Casio Youth F-91WS-8 Quartz Women's Watch An absolute must for retro lovers; this used to be the happening thing of the â80s; only that it didnât have all the functional wonders like it does now. Good for daily wear, for it is built strong; enough to handle the stress of daily activities and it does from the cover of a great, old-fashioned design. A beautiful, stylish combination of yesteryearsâ fashion and technology of the new millennium, creating an everyday wear fully worry-free.
