn't his style and never used it.

I inspected the watch to the best of my very limited knowledge and checked the serial number with the papers and once they matched, I pulled the trigger.

The only information he had from his father was that the watch had a dial replacement some 30+ years ago (hence the service dial)

I also sent the certificate number to my AD and they could only confirm the case and bezel matched but nothing else.

Searching through this forum and many other vintage sources, I established the watch as 1971 but couldn't gather any other infor regarding how original it is.

The watch has screw down pushers but also riveted bracelet. I know these vintage daytonas came in various combo's but I would like to learn as much as possible from the pro's here.

Here are a few photos, I would appreciate any constructive input.

Thanks in advance,
