Help with this watch info....

[Llamacide]

My father gave me this SeaSport divers watch many years ago... Recently I have tried to find information regarding its origin but I have turned up nothing. It has a clear crystal back, making the movement visible. It is a Sea Sport 21 jewel automatic using a Myota movement. I see no other markings. Any help is appreciated. Thx.

well, it appears you know as much about it as anyone else here would... that it's a SeaSport with a Miyota movement. Miyota is a japanese movement, but I would venture a guess that the rest of the watch is made in china. Looks like a mineral glass crystal, and not sapphire, based on the scratches.

Hmm, ok....
well, it keeps good time... But it is showing its wear.... But for an everyday work and wear watch its been great.

I have searched for Sea Sport watch on the web and there is not one bit of info...

It looks like it may be a Rolex Sub proportioned copy... Any thoughts?
