A few Super Sea Wolf questions....

[sfglenrock]

Hi guys. I just recently joined your forum and I'm amazed by all the vintage Zodiac information. I just picked up my first Zodiac, a Super Sea Wolf 75ATM. I'm really impressed by the watch but have a few questions for the experts.

I was told it is a 70's watch but is there a way to get the actual year?
Not sure of the movement but should there be a quickset date?
I've seen the same model with Date only and Day/Date. Is that correct?
What type of strap/bracelet did these originally comme with? I think I've seen both.
Were all this style Zodiac SSW cases blasted or were some polished?
Any way to tell from the pics if this is original? It looks to be.[/li][/list]

Any help would be appreciated. Thanks.

Here's a few pics...
