Vintage Casio's are en vogue. In fact, they even brought back a vintage product line since there was so much demand http://www.casio-intl.com/in/en/wat/vintage/

If you've ever paid attention to the wrists of the SF hipster crowd vintage digital/calculator watches are common. American Apparel even sells them in store: http://store.americanapparel.net/category/index.jsp?catId=ca...

Intentional or not, the silver watch is a nice throwback while the matte black is distinctly modern IMHO.
