Help verifying a deep sea

[ramilio]

Hi,

Keen to get others opinion on this deep sea that's coming up at a local auction (picture attached)

I'm a little skeptical given I haven't seen this type of box before - But hoping others might be able to give some advice on the watch? Is there anything that suggest that it's not right?

I've been told that the watch comes with paperwork, but I'm yet to see it or get a serial number.

Any advice appreciated.

Thanks
Ramilio
