The dial says it's a 6118 calibre...

which means it is the same basic calibre as the 21 jewel 6119 that is day/date.

Compared to other pictures I see on google; this one looks to be in very good condition.

The watch dates to the 70s and is probably not as frequently found as the 6119 models. It's a good calibre and given it's apparent condition should last you a long time.

I'm guessing a serious collector would grab this one at between $50 and $75 but it probably isn't worth much more givem what I see on ePrey and some of the sales forums.

Check out the 70s catalogue picture archives on the SCWF; you may find it there and a model number.
