Curvex model .
Quartz .
Perfect accuracy.
New leather band . Original black band included .
This Gruen was made by the Gruen new parent and is a relatively new watch . Although does not have the historical heft of the watches that bore the Curvex storied name 60 plus years ago .
Still this is a handsome and reliable modern Curvex that looks good and wears great .
I put a matching strap and polished it lightly and now you have fun and wear it like you stole it .
